The Effect of Foreclosures on Nearby Housing Prices: Supply or Disamenity?

A number of studies have measured negative price effects of foreclosed residential properties on nearby property sales. However, only one other study addresses which mechanism is responsible for these effects. I measure separate effects for different types of foreclosed properties and use these estimates to decompose the effects of foreclosures on nearby home prices into a component that is due to additional available housing supply and a component that is due to dis-amenity stemming from deferred maintenance or vacancy. I estimate that each extra unit of supply decreases prices within 0.05 miles by about 1.2% while the dis-amenity stemming from a foreclosed property is near zero.
