Why Michigan Property Tax “Uncapping” Surprises Many Greater Lansing Homebuyers
One of the most misunderstood parts of buying a home in Michigan is what happens to property taxes after closing.
Every year, many homebuyers across Greater Lansing — including Eaton, Ingham, and Clinton County — are surprised when their property taxes increase significantly after they purchase a home. Unfortunately, many buyers assume the seller’s current tax bill will remain roughly the same after the sale.
In many cases, that is not what happens.
What Is Property Tax “Uncapping” in Michigan?
Michigan’s Proposal A property tax system limits how much a homeowner’s taxable value can increase each year while they own the property. In most cases, taxable value increases are capped at the rate of inflation or 5%, whichever is lower.
That protection benefits long-term homeowners.
However, when ownership transfers to a new buyer, the property’s taxable value becomes “uncapped” the following year. The taxable value then resets closer to current market value, which can create a substantial increase in taxes for the new owner.
In simple terms:
- The seller may have owned the home for 15–25 years
- Their taxable value may have increased slowly over time
- The buyer purchases at today’s market value
- The taxable value resets after the transfer
- The buyer’s taxes often increase substantially the next year
Why This Matters to Greater Lansing Buyers
This issue affects buyers throughout the Greater Lansing region, but the impact varies depending on:
- School district millage rates
- Township versus city taxes
- Principal Residence Exemption (PRE) status
- Length of prior ownership
- Local market appreciation
For example, tax rates can differ considerably between communities in Eaton, Ingham, and Clinton Counties. Buyers moving between areas like Delta Township, East Lansing, Grand Ledge, DeWitt, Holt, Okemos, or Lansing itself may see very different future tax obligations even when home prices are similar.
Many buyers focus heavily on:
- Purchase price
- Interest rate
- Down payment
But future property taxes can significantly affect the true monthly housing cost.
A Simple Example of How Uncapping Works
Let’s say a seller purchased their home many years ago and currently has:
- Taxable Value: $90,000
- Market Value: $250,000
Because of Proposal A protections, their taxable value may have remained well below current market value.
A new buyer purchases the home for $250,000.
The following year:
- The taxable value may reset closer to the State Equalized Value (SEV)
- The SEV is generally about 50% of market value
- The taxable value could jump substantially
That means the buyer’s property taxes may increase dramatically compared to what the seller had been paying.
Why Buyers Often Miss This
Many online mortgage calculators pull current tax amounts directly from public records.
The problem?
Those taxes are based on the seller’s capped taxable value — not the buyer’s future uncapped value.
This can create a false sense of affordability.
Unfortunately, some buyers do not discover the difference until:
- Their mortgage escrow adjusts
- Their monthly payment increases
- Their first full-year tax bill arrives
What Buyers Should Do Before Purchasing
Before purchasing a home in Greater Lansing, buyers should: 
1. Ask About Current Taxable Value
Look at both:
- Assessed Value (SEV)
- Taxable Value (TV)
A large gap between the two often signals future uncapping increases.
2. Estimate Future Taxes
Michigan provides an online property tax estimator that can help buyers estimate future taxes based on uncapped values.
3. Understand PRE vs Non-PRE Taxes
A Principal Residence Exemption (PRE) can significantly reduce taxes for owner-occupied homes. Non-homestead properties are taxed at higher rates.
4. Review Local Millage Rates
Property taxes vary significantly between:
- School districts
- Townships
- Cities
- Villages
Two homes with identical prices may have very different tax obligations.
5. Build Future Taxes Into Monthly Budgeting
Buyers should evaluate the likely future payment — not just the current payment shown online.
Why This Conversation Matters
As REALTORS®, lenders, and housing professionals, our industry needs to better educate consumers about Michigan’s property tax system.
The goal is not to discourage buyers.
The goal is to help buyers make informed decisions and avoid unexpected payment increases after closing.
The more buyers understand:
- Proposal A
- Taxable value
- Uncapping
- Millage rates
- PRE exemptions
…the more prepared they will be for successful long-term homeownership.

Understanding Michigan’s uncapping rules before purchasing a home can help buyers:
