11.3 million homeowners underwater on mortgage
WASHINGTON (MarketWatch) -- More than 11.3 million homeowners -- nearly one-fourth of all Americans with a mortgage -- owe more on their loan than their home is now worth, according to a report released Tuesday by FirstAmerican CoreLogic.

The number of underwater mortgages increased by about 620,000 from the third quarter, the firm said. Another 2.3 million mortgages had less than 5% equity in their home, which could be wiped out if home prices fall further.
