Despite the Federal Reserve’s campaign to lower mortgage rates, Freddie Mac reports a jump in the 30-year fixed rate to 5.25 percent in the week ended Feb. 5 from 5.10 percent the prior week. Experts say home-loan interest is on the rise because long-term Treasury bond yields have climbed and because mortgage lenders are upping rates to ease the flood of refinancing applications.
