Builders Hold Double the Supply You Do. Price Around That Gap.

There is no single housing supply number right now. There are two, and they point in opposite directions. New homes carry 9.3 months of supply as of June 2026, roughly double the 4.6 months in the existing-home market where you actually sell. Quote the wrong one and you will price your house wrong.

The number that applies to you

Start with your market. Per the National Association of Realtors, existing-home inventory in July 2026 was 1.54 million units, down 1.9 percent from June and down 0.6 percent from July 2025. That is 4.6 months of supply, unchanged from both the prior month and a year earlier, and well short of the six months that defines balance. Prices confirm the tightness: the July 2026 median existing-home price was $434,100, up 2.0 percent year over year, the 37th straight month of annual gains.

Now the other market. Per the Census Bureau and HUD, 485,000 new houses sat for sale at the end of June 2026, a 9.3-month supply at the current sales pace. TD Economics notes builders continue to lean on price concessions and incentives to clear that overhang.

So the honest answer to "is there a glut" is yes for builders, no for you. Any analysis that cites one figure and calls it housing supply is missing the split. Our national housing market report tracks both series for this reason.

The builder across the street sets your ceiling

When you list an existing home, your real competition is not just the resale down the block. It is the builder with nine-plus months of standing inventory and a balance sheet that can buy down the buyer's mortgage rate.

Financing cost makes that weapon potent. Freddie Mac's Primary Mortgage Market Survey put the 30-year fixed at 6.69 percent for the week ending August 6, 2026, the highest weekly reading of the year to that point, with rates trending up into late summer. At those levels, a builder buying a loan down into the high 5s hands the buyer thousands of dollars a resale seller cannot match without cutting price.

The consequence is local. In metros heavy with new construction, concentrated in the Sun Belt, the builder's incentive package is your effective price ceiling, not the last resale comp. In supply-starved existing markets across much of the Northeast and Midwest, that ceiling barely exists. The national 4.6-month figure tells you nothing about which side you are on. Our city-level market reports can tell you how much new-build competition sits near your listing.

Starts fell 12.4 percent, so the glut is draining

The overhang has an expiration date, and it is worth pricing in. July 2026 Census data shows total housing starts fell 12.4 percent from June and 13.5 percent year over year to a 1.239 million annual pace, with single-family starts down 9.9 percent. Completions ran at a 1.212 million pace, 16.8 percent below July 2025.

Fewer starts today means less new supply competing with you in roughly 12 to 18 months. If builder incentives are undercutting your comps now, that pressure should thin as the pipeline empties. In new-construction metros, that reframes the sell-now-or-wait question: waiting may put you into a market with fewer discounted new homes, not more.

Pull one number before you list

Broad resale values are not cracking under the builder overhang. Our own ZIP-level tracking puts the typical US home near $289,803 as of July 2026, up 3.0 percent year over year, consistent with tight existing supply rather than the new-home glut. Before you set a price, do one thing: count the unsold new construction in your ZIP and find out what those builders are offering on rate buydowns. Then set your price against that package, not the national headline. Our pricing and selling guides walk through how to run that comparison.
