U.S. mortgage rates climbed to their highest level in about 11 months this week, adding pressure on homebuyers as housing prices remain near record levels.

The average rate on a 30-year fixed mortgage rose to 6.58% from 6.55% a week earlier, according to Freddie Mac's latest Primary Mortgage Market Survey released Thursday.

The rate was last at 6.58% on Aug. 21, 2025, and stood at 6.74% a year ago.

The average 15-year fixed mortgage rate also increased to 5.96% from 5.93% the previous week.

It averaged 5.87% a year earlier.
