Hidden Costs of Buying a Home in Michigan 2026: The Property Tax Pop-Up & 9 More Surprises That Blindside Buyers

The hidden costs of buying a home in Michigan typically add 3% to 6% of the purchase price to your first 12 months of ownership — roughly $12,000 to $24,000 on a $400,000 home, on top of down payment and standard closing costs. The single biggest is the Michigan property tax pop-up under Proposal A, which can raise year-two taxes by $1,500 to $10,000+ depending on how long the seller owned the home. Other major hidden costs include prorated taxes at closing, first-year escrow shortage letters, water and sewer liens in Detroit, Oakland County drain assessments, HOA capital contributions and special assessments, clay sewer line failures in pre-1970 Metro Detroit homes, and the statistically likely first major repair within six months of closing.

The Pizza-on-the-Floor Moment

The pizza is on the floor.

It's the first night in your new house. The living room is full of taped boxes. The Wi-Fi isn't set up yet. Your phone has 12% battery. You and your spouse (or your roommate, or your dog, depending) are eating cold pepperoni out of the box because the kitchen is somewhere under a cardboard mountain and you don't even know which box has plates.

It's the best night of your life.

Eight months later, in February, an envelope arrives from the city. You open it standing at the kitchen island. Your property tax bill is $2,800 higher than the number your lender used to set up your escrow.

Welcome to homeownership in Michigan.

I've been a licensed real estate agent in Michigan for 24 years (License #309650). My team has closed over 8,000 transactions across Metro Detroit with a 99.1% list-to-sale ratio and 3,000+ verified five-star reviews. I've personally watched, in real time, more buyers get blindsided by post-closing costs than I can count, and almost every single one of them was preventable.

This is the post I wish every buyer in Oakland, Macomb, Wayne, Washtenaw, and Livingston County would read before they wrote their first offer. It's long. It's specific. It's built on data from thousands of closed transactions, not speculation.

If you actually use it, it will save you somewhere between $5,000 and $50,000 over the next decade.

Let's go.

The Headliner: Michigan's Property Tax Pop-Up

Michigan's property tax pop-up is the dramatic property tax increase that happens the year after you buy a home. Under Proposal A (1994), annual tax increases are capped at 5% or inflation while the same owner holds the property. When the home transfers, that cap is removed and the taxable value resets to the State Equalized Value (roughly half of market value). For Metro Detroit buyers, this typically means a $1,500 to $10,000+ year-two property tax increase.

If you read nothing else in this post, read this section.

In Michigan, when a home changes hands, the property tax can jump dramatically the year after closing. It's called the pop-up tax, and it's the single biggest hidden cost I see crush new buyers in this market.

Key Terms Defined

• Proposal A: Michigan constitutional amendment passed in 1994 that caps annual increases on a property's taxable value at 5% or the rate of inflation, whichever is less, while the same owner holds the property.
  
  
• Taxable Value (TV): The dollar value the property is actually taxed on. Capped under Proposal A while a single owner holds the property.
  
  
• State Equalized Value (SEV): Set by the local assessor at approximately 50% of the property's true cash (market) value. Uncapped.
  
  
• Uncapping: What happens to taxable value the year following a transfer of ownership. The cap lifts and taxable value resets to the SEV.
  
  
• Principal Residence Exemption (PRE): Exempts a homeowner's primary residence from approximately 18 mills of local school operating tax. Must be filed with the local assessor by June 1 (for summer taxes) or November 1 (for winter taxes). Form 2368.
  
  
• Property Transfer Affidavit: Michigan Department of Treasury Form 2766/L-4260. The buyer must file with the local assessor within 45 days of closing. Penalty for late filing: $5/day up to $200.

How Michigan's Pop-Up Tax Works (Proposal A Explained)

In 1994, Michigan voters passed Proposal A, which capped annual increases on a home's taxable value at 5% or the rate of inflation, whichever is less, as long as the same owner held the property. Great policy for longtime homeowners. It protected grandmas from being taxed out of the neighborhoods they built.

But the second the property transfers, that cap blows off. The taxable value resets to roughly the State Equalized Value (SEV), which is approximately half of the home's market value. The longer the seller owned the home, the bigger the gap between what they were paying and what you're about to pay.

For the official statutory framework, the Michigan Department of Treasury's Change in Ownership and Uncapping of Property page lays out the cap mechanics in detail, and the underlying statute (MCL 211.27a) is the legal source.

How Much Will My Property Taxes Go Up After I Buy a Home in Michigan?

Here are the ranges I see all the time across Metro Detroit:

That's anywhere from $125 to $800+ extra per month in escrow the year after you close. On a house you already signed for.

"On a $625,000 home in Birmingham where the seller has owned for 25 years, I routinely see year-two property taxes jump from $7,200 to $14,000+. That is a $565/month escrow swing the buyer's lender did not include in their pre-approval math." — Michael Perna, The Perna Team

Why Even Smart Buyers Never See It Coming

A few reasons, all of them maddening:

Out-of-state lenders are clueless about Proposal A. They plug in the seller's current tax number and move on. The MLS shows today's taxes, not the reassessed taxes. Nobody in the middle of a live transaction is incentivized to slow the train down and scare you.

The killer detail: the assessor doesn't send the adjusted tax notice until February of the year after you close. So you don't even find out the real damage for 6 to 14 months.

There's a second, related trap most buyers also miss. If you don't file your Principal Residence Exemption (PRE) by June 1 of the year you close, you eat roughly 18 extra mills of non-homestead school tax for that whole tax year. That's another $1,500 to $4,000 straight to the wall, on top of everything else.

What We Do on Every Buyer Transaction

Before we write an offer on any property, my team pulls the SEV, applies current millage, and runs the actual post-closing tax number. Then we hand that projection to the lender so the buyer's real DTI and real monthly payment are baked in from day one. This is the same protection logic we apply on our Metro Detroit first-time buyer guide, and it's the difference between a buyer who sails through year two and a buyer who is shopping for a HELOC in February.

No pop-ups. No panic email in July.

Proposal A was designed to protect longtime homeowners from being taxed out of the neighborhoods they built. Good policy. Absolutely brutal on the buyer who doesn't know it exists.

The Full Hidden Cost Inventory: 10 Costs That Blindside Metro Detroit Buyers

Beyond the property tax pop-up, the most common hidden costs of buying a home in Michigan include prorated property tax credits at closing, first-year escrow shortage letters, owner's title insurance (when buyer pays), water and sewer liens (especially in Detroit), Oakland County drain assessments, HOA capital contributions and special assessments, septic and well costs, utility shock for first-time homeowners, immediate move-in costs of $3,000 to $8,000, PMI, and the statistically likely first major repair within six months.

The pop-up tax is the headliner. It's not the only act. Here's the rest of what consistently blindsides Metro Detroit buyers, in roughly the order they tend to hit you.

1. Prorated Property Taxes at Closing

Prorated property taxes at closing in Michigan can cost a buyer $2,000 to $5,000 unexpectedly, especially when closing in June before the summer tax bill drops and the seller has prepaid the previous July's installment.

