The sale takes place all week. Properties in townships including Oak Park, Orland, Bremen and Barrington were sold Monday. Other townships, like Palatine, Rich and Hyde Park will be added on Tuesday. Delinquent taxes throughout rest of the city will be sold off Wednesday and Thursday.

Cook County Commissioner Bridget Gainer says tax sale system goes back a generation, and should be scrapped.

The owners of tens of thousands of homes and properties in Cook County who’ve fallen behind on their taxes have only a couple more days to settle their debts – or they could wind up paying a lot more.

Cook County Commissioner Bridget Gainer, 10th District, is working to build awareness about a property tax sale coming up on Monday where delinquent taxes can be sold off to private buyers, who can then charge property owners exorbitant interest rates until their debt is paid off.
