Yes. Wixom spans 3 school districts and the rate runs from 35.8219 to 40.1017 mills depending on the district your address falls in — a difference of $749 a year on a $350,000 home. The district table above lists every rate.
About $6,269 a year at the homestead rate. Michigan taxes the taxable value, not the sale price, and after a sale that value uncaps to roughly half what you paid — so $350,000 is taxed on about $175,000.
Because the figure on the listing is the seller's. Michigan caps annual taxable-value growth while an owner keeps the property, and that cap is removed the year after it sells. The longer the seller owned it, the further their bill sits below yours.
It is the 28 lowest of 52 municipalities in Oakland County and 136 of 236 across the eight-county region — 1.44 mills above the county median.