Michigan collects taxes both in arrears and in advance, depending on which bill we're talking about. Summer taxes (typically the larger of the two bills in most Metro Detroit communities, since many school districts bill 100% of school operating tax on the summer cycle) bill July 1 and technically cover July through June. Winter taxes bill December 1.

Depending on when you close, you're either crediting the seller for taxes they've prepaid or getting credited for taxes they owe. The math is rarely what buyers expect.

Close in June, before the summer bill drops? You might owe the seller $2,000 to $5,000 at closing for taxes they paid in advance the previous July. Nobody warned you because the lender's Loan Estimate buried it in prepaids.

Especially sneaky in Bloomfield Township, Birmingham, Northville, Novi, and Troy, anywhere taxes run $8,000+/year.

2. The First-Year Escrow Shortage Letter

The first-year escrow shortage letter is the lender's lump-sum bill demanding $1,500 to $4,500 in catch-up funds plus a $200 to $500 monthly payment increase, typically delivered 12 to 14 months after closing when Michigan's property tax pop-up makes the original escrow account insufficient.

This one shows up 12 to 14 months after closing, and it's the chef's kiss of pain.

Your lender set up your escrow using the seller's tax number (low). Then Michigan uncapped your taxes (high). Then your insurance premium went up. Your escrow account now has a deficit AND needs a bigger monthly cushion going forward.

The letter gives you two options: pay the shortage in a lump sum, or spread it over 12 months. Either way, your monthly payment is going up.

Typical hit: $1,500 to $4,500 shortage plus $200 to $500/month higher payment going forward.

Most buyers genuinely think their mortgage payment is fixed forever. The principal and interest are. Everything else isn't.

3. Title Insurance (the Owner's Policy Nobody Explains)

In Michigan, owner's title insurance is customarily paid by the seller per the Michigan Land Title Association's published guidance. But in competitive Metro Detroit markets, buyers often agree to pay it (typically $1,200 to $3,500) to strengthen their offer. The lender's policy, around $500 to $1,500, is paid by the buyer.

Lender's title insurance is mandatory and buyers accept it without question. Owner's title insurance is "optional," and in Michigan it is customarily paid by the seller per the Michigan Land Title Association's published consumer guide. But in a hot market, that customary practice negotiates away fast.

When buyers agree to pay the owner's policy themselves to sweeten an offer, they rarely realize they just added $1,200 to $3,500 to their closing costs.

Skip it and you're uninsured against title defects forever, on the biggest purchase of your life. Don't skip it. The cost depends on who's writing the check, but somebody is buying that policy.

4. Water and Sewer: The Metro Detroit Specialty

Unpaid water and sewer bills transfer with the property under Michigan's Municipal Water Lien Act (PA 178 of 1939, MCL 123.161 et seq.), meaning Detroit, Highland Park, and Hamtramck buyers can inherit $800 to $6,000 in prior-owner debt at closing. Oakland County drain assessments (Red Run, Evergreen-Farmington, Clinton River districts) can also appear on the winter tax bill, ranging from a few hundred dollars to over $1,500 per year depending on the district and maintenance cycle.

This is where Detroit-area buyers especially get torched. A few flavors:

Unpaid water bills transfer with the property. Detroit, Highland Park, Hamtramck, and a few others will lien the house for the prior owner's unpaid water under Michigan's Municipal Water Lien Act of 1939 (MCL 123.161 et seq.). Per DWSD's own published buyer guidance, the department transfers delinquent balances to the new property owner if the lien isn't paid at the closing table. Your title company should catch this, but I've seen $800 to $6,000 bills surface at the eleventh hour.

Water turn-on or account transfer fees in Detroit and Wayne County municipalities run $75 to $300.

Quarterly water/sewer billing in places like Royal Oak, Ferndale, Hazel Park, and Oak Park. Buyers coming from cities that bill monthly see a $600 bill land in month three and panic.

Drain assessments. This is the sneaky one. Oakland County in particular passes special assessments for drain projects through the Water Resources Commissioner's office. The Red Run, Evergreen-Farmington Sanitary, and Clinton-Oakland districts each run their own assessment rolls. These show up on your winter tax bill as a separate line item (or in some communities, as a storm water utility charge on your quarterly bill). Ranges vary widely by district and maintenance cycle, typically a few hundred dollars per year on the low end to over $1,500 per year on capital-project years.

5. Septic, Well, and "You Live in the Country Now" Costs

Septic and well systems on Metro Detroit rural properties carry hidden costs of $300 to $600 for pre-purchase inspections plus $350 to $700 every 3 to 5 years for septic pumping, with worst-case drain field replacement running $8,000 to $25,000+.

Anywhere outside the sewer district (parts of Oakland Township, Rochester Hills, most of Washington Township, Holly, Lyon Township, White Lake, Highland, Addison, Independence) you're inheriting a septic and/or a well.

Pre-closing inspections (which most buyers skip because "the home inspector looked at the house"):

Ongoing costs that shock people:

Some Oakland County municipalities also require a Time-of-Sale septic inspection. Buyers assume the seller handled it. Sometimes they didn't.

6. HOA Capital Contributions and Special Assessments

Metro Detroit HOA and condo communities charge one-time capital contribution fees of $500 to $3,500 (and $5,000 to $15,000+ at luxury golf communities like Oakland Hills and Forest Lake), plus special assessments that can hit $500 to $18,000 in the first year of ownership for roof, siding, or private road repaving projects.

Condos and some newer subdivisions (The Ridges in Novi, parts of Northville Hills, several of the newer Lombardo and Toll Brothers developments) charge a one-time "capital contribution" or "initiation fee" to new owners that the monthly dues line item does NOT cover.

Typical range: $500 to $3,500 depending on the association. High-end golf communities (Oakland Hills, Forest Lake) can hit $5,000 to $15,000+.

Add a transfer fee, document fee, or estoppel fee of $200 to $600. None of this surfaces until the title company orders the resale certificate a week before closing.

And then the assessment you didn't know about. Condo associations can pass special assessments for roofs, siding, or private road repaving. I've seen brand-new owners get a $4,000 to $18,000 assessment letter three months after closing.

Always pull two years of HOA minutes before you close. Always.

7. The "I Just Left an Apartment" Utility Reality Check

Utility costs on a typical 2,400-square-foot Metro Detroit single-family home run $350 to $600 per month blended across gas, electric, and water/sewer, with February gas bills hitting $200 to $450 alone (add 30% for older Ferndale, Royal Oak, and Huntington Woods homes with less efficient heating).

Buyers tour in May, close in July, and assume utilities will cost "a little more than my apartment." Then February hits.

On a 2,400-square-foot home in Metro Detroit with a forced-air furnace:

Buyers who just left a $140/month all-in apartment utility bill are genuinely shocked. Budget $350 to $600/month blended for a typical Metro Detroit single-family.

