If Deutsche Bank analysts are correct, nearly half of all mortgage holders will end up underwater: [Hat tip CPGone!]

Aug. 5 (Bloomberg) — Almost half of U.S. homeowners with a mortgage are likely to owe more than their properties are worth before the housing recession ends, Deutsche Bank AG said.

The percentage of “underwater” loans may rise to 48 percent, or 25 million homes, as prices drop through the first quarter of 2011, Karen Weaver and Ying Shen, analysts in New York at Deutsche Bank, wrote in a report today.

As of March 31, the share of homes mortgaged for more than their value was 26 percent, or about 14 million properties, according to Deutsche Bank. Further deterioration will depress consumer spending and boost defaults by borrowers who face unemployment, divorce, disability or other financial challenges, the securitization analysts said.

“Borrowers may also ‘ruthlessly’ or strategically default even without such life events,” they wrote.

The analysts believe that this will cause values to drop another 14% on average, but I suspect that is a conservative estimate for such massive losses.  The bottom is still not in sight.
