The interest rate for a 30-year mortgage fell for the eighth time in nine weeks, according to a widely watched survey, with the record lows triggering the highest volume of home refinancing in 15 months.

Freddie Mac’s weekly report on lenders said solid borrowers with 20% down payments or home equity were being offered 30-year fixed-rate loans at an average of 4.42% this week, down from 4.44% a week earlier. The borrowers would have paid 0.6% of the loan amount in upfront lender fees.

The average 30-year interest rate recorded by the survey has not risen in nine weeks, although it remained flat at 4.57% for the weeks ending July 8 and July 15.

One reason is the terrible housing market. Homeowner confidence in the real estate market has dipped again.

Homeowners(i) are more pessimistic about the short-term future of home values in their local market than they have been in the past three quarters, according to the Zillow second quarter Homeowner Confidence Survey(ii). One-third (33 percent) believe home values in their local housing market have not yet reached a bottom, while 38 percent believe they have already reached a bottom.

Clearly, the foreclosure crisis has a long way to go.
