New single-family home sales in the US fell 0.6% month-on-month to a seasonally adjusted annual rate of 676,000 in September 2026, down from a revised eight-month high of 680,000 in August but comfortably above market expectations of 650,000. The data point to continued housing market challenges as elevated mortgage rates and rising inflation weigh on affordability, while the Federal Reserve’s latest interest rate hike adds to borrowing costs. Regionally, sales declined sharply in the South (-6.6% to 413,000) and the Midwest (-7.3% to 89,000), while rising in the West (21.4% to 142,000) and the Northeast (28.0% to 32,000). The supply of new homes for sale fell to 476,000, equivalent to 8.4 months of supply at the current sales pace. Meanwhile, the median sales price edged up to $400,400, its highest level in three months.
