WASHINGTON (6/3/11)--Thirty- and 15-year fixed-rate mortgages slid even further during the week ended June 2, again setting new yearly low points, with 30-year loans averaging 4.55% and 15-year loans averaging 3.74%. The previous lows for this year were set last week. Freddie Mac Vice President/Chief Economist Frank Nothaft said that the fixed mortgage rate reductions related to lower weekly U.S. Treasury yields, which dropped “amid financial market concerns that the current lull in the economy is continuing.” The housing market also remains slow, he added. Five-year adjustable rate mortgages (ARM) held steady during the week, again averaging 3.41%. One-year ARMs increased slightly, totaling 3.13%. Five-year ARMs averaged 3.94% this time last year, while one-year ARMs averaged 3.95%.
