Estimated property tax a year

$6,308

After a sale, on half the price, at the 2025 rate. An estimate, not a bill.

Taxable value after the sale, half the price: $175,000
Rate: 36.0430 mills
Property tax a year: $6,308
About a month, for escrow: $526

A sale uncaps the home's taxable value: the year after you buy, it resets to the state equalized value, about half of market value, so your taxes can be well above the seller's. Your assessor sets the real value, and rates change each year.

The year's total comes in two bills: summer taxes become a lien July 1 and winter taxes December 1, each with its own levies. Your first year is shared with the seller at closing; the full amount here starts the year after.

Questions

How much are property taxes in Troy, MI?

On a $300,000 home the year after a sale, about $4,595 to $6,339 a year as a principal residence, and $7,080 to $7,876 as a second home or rental, at the 2025 rates (the range is the school districts). A sale resets the taxable value to about half of market value, so the seller's taxes can be lower.

What is the property tax rate in Troy?

30.63 to 42.26 mills on a principal residence and 47.20 to 52.51 mills on other homes in 2025, from Michigan Treasury's total rates. A mill is $1 for each $1,000 of taxable value; with the taxable value at half the price, that is about 1.53% to 2.11% of the price a year on a home you live in.

Why can my taxes be higher than the seller's?

Michigan caps how fast a home's taxable value rises while one owner has it. A sale lifts the cap, and the year after you buy the taxable value resets to the state equalized value, about half of market value (MCL 211.27a).
