WASHINGTON (AP) _ The number of homeowners ensnared in the foreclosure crisis grew by more than 70 percent in the third quarter of this year compared with the same period in 2007, according to data released Thursday.

Nationwide, nearly 766,000 homes received at least one foreclosure-related notice from July through September, up 71 percent from a year earlier, said foreclosure listing service RealtyTrac Inc.

By the end of the year, RealtyTrac expects more than a million bank-owned properties to have piled up on the market, representing around a third of all properties for sale in the U.S.

RealtyTrac monitors default notices, auction sale notices and bank repossessions. More than 250,000 properties were repossessed by lenders nationwide in the third quarter, 81,000 of which were taken back last month.

Six states — California, Florida, Arizona, Ohio, Michigan and Nevada — accounted for more than 60 percent of all foreclosure activity in the quarter, with California alone making up more than a quarter of all U.S. foreclosure filings.

Detroit and Atlanta were the only cities outside California, Florida, Nevada and Arizona to make RealtyTrac's list of the 20 hardest-hit metropolitan areas.
