NEW YORK - April 7, 2009 - More U.S. consumers are falling behind on their mortgages, an indication that the housing market has yet to hit bottom, a top credit bureau executive told Reuters.

Dann Adams, president of U.S. Information Systems for Equifax Inc, reported that 7 percent of homeowners with mortgages were at least 30 days late on their loans in February, an increase of more than 50 percent from a year earlier.

He also said 39.8 percent of subprime borrowers were at least 30 days behind on their home mortgage loans, up 23.7 percent from last year.

"I'm trying to find optimism in these numbers, but I'm pretty hard pressed to do that," Adams said, despite a recent burst of relatively positive news that has fueled hope that the U.S. housing market has turned a corner.

Late last month, the Commerce Department reported that sales of newly built U.S. single-family homes rose to a 337,000 annual pace in February, the highest in 10 months.

Such news has boosted homebuilder shares, which are up about 45 percent since March 6, according to the Dow Jones U.S. Home Construction Index.

But Adams said the continued increase in mortgage delinquencies revealed in his data foreshadows more foreclosures, short sales and home price declines as homeowners default and banks then repossess the homes to sell them at deep discounts.
