Is my property over-assessed in Oakland County?
You're over-assessed when the County's value is higher than what your home would actually sell for — and then you're over-paying every year until you appeal. Michigan homeowners first appeal to the local March Board of Review (your value notice gives the dates), then to the Michigan Tax Tribunal by May 31 for residential property (July 31 for commercial/industrial), per MCL §205.735a. You must protest at the local Board of Review to preserve the Tribunal appeal.
Honest null: Oakland County's assessment roll isn't onboarded into our live check yet, so we can't pull your specific over-assessment here. Compare your assessed value to recent nearby sales on the county assessor portal — if it's higher than what your home would sell for, you're over-assessed and should appeal by the deadline above.
How to appeal your Oakland County assessment — and who files it for you
Pull your current assessed value from the Oakland County assessor portal.
Find your market value — a recent sale of your home, or comparable nearby sales.
If the County's number is higher, file an appeal with the Local Board of Review → Michigan Tax Tribunal by May 31 (Tax Tribunal; March Board of Review first).
Present your comparables (and any appraisal) at the hearing.
Most owners who win use a contingency property-tax appeal firm — it costs nothing unless they cut your bill, then takes a share of the first-year saving. About 95% of over-assessed owners never appeal, so the saving is usually left on the table.
