The May numbers
Sales of new single-family houses ran at a seasonally adjusted annual rate of 580,000 in May 2026, Census and HUD reported on June 24. That was 7.3 percent below April's 626,000 and 6.8 percent below the May 2025 rate of 622,000. Both comparisons carried confidence intervals wider than the change itself (±13.3 and ±12.8 percent), so neither is statistically significant.
The inventory figure was significant. New houses for sale at the end of May totalled 496,000, up 2.3 percent from April with an interval of just ±1.2 percent. The resulting months' supply was 10.3, against 9.3 in April and 9.7 a year earlier.
Months' supply is a ratio, not a count
The 10.3-month figure is the standing inventory divided by the current monthly sales pace. It rose in May mainly because the denominator fell, not because builders added a large volume of homes. The inventory count itself was 1.4 percent below the year-earlier level.
That distinction matters for how the number should be read. A supply ratio that climbs on weak sales tends to reverse quickly if sales recover, whereas one that climbs on rising unsold stock takes price or incentive adjustment to clear. May was the first kind.
Prices moved in the opposite direction
The median new-home sale price was $424,900 in May, 2.0 percent above April and effectively unchanged from May 2025's $424,800. The average price was $540,600, up 7.8 percent from April. Neither price change was statistically significant at 90 percent confidence.
New-home median prices are also a mix statistic: they reflect what builders sold that month, not the change in value of a fixed home. A month in which a larger share of closings came from higher-priced product will lift the median without any individual price rising. The gap between the median and the average widening to roughly $116,000 is consistent with that kind of mix effect.
Context for the rest of 2026
By the July report, published August 25, the for-sale count stood at 488,000 with a stage-of-construction split of 115,000 not started, 256,000 under construction and 117,000 completed. Completed, unsold inventory is the portion that carries the most direct pressure to discount, and it remained under a quarter of the total.
Analysis: the May report is best read as an early signal that builders' pricing power had flattened while their standing stock had not yet cleared. Census does not publish incentive or concession data, so the cost of moving that inventory is not visible in this release.
Regional sales and the price distribution
The regional pattern in May was unusually wide. Sales fell 26.9 percent month over month in the West and 17.0 percent year over year; the Northeast rose 3.0 percent for the month and 17.2 percent for the year; the Midwest rose 16.2 percent for the month while falling 3.7 percent for the year; and the South fell 4.1 percent and 5.4 percent respectively.
Those regional figures come with the same caution as the national one: new-home sales are a small monthly sample and regional moves of this size routinely reverse. The inventory increase, by contrast, was one of the few statistically significant changes in the release, at 496,000 homes for sale, up 2.3 percent (±1.2 percent) from April.
On pricing, the median of $424,900 sat alongside an average of $540,600, a gap that reflects a sales mix weighted toward higher-priced homes. Analysis of the same release found roughly 15 percent of new homes sold below $300,000, which is the clearest single indicator of how little of the new-construction market reaches entry-level buyers. In unadjusted terms 51,000 homes sold in May, against 59,000 in April and 56,000 in May 2025.
