New single-family home sales dropped to a seasonally adjusted annual rate of 580,000 units in May 2026, according to US Census Bureau data released on June 24. That’s a 7.3% decline from April and 6.8% lower than the same month last year. Meanwhile, the inventory of new homes available for sale climbed to 496,000 units, translating to a 10.3-month supply, the highest level since 2009.
The numbers tell a split story
On the new construction side, sales are falling, inventory is piling up, and the median price of a new home sits at $424,900, up 2.0% from April but essentially flat compared to a year ago. Builders are sitting on nearly half a million unsold homes with fewer buyers walking through the door each month.
The existing home market looks almost healthy. Data from the National Association of Realtors shows existing-home sales actually rose 3.2% month-over-month, hitting an annualized rate of 4.17 million units in May. Existing home inventory stands at 1.55 million units, which works out to just 4.5 months of supply.