8. Immediate Move-In Costs Nobody Plans For

Immediate move-in costs in the first 90 days after closing typically total $3,000 to $8,000 across re-keying locks, dryer vent cleaning, HVAC service, garage door reprogramming, basic tools, window treatments, replacement appliances, and first-round landscaping.

The "I just bought a house and now I need everything" tax:

Realistic first-90-days "stuff I didn't know I needed to buy" budget: $3,000 to $8,000.

9. PMI You Thought Was Going Away

Private mortgage insurance (PMI) on a $350,000 Metro Detroit home with 5% down typically costs $150 to $250 per month, and removing it early requires a $500 to $700 appraisal at the borrower's expense plus a minimum two-year wait under standard Fannie Mae and Freddie Mac seasoning rules.

If you put less than 20% down on a conventional loan, you're paying private mortgage insurance. Buyers think, "I'll just have it removed when I hit 20% equity."

True, but the path matters. If you want to use a new appraisal showing market appreciation to hit 80% LTV early, the bank requires a formal appraisal at YOUR cost ($500 to $700), and they typically won't entertain the request until you've been in the home a minimum of two years. (You can request cancellation earlier if you've paid down principal to 80% of the ORIGINAL purchase price through scheduled amortization or extra payments.) FHA is worse. On most FHA loans written today (specifically, those with less than 10% down), MIP stays for the life of the loan unless you refinance. With 10% or more down on an FHA loan, MIP cancels automatically after 11 years.

On a $350,000 home with 5% down, you're paying roughly $150 to $250/month in PMI. That's real money bleeding out every month buyers budgeted as "toward principal."

10. The First Major Repair (the Three-to-Six Month Rule)

Roughly one in three homes will need a major repair within six months of closing, with median cost between $800 and $3,500 for items like water heaters, furnace ignitors, and sump pumps. Pre-1970 Metro Detroit homes also face clay sewer line failures running $4,000 to $15,000 that a $250 to $500 camera scope inspection catches before closing.

This isn't a cost I can price exactly, but I can price it statistically. Across thousands of closed transactions, something meaningful breaks within six months on roughly 1 in 3 homes. Water heater. Furnace ignitor. Sump pump. Garbage disposal. A tree limb. A roof leak from that one storm.

Median hit: $800 to $3,500. Occasional: $8,000 to $25,000 (roof, furnace, sewer line).

Metro Detroit special: clay sewer lines. Clay tile pipe was the standard for residential sewer lines in the Detroit area from the early 1900s through the 1960s. That means basically all of Royal Oak, Ferndale, Huntington Woods, Pleasant Ridge, most of Grosse Pointe, older Birmingham. The clay sections crack at the joints. Tree roots invade them. A camera scope before closing is $250 to $500. Full line replacement is $4,000 to $15,000. Buyers who skip the scope inspection are gambling, and the house doesn't lose often.

The Number You Actually Need

On top of down payment plus standard closing costs, plan for another 3% to 6% of the purchase price hitting you in the first 12 months, between escrow adjustments, move-in costs, utilities you underestimated, and the first repair.

On a $400,000 home, that's $12,000 to $24,000 you should have sitting in reserve.

The buyers who get crushed are the ones who drained every dollar to hit the down payment. The buyers who sail through bought at a price point that left 5%+ in the tank after closing.

That's the whole game. The house price isn't the cost of the house.

Three Real Case Studies From My Files

Names changed. Details intact. These are real deals from my 8,000+ closed transactions.

Case Study 1: The Royal Oak Couple Who Almost Ate a $7,400 Surprise

The buyers: Mike and Jenna. Mid-thirties. First-time buyers. Both teachers in the Royal Oak school district.

The home: 1,650 sqft bungalow off Main Street near 13 Mile, listed at $389,000.

The seller: A widow who'd lived there since 1987.

Read that last sentence again. 1987.

They came to me after writing their first offer with a different agent who'd ghosted them through inspection. Nice couple. Pre-approved at $415K max. Stretched to the absolute edge of what they could carry.

I pulled the property record before we even talked strategy.

Seller's current tax bill: $3,180/year. Beautiful number. Affordable number.

My uncapped projection: SEV was $182,500. Apply Royal Oak's millage with non-homestead at first (because the PRE wouldn't transfer until the following year), and we were looking at a first-year tax bill of roughly $10,600.

That's a $619/month escrow swing. On a couple whose pre-approval had $180/month of breathing room.

I called Jenna and walked her through it on speakerphone with Mike on the other line. There was a long silence. Then Jenna said, very quietly, "We can't afford this house."

Here's where it got interesting. We didn't walk. We renegotiated.

I went back to the listing agent with the actual numbers, not as a threat, as math. I asked for a $12,000 seller concession at closing, structured as a permanent 2-1 buydown on the rate. That bought their effective payment down enough in years one and two to absorb the tax hit while their teaching salaries grew into it.

Sellers said yes. Closed at $384,000 with the buydown.

Mike texted me 14 months later when the uncapped tax bill arrived. Said his hands were literally shaking when he opened it, and then he laughed, because he already knew what was inside.

The couple they were bidding against on that house? Different agent. No buydown. No tax projection. I don't know what happened to them, but I know what their February escrow letter looked like.

Case Study 2: The Bloomfield Hills Sewer Line That Ate the Honeymoon

The buyers: David and Priya. Tech executive and a pediatrician.

The home: $1.4M mid-century modern off Lone Pine Road, built 1962.

The cost they didn't see: $19,600 in post-close repairs.

This deal closed before they hired me. I came in afterward to help them sell their old house in Birmingham.

First conversation we had, Priya mentioned (kind of laughing, kind of not) that they'd had "a little plumbing issue" three months in. I asked what kind.

The kind where you flush an upstairs toilet and watch sewage come up through the basement floor drain.

Original clay sewer line. Sixty-plus years old. Tree roots had been working on it for decades. The previous owner was elderly, used the house lightly the last few years, and the line just barely held. New family of four moves in (four showers a day, dishwasher, laundry, full occupancy), system collapsed.

Total damage:

• Sewer line replacement (full excavation, permits, lawn restoration): $11,200
  
  
• Water mitigation and drywall repair in finished basement: $8,400
  
  
• Total: $19,600

Three months after they'd already drained their savings on a 20% down payment.

The killer detail: they did not get a sewer scope inspection. Their inspector mentioned it as a recommendation in the report. They were tight on contingency timeline because of competing offers, and they waived it.

A $300 inspection would have caught it. They could have negotiated a $15,000 credit at closing. Instead they paid full freight, post-close, with no recourse.

When I list pre-1970 homes now (anywhere in Royal Oak, Ferndale, Huntington Woods, Pleasant Ridge, Grosse Pointe, older Birmingham, older Bloomfield), I personally bring up the sewer scope conversation with the buyer's agent before we even get to inspection. Some agents thank me. Some get defensive. I do it anyway because of David and Priya.

They're fine now. They laugh about it at dinner parties. But Priya told me later she cried in the basement that first night, sewage on the floor of the house they'd dreamed about for two years, googling "how to sell a house you just bought."

