Coruscation

Study found that homeowners who lived within 300 feet of a foreclosed residential property experienced a drop of 1.3 percent in home value; those living 300 to 500 feet of the foreclosed home typically see a drop in value of 0.6 percent.

John P. Harding, a professor at the University of Connecticut's Center for Real Estate and Urban Economic Studies, and an author of the study, said the properties that are most affected by a foreclosure are the ones close enough to see the peeling paint, broken windows and overgrown lawns that often accompany such situations.
The worst time for immediate neighbors to sell their homes, refinance or cash out some of their home equity, Mr. Harding said, is just before the bank takes title to the property, because that is the point of greatest neglect.
