Freddie Mac says that the average rate of a 30-year fixed-rate mortgage dropped to 4.44% in the week ending Aug. 12, down from 4.49% the previous week and from 5.29% the same period last year. The government-sponsored enterprise stated this was the lowest rate since it began compiling its 30-year fixed-rate survey in 1971.
