How much are property taxes on a $350,000 home in Royal Oak Township?

Why is the tax bill on a Royal Oak Township 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.
