Half of Prime Mortgages Could Go Upside Down

Half of borrowers with prime loans -- or loans made to borrowers with good credit and income -- will likely end up underwater anyway, according to a recent report.

Already more than one-third of prime mortgage loan borrowers are underwater or owe more on their homes than they're worth and with home prices expected to drop by another 10 percent, half of prime borrowers will likely end up underwater, a Fitch Ratings report found. More than 12 percent of borrowers are seriously behind on their payments according to the report, putting them at risk of defaulting.

"Prime mortgage default rates will stay elevated as home prices fall further and unemployment remains high," Fitch Ratings Managing Director Grant Bailey said in a press release.
