What is the scavenger sale?

When a property owner does not pay their property taxes for three years or more (becoming "delinquent"), the right to acquire the property from them (in the form of a delinquent tax lien) is sold to the public via a scavenger sale that is required by Illinois law.

The price is decided on via an auction, with a minimum bid of $250 (or half of the delinquent taxes+interest if that total is less than $500). The winning buyer does not have to pay the delinquent (back) taxes, but will be responsible for unpaid taxes after the sale, before they have a deed to the property.

To be clear: Winning bidders acquire a delinquent tax lien, not a property.

After the redemption period expires – during which the current owner can pay back taxes to Cook County and stop the sale – the buyer can apply to convert the tax lien to a deed. Assuming the buyer followed all of the rules, Cook County assigns the deed to the buyer.

What kinds of properties are in the sale?

More than half (58%) are vacant lots.

The next biggest group are single-detached houses (15%), followed by residential side yards (5%), and two to six-flat houses (4%). Of the remaining 18% there are nearly 800 condos and then various commercial buildings.

The redemption period is six months for vacant lots and commercial properties (7+ units, mixed use, industrial, retail, office, etc.) and 30 months for residential properties (1-6 units, condos, townhouses).
