Property Tax Assessment Values Across Troy, Oakland County, Michigan

When examining property taxes in Troy, Michigan, understanding the distinction between "market value" and "assessed value" is crucial.

The market value is what a willing buyer would pay to a willing seller in an open and competitive market, often influenced by location, property condition, and economic market trends. The Oakland County tax authority estimates the market value for tax purposes.

The assessed value is the market value minus any applicable exemptions or limits determined by local laws and offerings. The tax assessed value is the figure used to calculate your property taxes or the amount multiplied by your tax rate to get your tax bill.

Assessment notices are sent in the spring each year and typically reach your mailbox by the middle of the month. Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill.

For example, the median home price in Troy is $327,050, with tax bills ranging significantly across the county. Zip code 48098 has the highest median home price at $411,020.
