the buyer's first full-year bill, once the cap comes off
$162,500 taxable × 38 mills ÷ 1,000
Assessed value taken as half of the purchase price, and one millage rate applied to both figures. A real bill also turns on the Principal Residence Exemption and on summer and winter levies being set separately, which is exactly why this is worth walking a buyer through before they sign rather than after.

The simple version of the arithmetic, with its assumptions printed under the result. It is not advice, and the point is to have the conversation before closing rather than after the first statement. The filings that follow a transfer are explained in the Property Transfer Affidavit post.
