Same schools, different bill
These two municipalities share 1 school district. A school district is not a taxing unit — the city millage stacks on top — so the same classrooms can cost a different amount per year depending on which side of the municipal line the house sits.

What the difference costs over time
Held for 10 years, that gap compounds to $88 at today's rates on a $350,000 home — before any millage change. At $250,000 the annual difference is $6; at $500,000 it is $13. 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 Saint Clair Township alone the homestead rate runs 23.5755 to 29.3354 mills — a $1,008 annual swing on a $350,000 home, wider than the $9 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.