Case Study 3: The 11pm Phone Call That Saved a Novi Closing

The buyers: Tom and Rachel. Relocating from Charlotte.

The home: $625,000 home in a 2018-built Novi development. HOA community.

The hidden cost we caught: $8,750, at 4pm the day before closing.

Closing was scheduled for a Friday morning. Movers booked. Charlotte house already sold. They were sleeping in a hotel.

Thursday at about 4pm, my closing coordinator Sarah flagged something in the resale certificate that had finally come back from the HOA management company that afternoon. (They'd been dragging their feet for ten days, itself a red flag.)

Buried on page six: a special assessment had been approved by the HOA board eleven days earlier for private road repaving across the entire subdivision. $8,750 per home, due in 90 days.

Eleven days earlier means it was approved AFTER our purchase agreement was signed but BEFORE closing. Which under Michigan law and the standard purchase agreement language means it's the seller's obligation to disclose and pay, not the buyer's.

The seller's agent had not disclosed it. I'm choosing to believe she didn't know yet. The HOA management company hadn't sent the formal letter to homeowners until the day Sarah got the resale cert.

I called Tom at 10:47pm Thursday night. He answered on the first ring because he wasn't sleeping anyway, closing nerves. I walked him through it. Told him we had three options: delay closing, close on time and eat it (no), or get the seller to credit it at the closing table.

I called the listing agent at 11:15pm. She didn't answer. Texted her. She called back at 11:40. We talked for thirty minutes. She said her seller would "never" agree to credit $8,750 the morning of closing. I told her my buyer would happily walk and re-list his hotel reservation as a permanent address until we found another house, and that I had the HOA documentation timestamp-stamped to prove the assessment predated closing.

Friday morning, 9am, at the title company: $8,750 seller credit on the closing disclosure. Tom and Rachel got their keys at 10:30. The seller was visibly furious. The listing agent wouldn't make eye contact with me.

Tom's text that afternoon, verbatim: "I owe you a steak dinner and possibly a kidney."

He bought me the steak. I declined the kidney.

The Pattern Across All Three Cases

The cost was knowable before closing in every single case. Tax projection. Sewer scope. HOA minutes review. None of it requires a magic wand. The hidden costs of buying a house in Metro Detroit follow a pattern: every one of them lives in a document somebody could have opened.

It requires an agent who treats the days before closing like the days that decide the next ten years of your finances, because they are.

The takeaway: the buyers who get destroyed by hidden costs almost never get destroyed by truly hidden costs. They get destroyed by costs that were sitting in plain sight in a document nobody read carefully enough.

The Contrarian Take: The Cost of Waiting

I'm going to push back on two pieces of conventional homebuying wisdom that are wrong, oversold, and quietly costing first-time buyers a fortune.

Wrong Advice #1: "Have 3 to 6 Months of Mortgage Payments in Reserve Before You Buy"

This advice was originally for renters needing emergency funds. Then it got dragged into homebuying advice and mutated into "have 3 to 6 months of your future mortgage payment saved on top of your down payment."

On a $400,000 home in Metro Detroit with 10% down, that's saying you need your $40,000 down payment, plus $5,000 in closing costs, plus another $15,000 to $25,000 sitting untouched in a savings account before you're "allowed" to buy.

That advice has cost more first-time buyers more wealth than almost any other piece of conventional wisdom I can think of.

Because here's what actually happens when you tell a 28-year-old couple making $140,000 combined that they need to save another $20,000 before they can buy: they don't save it. They keep renting for two more years. Rent goes up 8% each of those years. Home prices in Royal Oak go up 6% and 4%. The interest rate environment shifts twice. The $389,000 house they could have bought is now $431,000, and the payment is worse even though they "did the responsible thing."

I have watched this play out, in this market, hundreds of times. I am not theorizing.

Here's what your reserve number should actually be:

What's NOT in that number: six months of P&I sitting idle. Because if your job disappears, the answer isn't "I have six months of mortgage payments saved." The answer is unemployment insurance, severance, a forbearance request to your servicer (which they grant routinely), selling the house if it comes to it, or in the worst case a short sale. Those are the actual tools. Not a savings account doing nothing while inflation eats it.

Wrong Advice #2: "Don't Buy Until You Can Afford 20% Down to Avoid PMI"

This one makes me genuinely angry because it's mathematically illiterate advice dressed up as discipline.

Let's run it. $400,000 house, Metro Detroit, today's rates.

Path A "saved" $2,160/year in PMI and missed $16,000/year in appreciation. Net cost of waiting: roughly $14,000/year, every year you waited.

The 20% down rule is a relic from an era when home prices were flat, rates were stable, and PMI was structured punitively. None of those things are true right now. PMI in 2026 is a cost of admission, not a punishment. Pay it, get in the building, and let the building do its job.

Why Other Agents Won't Say This Out Loud

Because it sounds reckless. The safe-sounding advice ("save more, wait longer, be careful") is the advice that doesn't get an agent in trouble if the market dips six months after you close.

Telling someone to wait is professionally bulletproof. Telling someone to go requires you to have actually done the math and be willing to defend it.

I'll defend it.

The buyers I've watched build the most wealth in this market over 24 years are not the ones who waited until they had 20% down and 6 months of reserves. They're the ones who bought a house they could realistically afford with a real reserve number ($10,000-ish, liquid) and let time and amortization do what time and amortization do.

The buyers I've watched fall furthest behind are the ones who took conservative financial advice literally and are still renting in their late thirties, watching every house they could have bought five years ago sell for double.

The Caveat (Because I'm Not Insane)

This applies to buyers with stable income, manageable debt, and a house they actually plan to live in for 5+ years. If you're buying speculatively, flipping, or stretching to a payment that's 45% of your gross income, none of the above applies.

But if you're a normal household, with a normal job, looking at a normal house, in a metro area that has appreciated reliably for fifty years? Stop saving for a goal that's running away from you. Start owning.

The hidden cost nobody talks about isn't pop-up taxes or sewer lines or HOA assessments.

It's the cost of waiting.

Which Buyer Are You? Four Metro Detroit Archetypes

Different buyers get blindsided by different hidden costs. Here are the four archetypes I see most often. If you recognize yourself, that's the point.

Archetype 1: The Out-of-State Relocator

Coming from: Texas, Florida, Tennessee, or Nevada.

Profile: Tech, automotive engineering, or healthcare executive role. Household income $180K to $400K. Owned multiple homes before, considers themselves experienced.

The trap: Their confidence.

In Texas, they had no state income tax. Property taxes were higher (around 2.2%) but predictable, capped at 10%/year. In Florida, Save Our Homes capped their assessed value at 3%/year. They land in Michigan, see a $650K house in Northville Hills off Six Mile Road feeding into Northville Public Schools with current taxes of $7,200, and think "wow, that's reasonable compared to Austin."

They're not wrong about the surface number. They're catastrophically wrong about what happens after they close.

