Mortgage rates have stayed very affordable all year. After three weeks of trending higher, rates have once again turned lower.
The 30-year fixed-rate came in at an average of 4.28%, according to Freddie Mac's weekly survey. That's down from 4.37% last week.
Meanwhile, 15-year fixed rates, popular with homeowners refinancing their loans, were at 3.32%, down from 3.39% last week.
The rates have been in a narrow range all year, from a low of 4.23% to a high of 4.53%, as the economic recovery has failed to pick up much steam.
"Mortgage rates were down this week as real GDP was revised downwards to 2.4% growth in the fourth quarter of 2013," said Frank Nothaft, Freddie's chief economist.
Not helping the economy was some brutal winter weather, according to Keith Gumbinger, vice president of mortgage information firm HSH.com.
"For the moment, mortgage rates are holding nearer to 2014 lows than highs," he said. "As the effects of winter weather begin to wear off, and if a peaceful solution can be found to quell the unrest in the Ukraine, mortgage rates can be expected to firm up again."
Cheap mortgages are a bonanza for buyers. At 4.28 %, mortgage payments on a $200,000 loan come to just $987 a month. At a historically more normal (but still reasonable) rate of 6%, the payment would be about $1,200.
