Common questions

What is the property tax rate in Walled Lake, Michigan?

Walled Lake is taxed at 40.9991 mills for a homestead (principal residence) under the official 2025 Michigan Department of Treasury millage report. On a $350,000 home at the uncapped taxable value that is about $7,175 a year.

Does the tax rate change by address within Walled Lake?

No. All of Walled Lake sits in Walled Lake Consolidated Schools, so the millage is 40.9991 at every address in the municipality. Your bill still changes after you buy, because it is recalculated on the uncapped taxable value rather than the seller's capped one.

How much are property taxes on a $350,000 home in Walled Lake?

About $7,175 a year at the homestead rate. Michigan taxes the taxable value, not the sale price, and after a sale that value uncaps to roughly half what you paid — so $350,000 is taxed on about $175,000.

Why is the tax bill on a Walled Lake listing lower than what I would pay?

Because the figure on the listing is the seller's. Michigan caps annual taxable-value growth while an owner keeps the property, and that cap is removed the year after it sells. The longer the seller owned it, the further their bill sits below yours.

How does Walled Lake compare with the rest of Oakland County?

It is the 41 lowest of 52 municipalities in Oakland County and 169 of 236 across the eight-county region — 6.62 mills above the county median.

Is down payment assistance available for homes in Walled Lake?

Likely, but verify per program: 100% of the 117 Walled Lake sales evaluated by Down Payment Resource over the last 12 months were flagged as potentially matching at least one assistance program. The flag is an indicator, not a promise — compare the programs and check your numbers.

Why this matters: the increase hits in the tax year after your closing — so your first year looks fine and year two jumps. Lenders often escrow off the seller's old bill, which creates a shortage and a payment increase you didn't plan for.
