Mortgage rates dropped substantially Thursday, as falling oil prices and the tentative U.S.-Iran peace deal pushed long-term borrowing rates lower. The average rate on 30-year fixed home loans fell to 6.43% for the week ending July 2, down 6 basis points from 6.49% the previous week, according to Freddie Mac . For perspective, rates averaged 6.67% during the same period in 2025.
