The average rate on a 30-year fixed mortgage in the US climbed to 6.66% as of July 30, 2026, up from 6.58% a week earlier, marking the fourth straight weekly increase. According to Freddie Mac Chief Economist Sam Khater, the housing market continues to benefit from growing inventory levels, which are giving prospective buyers more choice and helping to sustain demand despite volatile mortgage rates. One year earlier, the average 30-year fixed mortgage rate was 6.72%. Over the same period, the average rate on a 15-year fixed mortgage rose to 6.04% from 5.96% the prior week.
