If you want to see exactly what Detroit has been facing regarding its housing crisis, take a look at this incredible mosaic compiled by The New York Times using Google Maps Street View (see here).
As you scroll down the mosaic, the program tallies up the number of homes subject to foreclosure, as well as the mounting arrears on the homes. The houses appear by neighborhood. As noted, the images with the yellow triangles in the corner are still in trouble and possible on the way to public auction.
