It was the highest since Aug. 24, 1995, when rates averaged 7.88%. Rates had fallen to 6.94% during the week ended Feb. 15--a two-year low--before they started to rise. On one-year, adjustable-rate mortgages, lenders were asking an average initial rate of 5.55%, up from 5.40% last week. Fifteen-year mortgages averaged 7.32% this week, up from 6.87% a week earlier. The rates do not include add-on fees known as points.
