What the difference costs over time

Held for 10 years, that gap compounds to $15,122 at today's rates on a $350,000 home — before any millage change. At $250,000 the annual difference is $1,080; at $500,000 it is $2,160. The gap scales with price, so it matters more at the top of each city's market than at the bottom.

Choosing the district can matter more than choosing the city. Inside Brockway Township alone the homestead rate runs 28.6411 to 29.7357 mills — a $192 annual swing on a $350,000 home, narrower than the $1,512 gap between the two cities. Two houses on the same street can sit either side of that line.

All figures use each city's lowest homestead rate at the uncapped taxable value — roughly half the purchase price — from the Michigan Department of Treasury's 2025 Total Rates report. A non-homestead property adds about 18 mills on top in either city.