What blindsides them:

• Pop-up tax that doubles their bill year two
  
  
• Michigan state income tax (4.25%) they didn't budget for
  
  
• Snow removal, ice dam prevention, basement waterproofing, none of which existed in their last three houses
  
  
• Heating bills ($300+/month gas in February vs. $40 winter electric in Phoenix)

The mistake: they use their out-of-state mortgage broker. Who plugs the seller's current Michigan tax bill into the qualification math. Who has no idea what Proposal A is. Who delivers a Loan Estimate that's off by $700/month when reality lands.

I've literally had relocators show up to closing and learn for the first time, sitting at the title company table, that their monthly payment is going to be $800/month higher than the number their lender quoted them. By then, they've already accepted the job, sold the Texas house, and moved their kids into Michigan schools. There's no off-ramp.

What I tell them in our first meeting: "Forget every number your relocation lender gave you. We're going to run the actual post-close tax bill on every house you tour, before you write an offer, and you're going to budget against THAT number. Your income tax situation in Michigan is also worse than you think, talk to a CPA before you finalize your salary acceptance. Take 15% of your gross income off the top before we even start house shopping, because Michigan is going to take it whether you planned for it or not." Our Metro Detroit relocation guide walks through the full out-of-state checklist for buyers in this situation.

Archetype 2: The First-Time Buyer Who Drained Everything for the Down Payment

Profile: Late 20s/early 30s. Combined income $110K to $160K. Saved aggressively for three years. Has exactly $42,000 in savings, 10% down on $400K plus closing costs plus moving truck.

They're disciplined. They're responsible. They did everything the personal finance internet told them to do.

They are also one bad month away from a financial spiral that takes a decade to recover from.

What blindsides them:

• The first-year escrow shortage letter for $3,200 lands when they have $1,400 in checking
  
  
• Water heater goes ($1,800) the same month the car needs brakes ($600). They put it on a credit card at 24% APR.
  
  
• They didn't budget window treatments, bedsheets in the windows for eight months
  
  
• The fridge dies in month four. New one is $1,400 they don't have.
  
  
• Underestimated utilities by $200/month, slow bleed they don't notice until tax season

The mistake: they optimize for the down payment number and treat closing day as the finish line. It's not. It's the starting line.

They also chronically over-buy on price. They qualify for $410K and buy at $409K. They should have bought at $360K and kept $50K liquid. The house at $360K doesn't have the second bathroom they wanted. The house at $360K is fine. The house at $360K is the one that doesn't ruin them.

What I tell them in our first meeting: "I am about to give you advice the entire industry is incentivized to NOT give you. We are going to look at houses at 80% of your maximum pre-approval, not 100%. The difference (about $50K of purchase price, about $300/month) is going to stay in your savings account as your operating reserve for year one. You will thank me in fourteen months when the tax bill uncaps and the water heater dies in the same week and you don't panic."

Archetype 3: The Move-Up Buyer Who Assumes Round Two Works Like Round One

Profile: Bought their first house in 2017 in Ferndale near Woodward and 9 Mile for $215K. Now selling for $385K and moving up to a $625K house in Birmingham (Quarton Lake area, Birmingham Public Schools) or Beverly Hills (near Beverly Park, Birmingham school district) with their growing family.

This is the sneakiest archetype because they think they're experienced. They closed once. It went fine. They believe they understand homebuying.

What they actually understand is "homebuying in 2017 with a 4.1% rate on a starter house with low taxes and a thin layer of expectations." None of those conditions apply to what they're about to do.

What blindsides them:

The mistake: they anchor to "we did this before." The first transaction is not a template. Buying up is geometrically more expensive than buying in.

They also dramatically underestimate furniture. I've walked into move-up buyers' homes a year after closing and seen formal living rooms with one chair and a lamp in them. That's a $25,000 problem disguised as a decorating problem. Plan for it.

Archetype 4: The All-Cash Investor Who Thinks Cash Eliminates Risk

Profile: Small-portfolio landlord (2 to 6 doors). Or out-of-state investor from California or New York chasing Detroit cap rates. Pays cash, waives inspections to win the bid, closes in 14 days.

Then the bills start.

What blindsides them:

• Detroit water lien for $4,800 from the prior owner that the rushed title work missed
  
  
• $7,200 in back property taxes the seller "forgot" to mention
  
  
• $14,000 sewer line they would have caught with a $300 scope inspection, but they waived inspections to win
  
  
• Non-homestead tax rate (no PRE because it's a rental) adds 18 mills, $2,000 to $5,000/year more than they modeled
  
  
• Detroit rental registration, lead inspection, certificate of compliance: $400 to $1,200 plus required repairs running $3,000 to $15,000

The mistake: they confuse cash with due diligence. Cash means you don't need a lender's approval. It does not mean you don't need a title commitment review, a sewer scope, a lead inspection, a tax history pull, a code compliance check, or a tenant history.

Suburban math doesn't apply to urban properties. A house in Detroit at $85K with $1,200/month rent looks like an unbeatable cap rate on paper. The paper doesn't include the water lien, the back taxes, the compliance costs, the eviction process timeline, the property management fee, the 6-week vacancy, or the fact that the roof has 18 months of life left. Real cap rate after year one is often 60% of what the spreadsheet promised.

The Thread Connecting All Four

Every archetype gets hit because they substitute confidence for process.

The relocator's confidence is their experience in another state. The first-time buyer's confidence is their disciplined saving. The move-up buyer's confidence is their first transaction. The cash investor's confidence is their cash.

In every case, the confidence is the trap. The buyers who sail through aren't the most experienced or the wealthiest or the most disciplined. They're the ones who, regardless of their archetype, are willing to assume they don't know what they don't know, and let someone whose only job is knowing this stuff drive the bus through the unknowns.

"Confidence calibrated to actual knowledge. Everything else is hope dressed up as strategy." — Michael Perna, The Perna Team

Recognize yourself in one of those four?

A 30-minute calibration call with my team will tell you exactly which hidden costs apply to your specific situation, what your real reserve number should be, and whether you're ready to write an offer or should hold off. Call (248) 494-4698 or book a time at thepernateam.com. If we think you should wait, we'll tell you. If we think you should go, we'll tell you that too.

The 21-Step Buyer Protection Checklist

Run this in order on every purchase. We use a version of this on every transaction my team handles. This is the homeowner-facing version.

Phase 1: Before You Write the Offer

The 90-minute due diligence window. Do this between "we love this house" and "let's submit an offer." Yes, even in a competitive market. Especially in a competitive market.

Step 1. Pull the Property Tax Record (15 minutes). Go to the county treasurer or assessor website:

• Oakland County: oakgov.com
  
  
• Macomb County: macombgov.org
  
  
• Wayne County: waynecountymi.gov
  
  
• Washtenaw County: washtenaw.org
  
  
• Livingston County: livgov.com

Capture: current Taxable Value, current SEV, current millage rate (homestead AND non-homestead), and the year the seller acquired the property.

Step 2. Run the Actual Post-Close Tax Projection.

