One of the biggest surprises many buyers face after purchasing a home in Royal Oak, Berkley, Birmingham, Clawson, or nearby Woodward Corridor communities is learning that property taxes do not stay the same after closing.
Many buyers look at the seller’s current tax bill and assume that amount reflects what they will owe.
But in Michigan, that is not how it works.
When ownership transfers, property taxes uncap — and that can significantly change what a buyer’s future monthly payment looks like.
Lisa A. Mills with Signature by Lisa helps buyers understand this before they make an offer, so there are no financial surprises after closing.
What “Cap” and “Uncap” Actually Mean in Michigan Property Taxes
Michigan property taxes follow rules many buyers — and even longtime homeowners — do not fully understand.
Under Michigan Proposal A, while someone owns a home, the property’s taxable value is capped.
That means each year, taxable value can only increase by:
• the rate of inflation, or
• 5%, whichever is less
Even if the home’s market value rises much faster, taxable value remains limited under that cap.
This is why longtime homeowners often pay surprisingly low property taxes compared to newer buyers.
When the home is sold, that capped taxable value resets.
That reset is called:
uncapping.
After uncapping, the taxable value adjusts to current assessed market value, which can create a significant tax increase for the new owner.
Why Buyers Often Misunderstand What They Will Actually Pay
Online listing sites often display current tax records based on the seller’s ownership history.
Those numbers can be misleading because they reflect capped taxes from prior years — not post-sale reassessed taxes.
A buyer may think:
“This home’s taxes are only $4,200 annually.”
But after uncapping:
that amount may become significantly higher.
Without understanding this change, buyers may underestimate:
• monthly housing costs
• escrow requirements
• long-term affordability
This is especially important in cities like Royal Oak and Berkley where appreciation has pushed values upward.
Why Older Homeowners Often Pay Less Than New Buyers
One of my younger buyers recently experienced this confusion while writing offers in Royal Oak.
Her mother was shocked that the estimated taxes on a smaller older Royal Oak home were projected to be much higher than the taxes she and her husband pay on their larger newer home in Rochester.
But the reason was simple:
Her parents purchased their home in the early 2000s and have owned it for many years.
Because their taxable value has remained capped over time, their taxes have risen slowly and gradually.
A newly purchased home resets that cap entirely.
So even if the Royal Oak home is smaller, the buyer’s taxes after uncapping may still be much higher.
That is why comparing tax bills between longtime owners and new buyers can be misleading.
How Property Taxes Affect Monthly Mortgage Payments
When taxes increase after uncapping, mortgage payments often rise too.
That happens because escrow accounts collect monthly funds for:
• property taxes
• homeowners insurance
If taxes increase:
the lender recalculates escrow requirements.
That can lead to:
• higher monthly mortgage payments
• escrow shortages in year two
• unexpected payment adjustments
This is often when buyers first realize taxes changed.
A Field Example: How I Help Buyers Understand Taxes Before They Make an Offer
When I represent buyers in Royal Oak and Berkley, one of the most important conversations we have before submitting an offer is about future property taxes.
In Michigan, property taxes uncap after a home changes ownership, which means the seller’s current tax bill will not remain the same for the new buyer.
That matters because buyers often look at the current tax amount online and assume that number reflects what they will pay — when in reality, their future tax obligation may be significantly higher.
To help buyers plan accurately, I either:
• contact the municipality directly to request estimated reassessed tax projections, or
• use a Michigan property tax estimator tool to calculate likely post-sale taxes
This gives my buyers a clearer understanding of what their true monthly payment may look like after closing, so they can decide before offering whether that payment fits comfortably into their lifestyle and financial goals.
That clarity helps buyers make stronger, smarter decisions — and prevents costly surprises later.
What Buyers Should Ask Before Purchasing a Home
Before making an offer, buyers should ask:
• What are the current annual taxes?
• What will taxes likely be after uncapping?
• How will reassessed taxes affect monthly payments?
• Can my lender estimate escrow changes?
These questions should happen before an offer is written — not after closing.
The goal is to understand true affordability upfront.

Frequently Asked Questions About Property Taxes After Buying a Home
Do Michigan property taxes always uncap after a home sale?
Yes — in most standard sales, property taxes uncap when ownership transfers, unless a specific legal exemption applies.
What is the difference between capped and uncapped taxes?
Capped taxes are limited annual increases while the same owner holds title. Uncapped taxes reset taxable value after a sale.
Why are seller taxes lower than buyer taxes?
Because seller taxable value may have been capped for years, while buyer taxable value resets after transfer.
When will buyers notice tax increases?
Often in the first full tax cycle after purchase, or when escrow accounts adjust the following year.
Can buyers estimate taxes before buying?
Yes. Municipal estimates and Michigan tax calculators can help project likely reassessed taxes before purchase.
