What the Grand Rapids study shows
Every Michigan community publishes the sales it used to set this year’s values. In the City of Grand Rapids 2026 neighborhood economic condition factor studies, matched to each home’s current assessment in Kent County’s parcel records, 379 of 2,211 homes that sold in 2024 and 2025 carry an assessment more than 10 percent above what the buyer paid. That is about 1 in 6. Across all of them, the typical assessment is 46 percent of the sale price, close to the 50 percent the law targets, so most buyers are assessed fairly. The ones who are not can pay hundreds or thousands of dollars a year more than they should.
Grand Rapids publishes its study by neighborhood without each home’s assessment, so we matched its sales to the current assessment in Kent County’s parcel records and carried each sale price forward at 4 percent a year to the December 31, 2025 valuation date, which keeps the figure conservative. Assessments vary more from home to home here than in most cities we have checked.
One Grand Rapids sale, from the study
A Grand Rapids house that sold in March 2025 for $275,000. The study lists its assessment at $190,600, which values it at $381,200: 39 percent above the sale.
Assessor’s value
Twice the assessment in the city’s study.
$381,200
Sold for
The recorded sale, which the city’s own study counts as a valid market sale.
$275,000
Tax on the gap, per year
$1,759
Half the gap between the assessor’s value and the sale price, at the 33.12-mill homestead rate for Grand Rapids Public Schools. A gap is a reason to look, not proof the value is wrong; the house is shown without its address.
How property tax works in Grand Rapids
Your bill is figured from your taxable value. While you own a home, it can rise each year by no more than inflation or 5 percent. The year after you buy, that cap comes off and your taxable value resets to the full assessment, so a buyer’s first full bill is set by what the assessor thinks the house is worth. Assessed, state equalized and taxable value, explained.
For a primary residence in Grand Rapids Public Schools, the 2025 rate is 33.12 mills, or 3.31 percent of taxable value. Homes in the Forest Hills, Caledonia and Godwin Heights districts pay about 34 to 36 mills. At that rate, every $10,000 the assessor overstates your home’s value adds about $166 a year to your bill, and keeps adding it every year you own the home.
How to appeal in Grand Rapids
The Grand Rapids City Assessor sets values and runs the Board of Review. Your assessment notice arrives in late February and lists your assessed and taxable values, the Board of Review dates and how to book a time. You can also look up your record on the city’s online property lookup.
- March Board of Review. The only time of year to appeal the value itself. Most boards require an appointment, booked by the deadline printed on your notice.
- Bring evidence. Comparable sales, an appraisal, photographs of anything the city’s record gets wrong. A board will not lower a value on an owner’s opinion alone. That evidence is exactly what our appeal packet puts together: your home rebuilt against the city’s own study, the comparable sales that support a lower value, and the filing instructions for your board, for a flat $350.
- If the board says no, you can appeal to the Michigan Tax Tribunal’s Small Claims Division by July 31.
