For the first time in four weeks, average fixed mortgage rates moved lower, according to Freddie Mac’s weekly mortgage market survey. Rates remain near May 2013 lows. The lower rates are attributed to a revision down of real GDP growth and the decline in consumer prices, said Freddie Mac’s deputy chief economist Len Kiefer.
