Mortgage Apps Fall 1.5% as Rates Hit 7.12 Percent
MBA data shows purchase applications declining while single-family inventory rises 3.2 percent year-over-year.
Key points
- Mortgage applications dropped 1.5 percent in the week ending September 18, 2026, with fixed rates at 7.12 percent.
- Active single-family inventory increased 3.2 percent year-over-year, while the median list price fell 1 percent.
- The refinance index is 62 percent lower than the same week last year, marking the slowest pace since February 2025.
Mortgage applications fell 1.5 percent in the week ending September 18, 2026. The Mortgage Bankers Association reported this drop despite a holiday adjustment in prior data. Fixed rates now sit at 7.12 percent, their highest level since May 2024. This rate spike directly suppressed borrower activity across both purchase and refinance categories.
The Market Composite Index decreased 1.5 percent on a seasonally adjusted basis. The unadjusted index showed a 9 percent increase compared to the previous week. However, the seasonally adjusted Purchase Index declined by 1 percent. This indicates that underlying demand remains weak even when accounting for seasonal factors. The refinance index dropped 3 percent and is now 62 percent lower than a year ago.
Rising rates shift borrower preference
Borrowers are increasingly choosing adjustable rate mortgages over fixed options. The ARM share reached 9.8 percent as 5/1 ARM rates lagged fixed rates by over a point. Mike Fratantoni, MBA’s Chief Economist, noted that refinancing has slowed to its lowest pace since February 2025. This shift reflects a direct reaction to the high cost of fixed-rate borrowing.
The refinance index has reached historically low levels since 1990. This decline correlates strongly with the recent increase in mortgage rates. The data shows a clear inverse relationship between rate levels and application volume. Borrowers are waiting for rates to drop before committing to long-term debt.
Inventory growth outpaces demand
Active single-family inventory rose 3.2 percent compared to the same week in 2025. This figure represents a slowdown from the previous week’s 1.5 percent increase. However, inventory remains 6.7 percent below the level seen in the same week of 2019. The data comes from Altos Research and covers activity through September 18, 2026.
The median list price is down 1 percent year-over-year. Prices have remained mostly unchanged for the last four years aside from seasonal swings. With demand weak and inventory rising, existing home sales are likely to slow. House prices will face downward pressure as the supply-demand balance shifts against sellers.
Market outlook faces pricing pressure
High mortgage rates continue to weigh on transaction volume. The combination of rising inventory and weak applications creates a challenging environment for sellers. The 30-year fixed rate above 7 percent acts as a barrier for many buyers. This structural shift suggests a prolonged period of reduced sales activity in the housing market.
The data from substack.com highlights a critical divergence in housing trends. Inventory is picking up slightly while demand remains depressed. This dynamic sets the stage for potential price adjustments in the coming months. Market participants must now account for a slower pace of existing home sales.
