One in Four Borrowers Is Underwater

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.

Mortgage troubles are not limited to the unemployed. About 588,000 borrowers defaulted on mortgages last year even though they could afford to pay -- more than double the number in 2007, according to a study by Experian and consulting firm Oliver Wyman. "The American consumer has had a long-held taboo against walking away from the home, and this crisis seems to be eroding that," the study said.

Borrowers with negative equity are more likely to default if they live in a state where the bank can't pursue their assets in court, according to a study by the Federal Reserve Bank of Richmond.

But borrowers who are less than 20% under water are likely to maintain their mortgage if their loan is modified and the payments reduced, said Sanjiv Das, head of Citigroup's mortgage unit. "Beyond 120%, the most effective modification is a complete loan restructuring, including a principal reduction."

Mortgage companies have been reluctant to reduce mortgage principal over worries about "moral contagion, with people not paying their mortgage or redefaulting because they believed the bank would reduce their principal," Mr. Das said.
