Mortgage Refinancing Surged in September After Rate Drop

Seattle, WA, October 16, 2025-Mortgage refinancing activity surged in September, marking the largest monthly increase since Covid-era ultra-low interest rates, reports RedFin. 

“This increase followed mortgage rates dropping below 6.5% for the first time since October 2024 in anticipation of the Federal Reserve's eventual rate cuts.

“The Mortgage Bankers Association’s (MBA) Market Composite Index, a measure of total mortgage application volume, rose 29.7% from August on a seasonally adjusted basis and was 29.6% higher than a year ago, the sharpest monthly gain since 2020.

“The average contract interest rate for 30-year fixed mortgages fell 27 basis points to 6.42%, the lowest in one year. Amid lower borrowing costs, homeowners seized the opportunity to refinance, driving a 54.2% increase in refinancing activity. Purchase applications also increased 7.7% month-over-month. Compared to a year ago, purchase and refinance applications were up 18.6% and 39.8%, respectively.”
