Treating the listing's tax figure as their future payment
The most common mistake. Whatever Zillow or the MLS shows is the current owner's bill, not a projection for a new buyer. Always run your own estimate.

Buyer Education · Michigan Real EstateWhy the seller's taxes are not yours, and everything else you need to understand before you make an offer.
Of all the questions I get from buyers across Southeast Michigan, one comes up more consistently than almost any other: "Are the taxes on the listing what I'll actually pay?"
When buyers are deep in the excitement of finding the right home, property taxes can feel like a detail to worry about later. They should not be. Property taxes are a permanent, recurring cost that follows you for as long as you own the home. They are not a closing-day line item you pay once. They show up twice a year, every year, and in many Southeast Michigan communities they are a significant number.
The difference between a well-understood tax estimate and a surprised buyer who "didn't know it would be this much" can mean thousands of dollars annually. Over the first five years of ownership, that difference compounds into a very real budget impact. And unlike a mortgage rate, which you can sometimes refinance, your property taxes are reset by local government decisions and state formulas you cannot control after the fact.
Understanding how Michigan property taxes work before you make an offer is not optional housekeeping. It is part of making an informed decision about what any given home actually costs to own.
Property tax rates vary significantly between Wayne County, Oakland County, Washtenaw County, and Livingston County, and within each county, between individual cities, townships, and school districts. Two homes with similar list prices in different communities can have very different annual tax bills. We walk buyers through this before they fall in love with a specific address.
This is the single most misunderstood aspect of Michigan real estate, and it surprises buyers at every price point. When you look at a listing and see the current property taxes listed, whether on Zillow, Redfin, or right on the MLS sheet, you are looking at what the current owner pays based on their history with the home. That number has almost nothing to do with what you will pay.
Here is why. Michigan property taxes are calculated based on a number called taxable value. For owners who have held a home for many years, that taxable value has been growing slowly, capped by state law at no more than the rate of inflation or 5%, whichever is lower, each year. The longer someone owns a home without selling, the further their taxable value can drift below the actual market value of the home.
The moment the home sells, that cap is removed. The taxable value "uncaps" and resets to a higher number based on the current market value. The new owner (you) pays taxes on that higher number starting the following tax year.
A seller bought their Plymouth home 18 years ago. Over those years their taxable value increased slowly, capped each year. Today their taxable value sits at $148,000 and they pay roughly $4,200 per year in property taxes.
The home is listed at $380,000. You make an offer and go under contract at $375,000.
That difference is not a mistake. It is not the seller's fault. It is how Michigan's system works, and it is exactly why we run this estimate before any client makes an offer.
The taxes on the listing are the seller's taxes. Your taxes are a completely different calculation, and they start the year after you close.
Michigan property tax statements show three different value figures, and buyers who have not seen one before are often confused about which number actually matters. Here they are, in plain English.
Assessed Value (AV) is the local assessor's estimate of what your property is worth, by law set at 50% of estimated market value. If your home is worth $350,000 on the open market, the assessor is supposed to assess it at $175,000. This is not the number you pay taxes on, but it is the starting point.
State Equalized Value (SEV) is the county-equalized version of assessed value. After each local assessor sets their assessed values, the county reviews them and may adjust them up or down to ensure consistency across townships and cities. In most cases, SEV equals the assessed value, and for most buyers in Southeast Michigan you can treat AV and SEV as the same number. When a property sells, the new taxable value in the following year resets to the SEV.
Taxable Value (TV) is the number you actually pay taxes on. It is your taxes-due multiplier. For a recent buyer, taxable value equals SEV; they reset together at the point of sale. For a long-time owner, taxable value is often significantly lower than SEV because of the annual Proposal A cap described in the next section.
When you see a tax bill, the math is simple: Taxable Value ÷ 1,000 × Total Millage Rate = Annual Tax Bill. That is the formula. Everything else is just understanding what goes into each of those inputs.
Assessed Value = SEV in most cases (50% of market value estimate)
Taxable Value = what you actually pay taxes on
For a new buyer: Taxable Value = SEV at the time of sale
For a long-term owner: Taxable Value is often well below SEV due to the annual cap
In 1994, Michigan voters passed Proposal A, which changed the way property taxes work. One of its key features was a cap on how fast the taxable value of a property could grow each year. Under Proposal A, a property's taxable value can increase by no more than 5% or the rate of inflation, whichever is lower, from one year to the next, as long as the property has not changed ownership.
This was good news for existing homeowners. In a rising market, their tax bills grew slowly even as home values climbed. A homeowner who bought in 2002 and held through the run-up to 2024 might have seen their home's market value triple while their taxable value only doubled, meaning their taxes grew significantly slower than their home's equity.
