WASHINGTON — Average U.S. rates for 30-year and 15-year fixed mortgages fell to record lows for the third straight week. The steady decline has made home-buying and refinancing more affordable than ever for those who can qualify.
Mortgage buyer Freddie Mac says the rate on the 30-year loan dipped to 3.79 percent. That’s down from 3.83 percent last week and the lowest since long-term mortgages began in the 1950s.
The 15-year mortgage, a popular option for refinancing, declined to 3.04 percent. That’s down from last week’s previous record of 3.05 percent.
Rates on the 30-year loan have been below 4 percent since early December. But so far, those cheap rates haven’t been enough to ignite home sales.
While sales of previously occupied homes picked up in January and February, they fell again in March and remain well below healthy levels.
Low mortgage rates have helped boost builder confidence, which rose in May to a five-year high. And home construction has improved in the past six months, a reflection of that increase in confidence.
Builders broke ground in April at a seasonally adjusted annual pace of 717,000 homes, the government reported Wednesday. That nearly matches January’s pace, the best since October 2008.
Construction rose for both single-family homes and apartments. And builders requested more permits to build single-family homes.
Mortgage rates are lower because they tend to track the yield on the 10-year Treasury note. Slower U.S. job growth and uncertainty about how Europe will resolve its debt crisis have led investors to buy more Treasurys, which are considered safe investments. As demand for Treasurys increases, the yield falls.
