What is new home sales

New home sales, which the Census Bureau calls New Residential Sales, count contracts signed on newly built single-family houses. The Census Bureau and the Department of Housing and Urban Development (HUD) publish the series jointly each month. A sale registers when a buyer signs or puts down a deposit, so the house can be unbuilt, under construction or finished.

Custom homes on an owner's land, rentals and multifamily units are left out. New homes make up roughly 10% to 15% of all US home transactions.

The headline is a seasonally adjusted annual rate (SAAR), which takes one month's pace and scales it to a full year. The August 2026 release showed 684,000, up 6.4% from July's revised 643,000 but −2.0% from a year earlier.

Why it matters

It works like a purchase order. Existing-home sales are booked at closing, after 30 to 60 days of underwriting. New home sales are booked at commitment, which is why they tend to lead existing-home data by one to two months.

The series also feeds residential investment in GDP, and builders use it to decide whether to speed up or slow down. Months' supply is inventory divided by the current sales pace, and about 6 months is the conventional balanced market. August showed 483,000 homes for sale, or 8.5 months.

How to interpret it

Start with the error bar. The Survey of Construction samples building-permit offices and scales the results up, so the estimate is noisy. August's 6.4% gain came with a ±19.5% range, which puts plausible outcomes anywhere from roughly −13% to +26%. The Census Bureau cannot rule out that sales fell. Revisions are routine, and July's 643,000 may move again.

The headline also hides things. The median price was $393,700, −5.8% from a year earlier, while volume was flat to slightly lower. Falling prices on steady volume usually mean builders are paying for sales with discounts, smaller homes and mortgage-rate buydowns. Builders are buying demand.

Months' supply improved mostly because sales rose, not because inventory shrank. Revise the sales figure down and the supply reading gets worse with it.

Months' supply has hovered near 8–10 for most of the past two years, well above the 5–6 month range typically treated as balanced, even as the SAAR has swung from the mid-500ks to the high 600ks. Source

Three checks help:

  • Smooth it. Use a three-month average or the year-over-year change rather than a single print.
  • Split volume from price. Ask whether sales rose while the median fell.
  • Cross-check against housing starts and permits. When starts run ahead of sales, months' supply climbs.

Key takeaways

  • New home sales count contracts, so they lead closings-based data.
  • A single monthly change is a point estimate sitting inside a wide range.
  • Price and months' supply often say more than the headline.
  • The August test: if September sales fall back below about 650,000 while the median price stays negative year over year, the bounce was noise. Existing-home sales from the National Association of Realtors give a second read on the contract data.