The trade-off is what happens when the home sells. When ownership transfers, the cap is removed and the taxable value "uncaps." It resets to the SEV, the full 50%-of-market-value figure, in the tax year following the sale. The new owner pays taxes on that higher, uncapped value from their first full year of ownership onward, until their own annual cap kicks in and begins protecting them going forward.
This is not a penalty for buying a home. It is simply how the system resets at each transfer. The longer the previous owner held the property, the larger the potential gap between their old taxable value and your new one, and the larger the increase in the tax bill you should expect.
For a focused walkthrough with examples and a buyer checklist, see our Taxable Value Uncapping Guide.
Sellers who have owned their home for 15 to 25+ years often have taxable values far below current market conditions. In some cases the gap between the seller's taxable value and the post-sale reset can be $100,000 or more on a home worth $350,000 to $450,000. The annual tax difference on a $100,000 taxable value gap at a 40-mill rate is $4,000 per year. That is a real number that belongs in your buying decision.
The Principal Residence Exemption, often called the PRE or the homestead exemption, is the most valuable tax benefit available to Michigan homeowners, and it is one that buyers need to understand and act on immediately after closing.
Here is how it works. Michigan school districts levy what are called "operating millages": taxes that fund school operations. If you own a property and live in it as your primary residence, you are exempt from up to 18 mills of those school operating taxes. If you own an investment property, vacation home, or rental, you are not exempt; you pay the full school operating millage. That difference, depending on the community and the home value, can be several hundred to several thousand dollars per year.
To receive the PRE, you must file a Principal Residence Exemption affidavit with your local assessor's office. This is a simple form, but it is time-sensitive. The filing deadline for the exemption to affect your summer tax bill is June 1. Filing by November 1 captures it for the following year's bills. File late and you forfeit the savings for that tax cycle. There is no retroactive catch-up.
In practice: close on your home, celebrate, and then file your PRE within the first few weeks. Most closing attorneys or title companies mention this at the table, but I make a point of reminding every buyer I work with because the stakes are real.
Our dedicated PRE / Homestead Exemption Guide covers filing deadlines, former-rental scenarios, and post-closing steps in detail.
If the home you are buying was a rental, a second home, or had lapsed PRE status, the tax records may show a higher-than-homestead bill. Once you close and file your own PRE as an owner-occupant, the 18-mill exemption applies going forward. The uncapping still happens at the time of sale regardless of the previous PRE status, those are two separate events.
We walk every Hearts to Homes buyer through the PRE process before and after closing so nothing gets missed.
Here is something that catches buyers off guard even in communities they think they know well: two homes on streets just a few blocks apart, carrying the same city name in the address, can have meaningfully different tax bills, because one is inside the city limits and one is in the surrounding township.
Cities and townships are separate governing jurisdictions in Michigan, and they levy separate millages. A home inside a city pays a city millage on top of the county millage, the school district millage, and any other local millages that apply to both. A home in the surrounding township pays a township millage, which is often lower than the city millage, without the city layer.
The City of Brighton and Brighton Township share a school district, a county, and much of the same name. But a home inside the City of Brighton pays the city's millage rate on top of Livingston County and Brighton Area Schools millages. A comparable home in Brighton Township, perhaps just a few streets outside the city limits, does not pay the city millage, resulting in a lower overall bill. If you are searching in the Brighton area specifically for the lower Livingston County tax environment, whether your address is city or township can affect the final number. We verify this for every Brighton-area search we run. You can learn more in our Brighton community guide.
The City of Plymouth and Plymouth Township are two entirely separate municipalities. Homes in the City of Plymouth pay Plymouth city millages. Homes in Plymouth Township, which surrounds and is much larger than the city, pay Plymouth Township millages, which carry a different rate. Both fall within the Plymouth-Canton Community Schools district in many cases, and both are in Wayne County, but the city vs. township distinction changes the tax bill. You can explore both in our Plymouth community guide.
Northville is one of the few Southeast Michigan communities that spans two counties: Wayne and Oakland. The county your specific Northville address falls in affects the county-level millage on your bill. Two homes in the same Northville school district, both "in Northville," can carry different county millages depending on which side of the county line they are on. This is the kind of detail that changes the annual tax estimate, and it is exactly why address-level verification matters more than ZIP code assumptions. More on Northville in our Northville community guide.
Always verify the jurisdiction (city or township) and the county for any specific address before estimating taxes. ZIP codes and community names do not tell the whole story. Millage rates are published by each municipality and can be looked up through the county's website or confirmed by the local assessor's office.

Zillow, Redfin, Realtor.com, and most MLS listing sheets display the current owner's actual tax bill pulled from public records. That number is accurate, but only for the current owner. But it has no predictive value for a new buyer, because it reflects a taxable value that may have been capped for a decade or more and will reset entirely when the home sells.
