More than 31,000 properties are set to go up for auction in this month’s Cook County Scavenger Sale. Nearly 12,000 of them were also offered at the last three Scavenger Sales and found no buyers. [Eric Allix Rogers on Flickr]

The biennial Cook Count Scavenger Sale, when investors are invited to bid on thousands of delinquent properties, will look different this year.

But county Treasurer Maria Pappas hopes the next Scavenger Sale looks far more different.