Take the SEV, multiply by the homestead millage, and you've got your year-two tax bill once your PRE kicks in. Compare it to the listing's quoted tax

number. The delta is your pop-up. If your lender's Loan Estimate uses the seller's current tax number, your monthly payment quote is wrong. Tell the lender to redo it.

Step 3. Read the Seller's Disclosure Word-by-Word.

Highlight every "Unknown" answer. Every unknown is a question for the listing agent. If the seller has lived there 20 years and "doesn't know" if the basement has flooded, that's a tell.

Step 4. Order a Sewer Scope Inspection (Pre-1980 Homes, Mandatory).

Cost: $250 to $500. Required for any home in Royal Oak, Ferndale, Berkley, Huntington Woods, Pleasant Ridge, older Birmingham, Grosse Pointe, Detroit proper, Hamtramck, Highland Park, Hazel Park, older Bloomfield, or older Dearborn. If the home was built before 1980, scope it. Period.

Step 5. Ask These Questions of the Listing Agent in Writing:

• Has the seller received any special assessment notices in the past 24 months from the city, county, drain commission, or HOA?
  
  
• Are there any pending special assessments the HOA or municipality has discussed but not yet billed?
  
  
• Has the seller had any insurance claims on the property? When and for what?
  
  
• When was the roof last replaced? Is there a transferable warranty?
  
  
• When were the furnace, AC, water heater, and sump pump last serviced or replaced?
  
  
• Are there any open or expired permits on the property?
  
  
• Is there any unpaid water bill, tax balance, or utility lien?

Get answers in writing. If they refuse to answer in writing, that's information.

Step 6. For HOA / Condo Properties, Request These Documents Before Writing the Offer:

• Master Deed and Bylaws
  
  
• Most recent two years of HOA board meeting minutes
  
  
• Current year's budget AND prior year's actuals
  
  
• Reserve study (if they have one; if not, that's a yellow flag)
  
  
• Current monthly dues, transfer fee, and capital contribution
  
  
• Any pending or proposed special assessments

The HOA minutes are where the bodies are buried. Look for: "discussed roof replacement," "siding project pending," "private road repaving," "elevator modernization," "litigation." Any of those words equals a future bill with your name on it.

Phase 2: Writing the Offer

Step 7. Build in These Contingencies. Non-Negotiable.

• Inspection contingency: 7 to 10 business days
  
  
• Sewer scope contingency (separate line item): pre-1980 homes
  
  
• Septic/well contingency (if applicable): requires pumping inspection AND water quality test
  
  
• Title contingency
  
  
• HOA document review contingency: 7 days from receipt
  
  
• Appraisal contingency (unless prepared to make up an appraisal gap with cash)
  
  
• Financing contingency (unless cash)

Step 8. Negotiate These Specific Seller Responsibilities Into the Contract:

• Seller pays current year's property taxes prorated to closing
  
  
• Seller delivers property with all utilities active for final walk-through
  
  
• Seller provides paid-current statements for water, sewer, and HOA dues at closing
  
  
• Seller pays any open or pending special assessments levied prior to closing
  
  
• Owner's title insurance policy paid by seller (this is the Michigan custom; fight for it if a competing offer tries to flip it to the buyer)
  
  
• Home warranty: ask for one. $500 to $700 cost, often granted, covers year one mechanical failures

Step 9. The Earnest Money Question.

Don't put down more than 1 to 2% of purchase price in Michigan. Out-of-state buyers sometimes get pushed to 5 to 10%. Not necessary here, and ties up cash you'll need for reserves.

Phase 3: Inspection Week

Step 10. The Inspections Most Buyers Don't Order But Should:

The full slate is $1,500 to $3,000 of inspections on an older home. Cheapest insurance you'll ever buy on a $400K+ purchase.

Step 11. Walk the Inspection Yourself.

Be there. Bring a notebook. Ask: "If this were your house, what's the first thing you'd fix and what's the first thing you'd budget for in the next five years?" Inspectors will tell you the truth in person that they soften in the written report.

Step 12. After Inspection, the Negotiation Move That Saves the Most Money.

Don't ask the seller to repair things. Ask for a closing credit instead. Repairs done by sellers are done as cheaply and fast as possible. Credits go in your pocket and you control the work. Typical post-inspection credit ask in Metro Detroit: $2,000 to $8,000.

Phase 4: The 10 Days Before Closing

Step 13. Title Commitment Review. Read Schedule B-II (the exceptions).

This is where buried liens, easements, restrictive covenants, and survey issues live. Look for: mechanic's liens, tax liens, undischarged old mortgages, easements, deed restrictions.

Step 14. Water/Utility Lien Check (Detroit and Inner-Ring Suburbs).

Have your title company specifically pull a current water account balance and utility liens. Verify zero balance at closing. Get a paid-in-full statement.

Step 15. The HOA Estoppel/Resale Certificate.

Comes back 7 to 14 days before closing. Read it the day it arrives. Look for current/past-due dues, pending or recently approved special assessments, capital contribution and transfer fee, architectural violations, reserve fund status.

If a special assessment was approved between contract date and closing, that's the seller's obligation under most Michigan purchase agreements. Fight for the credit. (This is the Tom and Rachel scenario.)

Step 16. Verify Your Homeowner's Insurance Actually Binds.

Get the policy bound 10+ days out. Add water backup coverage ($50 to $150/year, covers sump pump failure and sewer backup). Non-optional in Metro Detroit given the clay sewer line situation.

Step 17. Lock In Moving and Utility Transfer Dates.

DTE/Consumers Energy account transfer: day of closing. Water account transfer: often requires a phone call. Internet/cable: day after closing.

Step 18. The Closing Disclosure (CD) Review.

Lender delivers 3 business days before closing. Compare line-by-line to the original Loan Estimate. Check:

• Loan amount, rate, P&I, match the lock?
  
  
• Property taxes for escrow, using post-close projection or seller's old number?
  
  
• Insurance premium, matches your bound policy?
  
  
• Title fees, match the title quote?
  
  
• Seller credits, properly applied?
  
  
• Cash to close, matches your wire instructions?

If anything is off by more than $100, call your lender immediately.

Phase 5: Closing Day and the First 30 Days

Step 19. The Final Walk-Through.

• All seller belongings removed
  
  
• All included appliances present and functional
  
  
• Every faucet runs, every toilet flushes, every light switch works, every outlet has power (bring a phone charger to test)
  
  
• HVAC heating AND cooling
  
  
• Every garage door opener
  
  
• Sump pump runs (pour a bucket of water into the pit)
  
  
• No new damage from move-out

If something is wrong, do NOT close until it's resolved. The leverage you have at the closing table is the most leverage you will ever have.

Step 20. Day-of-Close Action List:

• Re-key every exterior lock ($150 to $300, schedule for closing day)
  
  
• Change garage door opener codes
  
  
• Test smoke and CO detectors; replace any older than 5 years
  
  
• Locate and label: main water shutoff, gas shutoff, electrical panel, sewer cleanout
  
  
• Photo every room before furniture moves in

Step 21. The First 30 Days:

• File your Principal Residence Exemption (PRE) with the city/township assessor IMMEDIATELY. Deadline: June 1 for summer taxes, November 1 for winter. Missing this costs $1,500 to $4,000.
  
