NEW YORK - September 10, 2009 - Foreclosure filings in the U.S. exceeded 300,000 for the sixth straight month as job losses that boosted the unemployment rate to a 26-year high left many homeowners unable to keep up with their mortgage payments.

A total of 358,471 properties received a default or auction notice or were seized last month, according to data provider RealtyTrac Inc. That’s up 18% from a year earlier, and down 0.5% from July, the Irvine, Kalifornia-based company said in a statement. One in 357 households received a filing.

Foreclosures rose from a year earlier as companies cut payrolls by 216,000 workers last month, boosting the U.S. jobless rate to 9.7%, according to Labor Department data released last week. The rise in unemployment is having a bigger impact than an effort by the U.S. government and banks to modify mortgages and prevent foreclosures, said Morris A. Davis, an assistant real-estate professor at the Wisconsin School of Business.

“The foreclosure numbers are largely unemployment related,” Davis, a former Federal Reserve Board economist, said in an interview. “As long as 15 million Amerikans are unemployed, record foreclosures will continue.”
