Americans bought fewer existing homes in July for the second month running, and the reason is the same one that has been holding the market down for three years: the people who would normally be selling are sitting on mortgages they cannot replace.

Existing-home sales fell 1.7% to a seasonally adjusted annual rate of 4.06 million, according to National Association of Realtors data released Tuesday. Economists had expected a smaller 1% drop. Sales were still 0.7% above July 2025, and transactions for the year to date run 2.4% ahead of the same stretch last year.

The lock-in works like this. A homeowner carrying a mortgage from 2020 or 2021 who sells and buys again swaps a low fixed rate for today’s. On the same loan balance, that can add hundreds of dollars a month for the identical house. So the owner stays put, the listing never appears, and the buyer who would have purchased it has nothing to bid on.

Rates moved the wrong way again in July. The average 30-year fixed climbed to 6.54% from 6.49% in June, per Freddie Mac, and reached 6.69% by early August — its highest since July 2025 — after six straight weeks of increases tied in part to geopolitical pressures that have kept inflation elevated since February. Rates moved from 6.43% to 6.66% over the course of the month.

Supply tightened rather than loosened. Unsold inventory fell 1.9% from June to 1.54 million units, leaving 4.6 months of supply — unchanged from both the prior month and a year ago. That squeeze keeps pushing prices up: the median existing-home price hit $434,100, a 2.0% annual gain and the 37th consecutive month of year-over-year appreciation.

Regionally, the picture split cleanly. The Northeast rose 2.0% for the month with a median price of $563,800, up 5.2% from a year earlier. The South fell 3.1%, the Midwest dropped 2.0%, and the West was flat. Median prices ran $622,200 in the West, $371,700 in the South and $342,900 in the Midwest.

The most concerning number in the report is who is missing. First-time buyers made up just 29% of July transactions, down from 33% in June and well below the 40% share NAR considers healthy. Cash buyers held at 26% and investors at 14%, both slightly above June. When more than a quarter of purchases are all cash, the financed buyer is competing against people rates cannot touch.

Affordability has technically improved. NAR’s Housing Affordability Index rose to 103.3 in July from 98.3 a year earlier, with gains in all four regions and the West leading at 7.3% — a reading above 100 means a household earning the median income can qualify for a mortgage on the median-priced home. But pending home sales posted their steepest monthly drop of 2026, and those affordability gains have not converted into transactions.

NAR chief economist Lawrence Yun called sales remarkably stable given where rates have gone, and said the market would be thriving if rates returned near 6%. He noted that in smaller Midwest cities, a $60,000 household income is enough to qualify for a median-priced home — a threshold that does not exist on the coasts. Freddie Mac’s Sam Khater said improving inventory and slightly lower listing prices suggest the market is beginning to adjust.

Homes took 29 days to sell on average, up from 28 in June. Single-family sales ran at 3.69 million with a median of $440,300, while condos and co-ops held flat at 370,000 with a median of $371,800.

For brokers, lenders and homebuilders, the read-through is that volume recovery is now hostage to a single variable. Nothing in the July data suggests demand has collapsed — it suggests transactions are being rationed by the rate spread between existing mortgages and new ones. Sales are still marginally ahead of last year on the strength of the Midwest and West. That gap closes only when rates fall enough to make moving rational again, or when enough time passes that the cheap mortgages age out of the market.
