Estimated property tax a year

$7,376

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: 42.1483 mills
Property tax a year: $7,376
About a month, for escrow: $615

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.

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