According to the Mortgage Bankers Association, mortgage applications fell by 2.7% for the week ending September 4, 2026. This decline follows a modest 0.8% increase in applications for the period ending August 28.
The average 30-year fixed-rate mortgage rose to 6.85%, up from 6.79% the previous week. Freddie Mac's Primary Mortgage Market Survey reported a different average of 6.71% for the week ending September 3, marking the highest level since July 2025.
MBA economists Joel Kan and Mike Fratantoni attribute the rising rates to inflationary pressures and fluctuations in the 10-year Treasury yield. Zillow data indicates that existing home sales in August fell 0.6% year-over-year as rates stayed above 6.5% during the summer.
For a $400,000 home with a 20% down payment, the increase from a 6% to a 6.85% rate adds approximately $170 to monthly payments. Over a 30-year term, this results in more than $61,000 in additional interest payments.
The current environment has created a lock-in effect, as homeowners with pandemic-era mortgages at 3% or 4% have little incentive to sell. Both purchase and refinance activity remain volatile as rates approach the 7% threshold.
