Homestead (PRE) applies to a primary residence; non-homestead to rentals and second homes. The dollar column is the annual bill at the uncapped taxable value — half the purchase price — at the homestead rate. Boundaries are approximate at the parcel level; confirm the district for a specific address with the district or the assessor.

Usually not. Michigan caps how fast taxable value can rise while one owner holds a property, and that cap comes off the year after it sells. The listed figure is the seller's capped bill; yours is calculated on the uncapped value, roughly half the price you pay.
Set the calculator to whichever municipality you're considering — the district rate follows the municipal line, not the school boundary.
When a Michigan home changes hands, its taxable value uncaps the following year and resets to roughly half the sale price. Buyers routinely get blindsided by a bill that's thousands higher than the listing showed. Here's your actual number.