In a market with rising home values, which Southeast Michigan has experienced steadily, a home that last sold in 2005 and has been owned since might show a tax bill of $3,800 per year on a listing. A new buyer purchasing that same home for $390,000 at today's prices might find their annual tax bill closer to $7,500 after uncapping and a full-year PRE application. The listing said $3,800. The reality is $7,500. That is a $3,700 annual difference nobody mentioned.
This is not deceptive on the part of listing agents. The public record is the public record, and in many states it accurately predicts what a buyer will pay because those states do not use Michigan's capped-taxable-value system. But Michigan does, and buyers in this state need to run the calculation themselves rather than accepting the figure on the listing sheet.
The listings most likely to show a large gap between current taxes and future buyer taxes are homes that have been owned for a long time, estate sales, and homes where the taxable value is obviously low relative to the home's market value. If a $425,000 home shows annual taxes of $3,200, that is a signal worth investigating, not celebrating.
If the taxes look surprisingly low on a home you like, that is not a deal. That is a signal to run your own estimate before you fall in love with the monthly payment.
You do not need a finance degree to estimate your property taxes before making an offer. You need a purchase price, a millage rate, and about two minutes. Here is the approach we walk buyers through.
Divide the purchase price by 2 to approximate the SEV, which becomes your new taxable value in the year after closing. If you are purchasing for $340,000, your estimated new taxable value is approximately $170,000. This is an approximation. The actual SEV is set by the assessor based on their own market analysis, but for estimation purposes this calculation gets you close.
This is the one variable you cannot calculate. You have to look it up. Most county websites publish millage rates by township and city, updated annually. Your Realtor can also pull this for you or direct you to the local assessor's office. The total millage rate for any Southeast Michigan property is the sum of all applicable millages: county, city or township, school district, and any additional local millages (community college, library, and others). Total millage rates across Southeast Michigan communities typically range from about 30 to 65+ mills, with significant variation by location.
If you will live in the home as your primary residence and file for the PRE, subtract the homestead exemption from the school operating millage portion of your total. The PRE exempts up to 18 mills of school operating tax. Your Realtor or the local assessor can confirm the homestead vs. non-homestead millage rates for that specific school district.
Purchase price: $340,000
Step 1: Estimated new taxable value = $340,000 ÷ 2 = $170,000
Step 2: Assume the total homestead millage rate for this community is 42 mills.
Non-homestead rate (if not filing PRE): assume 60 mills
The PRE saves approximately $3,060 per year in this example. Filing it promptly after closing matters.
This is an estimation method, not a tax calculation. The actual SEV is set by the assessor, not derived simply from the purchase price. Millage rates change annually. The actual tax bill in your first full year of ownership may differ from this estimate. Use it as a budgeting tool and a comparison guide, not as a guaranteed number. Your Realtor or the local assessor's office can give you the most current figures for any specific address.
This is part of what we do for every buyer we work with. Send us the address and the expected offer price and we will pull the millage rate, run the estimate, and walk you through what it means for your monthly budget.
The most common mistake. Whatever Zillow or the MLS shows is the current owner's bill, not a projection for a new buyer. Always run your own estimate.
Not filing within the deadline window means paying a full non-homestead tax year. In many Southeast Michigan communities, that is $1,500 to $3,000+ in unnecessary taxes. File right after closing.
City vs. township, school district boundaries, and county lines all affect the millage rate independently. Two addresses in the same "city" can carry different rates. Verify by parcel, not by ZIP.
Lenders often use the current tax bill in DTI calculations, especially early in the process. If your post-uncapping taxes are significantly higher, your actual payment-to-income ratio changes. Discuss this with your lender early.
School district boundaries and mailing addresses are separate in Michigan. In the Brighton area, some homes carry a Brighton mailing address but fall within Pinckney, South Lyon, or Howell schools, each with a different millage. Always verify the actual school district for any specific address.
A lower tax bill in one community may simply reflect a lower home value. Compare effective tax rates, meaning taxes as a percentage of home value, not raw dollar amounts, when evaluating communities against each other.
You have done the research, made the offer, and you are heading toward the closing table. Here is the property-tax checklist we walk every Hearts to Homes buyer through in the weeks before and immediately after closing.
Your Realtor can give you a solid estimate and guide you through the PRE process. For the official millage rate, the current homestead status of a specific property, or if you want to appeal your assessed value after you take ownership, the local assessor's office is the right call. They are a public resource and generally very helpful for straightforward questions. Most assessor offices are reachable by phone or in person and can confirm specific parcel details quickly.
