Average fixed-rate mortgages moved lower this week, helping to keep buyer activity strong toward the close of the spring homebuying season, Freddie Mac reports in its weekly mortgage market survey.

"Mortgage rates fell as well, although not by as much as government bond yields. The rate on 30-year fixed-rate mortgages fell 4 basis points to 4.04 percent. Overseas volatility is likely to persist for some time, providing some restraint on potential U.S. rate increases." Also, Becketti notes that the minutes of the June meeting of the Federal Open Market Committee suggest the Federal Reserve will proceed cautiously -- monitoring events both overseas and in the U.S. in determining when to begin raising short-term interest rates. "As a result, mortgage rates may remain in the neighborhood of 4 percent for a while," Becketti notes. Freddie Mac reports the following national averages with mortgage rates for the week ending July 9: 30-year fixed-rate mortgages: averaged 4.04 percent, with an average 0.6 point, dropping from last week's 4.08 percent average. A year ago, 30-year rates averaged 4.15 percent. 15-year fixed-rate mortgages: averaged 3.20 percent, with an average 0.5 point, dropping from last week's 3.24 percent average. Last year at this time, 15-year rates averaged 3.24 percent. 5-year hybrid adjustable-rate mortgages: averaged 2.93 percent, with an average 0.4 point, dropping from last week's 2.99 percent average. A year ago, 5-year ARMs averaged 2.99 percent. 1-year ARMs: averaged 2.50 percent, with an average 0.3 point, dropping from last week's 2.52 percent average.
