The average rate on a 30-year fixed mortgage backed by Freddie Mac rose by 4 bps from the previous week to 6.3% as of September 25th, rebounding after four straight weeks of declines to their lowest level since early-October. “Following several weeks of decline, mortgage rates inched up this week. Housing market activity continues to hold up with purchase and refinance applications increasing by 18% and 42%, respectively, compared to the same time last year,” said Sam Khater, Freddie Mac’s chief economist.
