This interesting visualization (Created by Stamen) has appeared on the Zillow website. The map shows the breakdown by county of where exactly home loans are underwater (i.e. Negative Equity for the owner). Hover over a county and see the % of home owners in the county that are in financial trouble along with the Zillow home price index for the area. (Thanks to @Atanas for this tip via Twitter!)
With U.S. home values falling by nearly 25% since peak in 2007, many homeowners are now underwater in their mortgages, meaning they owe more than their home is worth – See the Map for yourself online HERE at Zillow
