There is a stunning graph about foreclosures between 2005 and 2010 here. One of the pieces of info contained therein is that 23.3% of ALL mortgages are underwater. Not of sub-prime mortgages, or mortgages taken out during the boom, or mortgages in Florida, etc. That's 23.3%, or nearly a quarter, of every single mortgage in the US of A is underwater. The chart also shows that there will be over 1 million homes repossessed in the US in 2010.
