Property taxes for a new owner
The current owner pays about $1,821 a year. A buyer who lives here would pay about $2,035 a year once the taxable value resets after the sale, at the 2025 homestead rate of 32.23 mills for Clay Twp and Algonac schools, plus the 1% administration fee. Michigan resets a home's taxable value the year after it sells, so the seller's bill isn't a good number to budget with. See the math.
