Greg writes to mention that the housing-search site HotPads also has a foreclosure heat maps layer. From the site: “HotPads Foreclosure Heat Maps portray the markets hit hardest by the recent housing crisis and the increased foreclosure rates. These foreclosure heat maps visually illustrate the foreclosures per capita and display color-coded foreclosure rates by county and state.” Greg says, “A more detailed version of the foreclosure map you posted a few days ago, this one lets you zoom down to the street level in your neighborhood.”
