July 12 (Bloomberg) -- Mortgage foreclosures in the U.S. jumped to a record in the first half as rising interest rates and falling home prices battered homeowners.

Almost 926,000 foreclosure notices were filed, 56 percent more than a year earlier and the most since Irvine, California- based RealtyTrac started tracking the data in 2005. Foreclosures were the highest last month in California and Florida, where some home prices have fallen as much as 25 percent, and Ohio and Michigan, where the automotive industry fired more than 50,000 people in the past 10 years.
