State law in Michigan requires two annual auctions. Here’s a link to a brochure that describes property tax foreclosure in Michigan
Treasurer Andy Meisner offers delinquent taxpayers very flexible, monthly payment plans to avoid losing their property, and to ensure their debt is not shifted onto the rest of the Oakland County taxpayers.
There are two auctions of tax-foreclosed property in Oakland County. They're typically held in mid-August and mid-October. Details of the August 2015 sale will be posted several weeks prior to the auction.
