US mortgage applications declined 4.2% for the week ending Oct. 2 as rising borrowing costs reduced demand nationwide, according to the Mortgage Bankers Association’s (MBA) seasonally adjusted survey. The upward pressure on interest rates affected both home purchase and refinancing activity across the housing market.
The Federal Home Loan Mortgage Corporation, known as Freddie Mac, reported a weekly average 30-year fixed mortgage rate of 7.4% on Thursday, marking an increase of 0.12 percentage points from the previous week and hitting the highest level since November 2023. Other major lender surveys, such as Bankrate, placed national averages even higher at 7.55%.

Refinancing Activity and Purchase Demand Retreat
Higher interest rates have heavily penalized both prospective homebuyers and current homeowners looking to restructure existing loans. According to Joel Kan, the MBA’s vice president and deputy chief economist, mortgage rates moved to their highest level in almost three years, pushing many potential borrowers to the sidelines.
The association’s refinancing index dropped 8% for the week and stood 56% lower than the same week one year ago. Because millions of homeowners secured low rates during the pandemic era, replacing a 3% or 4% loan with financing above 7% creates a higher monthly interest bill, leaving very few borrowers with an incentive to refinance.
Meanwhile, applications for a mortgage to purchase a single-family home decreased 2% for the week and were 15% lower than the same week one year ago. FHA purchase applications saw sharper pullbacks, declining 6%, as escalating monthly payments compounded ongoing affordability challenges for buyers with smaller down payments.
The Shift Toward Adjustable-Rate Mortgages
To cope with steep borrowing costs, a growing share of buyers are utilizing adjustable-rate mortgages (ARMs) to lower their initial monthly payments. ARMs accounted for 10.3% of total mortgage applications, up significantly from less than 3% during the record-low fixed-rate period of the early pandemic.
- Initial Savings: A 5/1 ARM offered an average initial rate of 6.43% to 6.46%, providing a distinct monthly discount compared to fixed options above 7%.
- Budget Relief: On a standard home purchase, opting for an ARM can temporarily reduce monthly principal and interest payments by hundreds of dollars.
- Potential Risks: Economists caution that adjustable rates can reset higher after their fixed terms, increasing long-term budget exposure for borrowers if market benchmarks rise.
Broader Economic Factors Driving Rate Increases
Mortgage rates do not track the Federal Reserve’s federal funds rate point for point, but rather respond closely to yields on the 10-year Treasury note and mortgage-backed securities. Persistent inflation concerns, shifting fiscal policies, and broader bond market selloffs have driven Treasury yields higher throughout the autumn.
In mid-September, the Federal Open Market Committee raised its target range for the federal funds rate by 0.25 percentage points to 3.75-4.00% to combat continued inflation. While the move did not mechanically mandate higher housing loans, it signaled that borrowing costs would remain elevated, impacting expectations across the bond market.
For households shopping near the edge of lender approvals, the combined weight of high home prices and 7.5% mortgage rates continues to reduce purchasing power. Industry analysts note that sustained rate pressures will keep affordability tight until bond yields experience a meaningful retreat.
