September 2026 data show U.S. home prices rising only 0.8% YoY while inflation outpaces gains, leaving real values lower and mortgage rates at 6.71%.
The S&P Cotality Case-Shiller U.S. National Home Price Index reached 336.663 in June 2026, up from 335.430 in May and 333.109 in April. Year-over-year growth slowed to 0.8% in April, the eleventh straight month in which real home values declined after inflation. The 20-City Composite posted a 2.3% annual gain in June, down from 2.4% in May, confirming the national slowdown.
On 3 September 2026, the 30-year fixed mortgage rate stood at 6.71% and the 15-year at 6.04%, according to FRED. The 10-year Treasury yield was 4.77%, producing a 1.94-percentage-point spread. At these levels, monthly principal-and-interest on a $400,000 loan exceeds $2,580, roughly 40% higher than the same loan at 2020 averages.
HousingWire reported that the median list price for the week ending 24 July 2026 was $449,900, down 1.8% year-over-year and 2.1% month-over-month. The 20-City Composite showed no month-over-month change in June, indicating flat prices across the largest metros. National housing starts fell 12.4% in July to 1.239 million units, the sharpest monthly drop since early 2025.
Higher-for-longer rates continue to suppress buyer demand. With inflation running near 3.8% in April, price growth below 1% translates into real declines. Inventory remains constrained, yet the combination of elevated mortgage costs and softening buyer interest has removed upward pressure on prices. Builders have responded by cutting single-family starts, further limiting new supply.
Absent a meaningful decline in the 30-year rate, price growth is expected to remain below 2% nationally for the balance of 2026. Markets with stronger job gains may see modest nominal increases, but most metros will likely post flat or slightly negative real returns.
