To measure the impact of foreclosures on nearby property values, we use a database that combines data on 1997 and 1998 foreclosures with data on neighborhood characteristics and more than 9,600 single-family property transactions in Chicago in 1999. After controlling for some 40 characteristics of properties and their respective neighborhoods, we find that foreclosures of conventional single-family (one- to four-unit) loans have a significant impact on nearby property values. Our most conservative estimates indicate that each conventional foreclosure within an eighth of a mile of a single-family home results in a decline of 0.9 percent in value. Cumulatively, this means that, for the entire city of Chicago, the 3,750 foreclosures that occurred in 1997 and 1998 are estimated to have reduced nearby property values by more than $598 million, for an average of $159,000 per foreclosure. This does not include effects on the value of condominiums, multifamily rental properties, and commercial buildings.
