The pace at which people fell behind on their mortgages slowed during the summer for the third consecutive quarter, but the overall delinquency rate hit another record, a new report shows.

For the three months ended Sept. 30, 6.25 percent of U.S. mortgage loans were 60 or more days past due, according to credit reporting agency TransUnion. That's up 58 percent from 3.96 percent a year ago.
