This map of foreclosures is the best thing since sliced bread once you figure out how to navigate it. It starts off showing you a color coded map of the US showing which parts of the country are having the most problems with real estate foreclosures. But you can pick what ever part of country you want and zoom in on it. You can zoom all the way down to the township level and the map will still be color coded. I had expected it to stop at the county level.

Plus, you can see all the individual house that are in foreclosure if you zoom in fare enough.