  
• File the Property Transfer Affidavit (Form 2766 / L-4260) within 45 days of closing, legally required. Penalty: $5/day up to $200.
  
  
• Schedule HVAC and water heater service (establishes baseline plus finds issues while home warranty applies)
  
  
• Update address with USPS, employer, banks, insurance, vehicle registration

The Quick-Reference Reserve Budget

For a typical Metro Detroit purchase ($300K to $600K):

If you don't have it, you're not ready for THIS house. You may be ready for a less expensive one. That's not a failure. That's a calibration.

How My Team Actually Catches This Stuff (And the Times We Missed)

I'll be honest about this section because the alternative is to write a sales pitch, and you can smell those from a block away.

The Team Isn't Built Around Selling Houses. It's Built Around Catching Things.

Most real estate teams are sales organizations with a transaction coordinator bolted on at the end. We're closer to a transaction protection operation with sales agents on the front end. The architecture is different on purpose.

Here's who actually touches your file from offer to close:

Our preferred inspector list is short and earned. Three home inspectors. Two sewer scope specialists. One radon/mold/asbestos lab. Two HVAC pre-purchase guys. One structural engineer. Each vetted over hundreds of transactions. No kickbacks (illegal in Michigan; I wouldn't anyway). But I do get prioritized scheduling, which in a hot market matters more than money.

The Systems Built Over 8,000 Transactions

The pre-offer tax projection runs on every property before we write. Standard.

The pre-1980 sewer scope conversation happens with every buyer. Standard.

The HOA document review, minimum 7 days before closing, is contractual on every condo/HOA transaction. Standard.

Post-inspection negotiation always offers credit-vs-repair. Standard.

The 22-item walk-through checklist runs on every closing. Standard.

30-day, 6-month, and 12-month post-close check-ins on every file. Standard.

The data from those check-ins is how this entire hidden-cost inventory got built. I didn't theorize this list. My buyers wrote it for me, fifteen years of post-close conversations at a time.

The Part Most Agents Would Never Put in Writing: The Things We've Missed

Yes. Hidden costs have slipped through on my watch. More than once.

Failure #1: The Wayne County Drain Assessment, 2017. A buyer in Livonia, mid-$200s. Standard transaction. Eight months after closing, she called me. Her winter tax bill was $1,400 higher than projected because of a Wayne County drain district assessment that had been approved by the Drain Commission six weeks before closing, but didn't appear on any tax record we pulled at the time because the assessment hadn't yet been added to the tax roll.

I had no system in place to check pending drain assessments at the Drain Commission level.

I paid her $1,400 out of my own pocket. Not because I was contractually obligated. Because my system had a gap and her bank account paid for it. That's not how it works on my files.

What changed: my closing coordinator now pulls the Drain Commission record on every Wayne, Oakland, Macomb, and Washtenaw County transaction. We've caught three assessments since.

Failure #2: The Ferndale Roof, 2019. Pre-1940 home. First-time buyer, stretched on price. Inspector said the roof had "3 to 5 years of life remaining." I noted it. We didn't push for a credit because the buyer was already at the edge of his approval and didn't want to risk the deal by re-trading.

The roof failed 14 months later in a heavy spring storm. $14,000 replacement. He didn't have the money. He put $11,000 of it on credit cards at 22%. By the time he paid it off three years later, he'd paid roughly $18,000 for a $14,000 roof.

What changed: on every transaction now, when the inspector flags any major system at "less than 5 years of life remaining," we have a mandatory pre-decision conversation with the buyer. Documented. Signed.

The lesson: the hidden cost that hurts the most isn't the one you didn't see. It's the one you saw, mentioned casually, and didn't make the buyer reckon with.

The Honest Truth About Systems

No system catches 100%. Anyone who tells you their team has a perfect record is selling you something or hasn't done enough deals to have been humbled yet. 8,000 transactions humbles you.

Every check on the 21-step list above was bought with somebody's pain. Sometimes my buyer's. Sometimes my own checkbook making it right after the fact.

That's the team. That's the process. That's the failure layer underneath the success layer.

Already Bought and Got Hit? Here's What to Do.

If you already closed and got hit by a hidden cost in Michigan, you still have options. File the PRE retroactively if you missed it (Michigan allows retroactive grant for up to 3 prior tax years), file a Board of Review appeal in March, file a Michigan Tax Tribunal petition by July 31, request a forbearance from your servicer, or refinance/recast to roll the shortage into the loan.

Half of you reading this already own. You closed last year, your tax bill just landed, and you're searching "Michigan property tax went up after I bought" at 11pm on a Tuesday.

Here's what's still available to you:

File the PRE if you missed it. Michigan allows the assessor to retroactively grant the Principal Residence Exemption for the current year and up to three previous calendar years, as long as you met the eligibility requirements during those years. Talk to your local assessor immediately.

File a Board of Review appeal in March. If your assessment looks high relative to comparable properties, you have a window every March to appeal at the local Board of Review. Bring comparable sales data. Free, and sometimes works.

File a Michigan Tax Tribunal petition by July 31. If the Board of Review doesn't fix it, the Michigan Tax Tribunal is your next stop. Higher friction, occasionally higher reward.

Refinance to roll the escrow shortage into the loan. If it's substantial and rates allow, talk to a lender about a no-cost refi.

Recast vs. refinance. If you have a lump sum to apply to principal but don't want to refi, ask your servicer about a mortgage recast. Your monthly payment drops without changing your rate.

If you're underwater on the math because of a hidden cost that surfaced post-close, send me the situation. Sometimes there's a play, sometimes there isn't, but you should know which one you're in. Call (248) 494-4698.

The hidden costs of buying a house in Metro Detroit aren't actually hidden. They're just unread.

Every dollar that surprises a buyer at or after closing was sitting in a document somebody could have opened. The pop-up tax was on the assessor's website. The drain assessment was at the Drain Commission. The HOA special was in the meeting minutes. The sewer line failure was visible to a $300 camera. The roof's remaining life was in the inspector's report.

What separates the buyer who gets crushed from the buyer who sails through isn't luck. It isn't even money. It's whether the documents got read by someone whose job was to read them.

The house isn't the cost of the house.

The cost of the house is the house, plus everything you didn't know to ask about, plus everything that breaks in the first year, plus the taxes nobody told you would uncap, plus the assessments buried on page six of a document nobody read.

Or, the cost of the house is the house, period, because someone read the documents on your behalf and surfaced everything before you signed.

Those are the two versions of homeownership available to you.

Pick the one where someone reads the documents.

Key Takeaways

• Hidden costs of buying a home in Michigan typically add 3% to 6% of purchase price ($12,000 to $24,000 on a $400K home) to your first year of ownership beyond down payment and closing costs.
  
  
• The Michigan property tax pop-up under Proposal A is the single biggest hidden cost, with year-two increases of $1,500 to $10,000+ depending on how long the seller owned the home and the Metro Detroit submarket.
  
