Fixed-rate mortgage rates fell again in September.

It was the third consecutive month that rates have fallen, the Federal Home Loan Bank Board reported. The FHLBB said conventional, fixed-rate mortgages averaged 10.50% in early September, down from 10.84% the month before. Fixed-rate mortgages, which averaged 12.65% a year ago, hit a low of 10.47% in May. Rates for the most common type of adjustable-rate mortgage, one that has a cap on how much rates can increase, edged down in September as well, dropping to 9.21% from 9.43% in August and 10.60% a year ago.
