Almost one-quarter of mortgage borrowers are underwater

From The Wall Street Journal:

The proportion of U.S. homeowners who owe more on their mortgages than the properties are worth has swelled to about 23%, threatening prospects for a sustained housing recovery.

Nearly 10.7 million households had negative equity in their homes in the third quarter, according to First American CoreLogic, a real-estate information company based in Santa Ana, Calif.

These so-called underwater mortgages pose a roadblock to a housing recovery because the properties are more likely to fall into bank foreclosure and get dumped into an already saturated market. Economists from J.P. Morgan Chase & Co. said Monday they didn't expect U.S. home prices to hit bottom until early 2011, citing the prospect of oversupply.
