Mortgage interest rates dipped again ever-so-slightly to record lows. Freddie Mac, just one of several national surveys that tracks rates, said that the 30-year fixed-rate mortgage averaged 3.34 percent with an average 0.7 point for the week ending November 15, down from last week when it averaged 3.40 percent.

Last year at this time it averaged 4 percent. The 15-year average was down, too, falling to 2.65 percent with an average 0.7 point from 2.69 percent last week.

A year ago it averaged 3.31 percent. Frank Nothaft, Freddie's vice president and chief economist, attributed the declines to indicators of higher consumer confidence and lower wholesale prices. He cited a report from the University of Michigan that shows Consumer sentiment rising in November to the highest reading since July 2007.