Property taxes in Michigan vary by municipality, school district, county, and individual property. Tax laws, millage rates, and exemption rules can change. The information in this guide is educational and intended to help buyers understand how Michigan's property tax system works in general terms. It does not constitute tax advice, legal advice, or a guarantee of any specific tax outcome. Before purchasing any property, buyers should verify all tax estimates, school district boundaries, and homestead exemption details directly with the local assessor's office or a qualified tax professional. The Hearts to Homes Team is happy to walk through estimates with you as part of the home-buying process, but all official determinations rest with the appropriate government authorities.
Under Michigan's Proposal A, property taxes are calculated on taxable value, which is capped each year for existing owners. When a property sells, the taxable value uncaps and resets to the State Equalized Value (SEV) in the following tax year. Buyers often pay significantly more in taxes than the current owner, especially if the seller has owned the home for many years and the taxable value has lagged far behind current market value.
The Principal Residence Exemption (PRE), sometimes called the homestead exemption, exempts a Michigan homeowner's primary residence from up to 18 mills of school operating taxes. It can save hundreds to over a thousand dollars annually. To receive it, you must own the property, occupy it as your primary residence, and file an affidavit with your local assessor. The deadline to affect your summer tax bill is June 1; filing by November 1 affects the following year.
Michigan's Proposal A caps annual taxable value increases at 5% or the rate of inflation, whichever is lower. This cap protects existing homeowners from rapid tax increases. When a property is sold, the cap is removed and the taxable value resets to the State Equalized Value, approximately 50% of assessed market value, in the following tax year. Buyers pay taxes on the uncapped, higher taxable value from their first full year of ownership.
Assessed Value is the local assessor's estimate, set at 50% of market value. State Equalized Value (SEV) is the county-equalized version. In most cases it equals assessed value. Taxable Value is what you actually pay taxes on. For long-time owners, taxable value is often well below SEV because of the Proposal A cap. After a sale, taxable value resets to the SEV.
Divide the purchase price by 2 to approximate the new taxable value (SEV). Multiply by the total millage rate for that address, divided by 1,000. For example: $350,000 ÷ 2 = $175,000 × 42 mills ÷ 1,000 = $7,350/year. Apply the PRE reduction if you will owner-occupy. Your Realtor or the local assessor's office can verify the millage rate for any specific address.
Often yes. City addresses carry a city millage on top of the county and school district millages that all properties in the area pay. A home inside the City of Brighton, for example, pays Brighton city millage plus the county and school district millages. A comparable home in Brighton Township pays only township millage plus the same county and school millages, without the city layer. The difference varies by community but can be meaningful annually.
Listing sites display the current owner's actual tax bill, which reflects their capped taxable value, often far below what a new buyer will pay after uncapping. If the seller bought their home 15 years ago, their taxable value may be significantly lower than the current market value. Always ask your Realtor to estimate the post-sale tax bill based on the purchase price and current millage rates.
Non-homestead properties pay a higher school operating millage because the PRE is not applied. If you purchase a former rental and will live in it as your primary residence, you can file for the PRE after closing and receive the exemption going forward. The uncapping event at sale still applies regardless of the previous homestead status.
File as soon as possible after closing, ideally within weeks of getting your keys. The filing deadline for the PRE to affect your summer tax bill is June 1. Filing by November 1 affects the following year's bill. Filing late means paying a full tax year at the higher non-homestead rate.
Yes, meaningfully. Each county has its own millage rate, and the school district and local township or city millages vary further within each county. Generally, Livingston County (Brighton, Howell, Hartland) carries lower overall millages than much of Wayne County. Oakland County varies significantly by municipality. The only accurate comparison is at the specific address level, accounting for the exact school district, jurisdiction, and county.
A millage rate is the tax rate expressed per $1,000 of taxable value. One mill equals $1 of tax per $1,000 of taxable value. Your total millage rate is the sum of all applicable millages: county, township or city, school district, library, community college, and others. Multiplying your taxable value by the total millage rate (divided by 1,000) gives your estimated annual tax bill before any exemptions.
Yes. Property owners in Michigan have the right to appeal the assessed value of their property, typically by filing with the local Board of Review in March. If you believe the assessor's valuation is too high relative to the market, an appeal is worth exploring. This is separate from the uncapping question. Consulting a local property tax professional or attorney is advisable for formal appeals.

Real estate doesn't come with a handbook, and Michigan's property tax system is genuinely one of the more complicated parts for buyers to work through, especially if you are moving from out of state or buying for the first time. If you are looking at a home and wondering what taxes will actually look like after you close, or if you want to compare two communities side by side before you commit to a search, we are happy to walk through it with you before you make an offer.
That conversation costs nothing. It takes twenty minutes. And it almost always surfaces something that matters to the final decision: a millage rate difference, a school district boundary, a city vs. township distinction that changes the monthly number by a few hundred dollars a year.
"We believe educated buyers make confident buyers. The more you understand before you make an offer, the more clearly you can see whether any given home is actually the right move for your life."