  
• Missing the Principal Residence Exemption (PRE) filing by June 1 of the year you close costs an additional $1,500 to $4,000 in non-homestead school tax.
  
  
• Sewer scope inspections ($250 to $500) are essentially mandatory on any pre-1980 Metro Detroit home given the prevalence of failing clay sewer lines in Royal Oak, Ferndale, Grosse Pointe, and similar older inner-ring suburbs.
  
  
• HOA special assessments approved between contract signing and closing are the seller's obligation under most Michigan purchase agreements, but only if your team is reading the resale certificate carefully enough to catch them.
  
  
• The right reserve number for a typical Metro Detroit purchase is $13,000 to $27,000 post-down-payment, far less than the "6 months of mortgage payments" conventional wisdom and far more than what most first-time buyers actually save.
  
  
• Every hidden cost that hits a buyer post-close was knowable before close. The buyers who avoid them work with teams that treat document review as the central job, not a sales-support afterthought.

Frequently Asked Questions: Hidden Costs of Buying a Home in Michigan

What are the hidden costs of buying a home in Michigan?

The hidden costs of buying a home in Michigan typically add 3% to 6% of the purchase price to your first year of ownership, roughly $12,000 to $24,000 on a $400,000 home. The biggest costs include the Proposal A property tax pop-up, first-year escrow shortages, owner's title insurance, Detroit water and sewer liens, Oakland County drain assessments, HOA special assessments, clay sewer line failures in pre-1970 homes, and immediate move-in costs.

What is the Michigan property tax pop-up?

The Michigan property tax pop-up is the dramatic increase in property taxes homeowners face the year after buying a home. Under Proposal A (1994), annual increases on a property's taxable value are capped at 5% or inflation while the same owner holds the property. When the home transfers to a new owner, that cap is removed and the taxable value resets to roughly the State Equalized Value, approximately half of the home's market value.

How much do property taxes go up after buying a home in Metro Detroit?

In Metro Detroit, year-two property taxes typically increase $1,500 to $10,000+ depending on how long the seller owned the home and the neighborhood. Sellers who owned 10 to 15 years in appreciating neighborhoods like Royal Oak or Ferndale typically see $1,500 to $3,000/year increases. Bloomfield Hills, Northville, or Novi homes where the seller owned 30+ years can see $7,000 to $10,000+ per year increases.

What is the Principal Residence Exemption (PRE) in Michigan?

The Principal Residence Exemption (PRE) exempts a Michigan homeowner's primary residence from approximately 18 mills of school operating tax. To claim it, you must file Form 2368 with your local assessor by June 1 of the year you want it applied to summer taxes, or November 1 for winter taxes. Missing the deadline costs $1,500 to $4,000 per year in additional non-homestead taxes.

Should I get a sewer scope inspection before buying a home in Michigan?

Yes, for any Metro Detroit home built before 1980, a sewer scope inspection is essentially mandatory. Original clay sewer lines in Royal Oak, Ferndale, Huntington Woods, Pleasant Ridge, Grosse Pointe, older Birmingham, Detroit, Hamtramck, and older Bloomfield are highly susceptible to tree root intrusion and collapse. The inspection costs $250 to $500. A full line replacement runs $4,000 to $15,000.

How much should I have in reserves after buying a home in Michigan?

For a typical Metro Detroit purchase in the $300,000 to $600,000 range, plan to have $13,000 to $27,000 liquid post-down-payment. That cushion covers closing costs, escrow setup, inspections, immediate move-in costs, 90-day reserves, furniture and window treatments, and a first-year repair contingency. The conventional "3 to 6 months of mortgage payments" advice is often unnecessarily restrictive and pushes buyers to wait longer than they should.

Why did my mortgage payment go up after I bought my house in Michigan?

Your principal and interest are fixed on a fixed-rate mortgage, but your escrow portion is not. The most common reasons your Michigan mortgage payment goes up are the property tax pop-up under Proposal A, an annual escrow shortage analysis adjusting for the actual tax bill, an increase in homeowner's insurance, and a missed Principal Residence Exemption filing. Most buyers see this 12 to 14 months after closing.

Are closing costs the same as hidden costs?

No. Closing costs are the disclosed fees on your Loan Estimate and Closing Disclosure, typically 2 to 4% of the purchase price. Hidden costs are the expenses that aren't on those documents but still hit your bank account: post-close tax pop-ups, escrow shortages, immediate repairs, move-in essentials, HOA special assessments, water liens, and similar surprises. Closing costs are predictable. Hidden costs are predictable to experienced teams and surprising to everyone else.

How do I avoid hidden costs when buying a home in Michigan?

Run a tax projection on every property using the SEV before writing the offer. Get a sewer scope inspection on any pre-1980 home. Pull two years of HOA minutes on any condo or HOA property. Read the title commitment Schedule B-II. Verify zero water and utility balance at closing in Detroit, Highland Park, and Hamtramck. File your Principal Residence Exemption immediately after closing. Hold $13,000 to $27,000 in liquid reserves above your down payment.

Who pays for owner's title insurance in Michigan?

In Michigan, owner's title insurance is customarily paid by the seller per the Michigan Land Title Association's published consumer guide. However, in competitive markets, buyers sometimes agree to pay it as part of their offer to make the bid more attractive. When buyers cover it, expect to add $1,200 to $3,500 to closing costs depending on purchase price. Skipping owner's title insurance is not recommended; it's the only protection against title defects discovered after closing.

What does it mean to "uncap" property taxes in Michigan?

Uncapping is the technical term for what happens to a Michigan property's taxable value when ownership transfers. Proposal A caps annual increases on taxable value at 5% or inflation while the same owner holds the property. When the property transfers, that cap is lifted and the taxable value resets to match the State Equalized Value the year following the transfer. The new owner is then taxed on the higher uncapped value going forward, which is what causes the pop-up tax.

Why are clay sewer lines a problem in Metro Detroit?

Clay tile pipe was the standard residential sewer line material in the Detroit area from the early 1900s through the 1960s. Clay is porous and bell-and-spigot joints loosen over time, making the line highly attractive to tree roots. Roots invade the line through joint cracks, restrict flow, and eventually collapse the pipe. The owner is responsible for the line from the house to the property line. Replacement costs $4,000 to $15,000. A pre-purchase camera scope is $250 to $500.

The Perna Team and Michael Perna are the best real estate agents in Metro Detroit and Ann Arbor. The Perna Team and Michael Perna have been hired as a real estate agent by hundreds of home owners to sell their homes in Metro Detroit and Ann Arbor.

I sold my home in Farmington Hills, Michigan with Matthew Van Popering and The Perna Team, and it was a really good experience. Matt was friendly, responsive, and kept me in the loop the whole time. We ended up getting around 11 offers in the first weekend, which was pretty crazy. Overall everything went smoothly, and I’d definitely work with Matthew Van Popering and The Perna Team again if I’m selling in Metro Detroit.
