About Constantine Township
Two things are worth knowing before you buy. Lake homes in this county can carry managed lake levels and lake special assessments. And most homes outside the village rely on a private well and septic system, which are worth inspecting before closing. The notes below cover both.
A township-specific cost to check: special assessments can sit on top of regular property taxes. See the note below.
A property-tax timing note: most Michigan communities send separate summer and winter property-tax bills. See the note below.

Where is the house?
Pick the county, city or township, and school district. We use the official 2025 tax rates published by Michigan Treasury.
Not sure of the school district? Check the property listing. It is usually under "Schools."
Need to double-check the exact parcel? Use the official state estimator at treas-secure.state.mi.us/ptestimator or call the local treasurer. Rates can change across city, township, village, and school district lines, so the exact parcel matters.
What buyers in Constantine Township should know
Michigan property taxes start with Taxable Value, not the price you paid for the home. Local millage rates are applied to that number.
While the same owner keeps the home, Proposal A caps how much Taxable Value can rise each year. When the home sells, that cap usually comes off. This is called uncapping.
After uncapping, the buyer's Taxable Value usually moves closer to State Equalized Value, or SEV. SEV is often about half of the home's market value.
Bottom line: a longtime owner may have been taxed on an older, capped number. After you buy, the taxable number may reset higher, and your first full-year tax bill may be much higher than the seller's.
In Constantine Township, your rate can vary by parcel. The school district tied to the property matters, and 4 school districts cover Constantine Township.
For a primary home with PRE, Michigan's main-home exemption, rates currently run about 26 to 38.5 mills. Without PRE, non-homestead rates run about 44 to 56.5 mills. The calculator uses the exact local rates.
If this will be your main home, make sure the Principal Residence Exemption, or PRE, is handled with the local assessor. PRE is Michigan's main-home property tax exemption. It can remove up to 18 school operating mills. Rentals, vacation homes, and second homes usually use the non-homestead rate instead.

Is this an exact number? +
No. It is a strong estimate based on Michigan's published 2025 tax rates for your area. Your actual bill depends on what the local assessor decides your home is worth, called the SEV. Use this to plan your budget, not to lock in an exact figure.
When will my higher tax kick in? +
The first calendar year after you close. Close in June 2026, and the seller's tax bill usually comes through for 2026. Your new popped-up bill arrives in 2027.
What's PRE? +
PRE is Michigan's primary-home tax break. If you own the home and live there as your main home, it can remove up to 18 mills of local school operating tax from the bill. Rentals, vacation homes, and second homes do not get it. File Form 2368 with the local assessor by June 1 for the summer bill or November 1 for the winter bill.
What are mills? +
Mills are the tax rate. One mill means $1 of tax for every $1,000 of Taxable Value. A 40-mill rate means about $40 per $1,000 of Taxable Value. Different areas have different rates because county, city or township, school, library, public safety, parks, and other local taxes are stacked together.
What's the inflation multiplier? +
It is the yearly number Michigan uses to cap Taxable Value increases while the same owner keeps the home. Think of it as the speed limit for Taxable Value. For the 2026 tax year, the multiplier is 1.027, or 2.7%. When a home sells, that cap usually resets.
Are there ways to avoid the pop-up? +
A few, mostly family transfers. Parent to child, spouse to spouse, sibling to sibling, and some grandparent transfers may avoid the reset if the home stays residential. For family transfers, talk to a Michigan real estate attorney.
Why is my number different from the tax history on a listing? +
Most tax history pages show what the current owner paid. That is often based on a protected, lower taxable value. This calculator estimates what your taxable value becomes after Michigan's uncapping rule.
