Is the US Housing Shortage Over? What Rising Inventory Really Means
If you’ve been watching US housing headlines, you’ve probably seen two seemingly contradictory stories at once: inventory is rising sharply, and yet the country still faces a housing shortage. Both are true — and understanding why is important if you’re weighing a US property investment based on the assumption of long-term rental demand.
Two Different Numbers, Not a Contradiction
Inventory measures how many homes are currently listed for sale at a given moment — a snapshot of what’s available right now. The housing shortage measures a longer-term structural gap: how many additional homes the country would need to build to match household formation and demand over time. One is a monthly or quarterly figure that moves with listings and sales. The other is a slow-moving deficit that’s built up over more than a decade.
These two numbers can move in opposite directions at the same time, and right now, that’s exactly what’s happening. Inventory has been rising because more homeowners are finally listing properties they’d been holding onto during the “lock-in effect” years — a period when giving up a low mortgage rate to move made financial sense to avoid, keeping millions of existing homes off the market. As more of those owners accept the current rate environment and move for other life reasons, existing homes are coming back onto the market in greater numbers.
That’s a real and meaningful shift. But it’s an unlocking of existing supply, not the creation of new supply. It doesn’t, on its own, close the longer-term gap between how many homes exist nationally and how many are actually needed to house the population comfortably.
How Big Is the Shortage, Really?
Here’s where it gets genuinely complicated: estimates of the US housing shortage vary enormously depending on methodology. The National Association of Home Builders puts the figure at roughly 1.2 million units. Goldman Sachs estimates 3–4 million. Zillow has put the number as high as 4.7 million. Brookings estimates around 5 million. McKinsey’s analysis runs to 8 million or more. Some estimates from other researchers and advocacy groups go even higher still.
Why such a wide range for what sounds like it should be a straightforward number to calculate? A few reasons:
- Target vacancy rates differ. Researchers disagree on what a “healthy” vacancy rate looks like, and small differences in that assumption produce large differences in the final shortage estimate.
- Household formation projections vary. Estimating how many new households will form in future years — driven by demographics, immigration, and social trends — involves genuine uncertainty, and different models produce different forecasts.
- Definitions of “available” housing differ. Some estimates count only homes actively for sale or rent; others factor in vacant units, second homes, and homes held off-market for various reasons.
- Some analyses question the framing entirely. A minority of researchers argue the “shortage” framing itself is oversimplified, pointing instead to affordability mismatches — plenty of homes exist, they argue, just not at price points many buyers can afford.
What’s striking is that despite this wide range, nearly every reputable estimate — regardless of methodology — points in the same direction: the US has been underbuilding relative to underlying demand for well over a decade, and that structural gap has not been closed by the recent rise in existing-home inventory. Existing homes coming onto the market and new homes actually being constructed are two entirely different supply sources, and the shortage figure is fundamentally about the latter.
Why New Construction Hasn’t Kept Pace
A few structural factors explain why the shortage persists even as existing-home inventory rises:
- Land use and zoning restrictions. In many metro areas — particularly coastal and high-demand markets — local zoning rules limit density and slow approvals, constraining how much new housing can be built regardless of demand. Economists at Goldman Sachs and elsewhere have pointed to these regulations as the single biggest structural constraint on US housing supply.
- Construction costs have risen. Materials, skilled labor, and financing costs have all increased, making some new development projects less financially viable than they’d otherwise be, particularly for the kind of “missing middle” housing (smaller multifamily, townhomes) that tends to ease shortages most efficiently.
- Apartment construction has slowed sharply from its 2021–2022 peak, which limits new rental supply even as demand for rentals continues — a dynamic several analysts expect to keep upward pressure on rents even as for-sale inventory improves.
- The shortage isn’t evenly distributed geographically. It remains most acute in the Northeast and in coastal markets with the tightest zoning constraints, while parts of the Sun Belt and Midwest have built more aggressively over the past several years and face comparatively less severe local shortages.
What This Means If You’re Investing in US Property
For an investor, the practical implication is this: rising inventory in 2026 has made it meaningfully easier to find and negotiate on a property, without necessarily undermining the longer-term rental demand case in markets that remain genuinely undersupplied.
That said, this isn’t uniform across the country — it depends heavily on the specific metro, and even the specific submarket within it. A property in a metro area actively building at scale faces a different supply-and-demand balance than one in a persistently undersupplied coastal market with restrictive zoning. National headline figures — whether about inventory or about the shortage — are a useful starting point, but due diligence on local supply trends, permitting activity, and rental demand matters considerably more than any single national number when evaluating a specific deal.
For foreign investors financing through DSCR loans — which qualify a property based on projected or in-place rental income rather than the borrower’s personal credit history — this local distinction matters directly, since the loan’s underlying viability depends on the property renting reliably in its specific local market, not on national housing statistics. See our DSCR loans guide for UK & European investors for the detail on how that qualification process works.
FAQ
Is the US housing shortage over in 2026? No. While existing-home inventory has risen as more homeowners list properties, the longer-term structural shortage — driven by years of underbuilding relative to demand — has not been resolved. Estimates of its exact size vary widely, but most researchers agree the underlying gap persists.
Why is housing inventory rising if there’s still a shortage? Rising inventory largely reflects existing homeowners finally selling properties they’d been holding onto during a period of higher mortgage rates, not a surge in new construction. The shortage is primarily about a lack of new homes being built relative to demand — a separate and slower-moving issue than short-term listing activity.
How big is the US housing shortage? Estimates range from roughly 1.2 million units (NAHB) to 8 million or more (McKinsey), with widely cited figures from Goldman Sachs, Zillow, and Brookings falling in between. There is no single agreed-upon number, though nearly all analyses point to a meaningful, persistent gap.
Does the housing shortage affect all US markets equally? No. The shortage is more acute in the Northeast and in coastal markets with restrictive zoning, while some Sun Belt and Midwest metros have built more new housing over recent years and face comparatively less severe local shortages.
