Property Tax Assessment Values Across Ann Arbor, Washtenaw County, Michigan
When examining property taxes in Ann Arbor, Michigan, understanding the distinction between "market value" and "assessed value" is crucial.

Assessment notices are sent in the spring each year and typically reach your mailbox by the middle of the season. 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.
