The For-Sale Side: A Vacancy Rate Near Rock Bottom
The homeowner vacancy rate measures the share of for-sale homes sitting empty and available. When it is high, buyers have choices and prices soften. When it is low, listings sell fast and bidding tightens. In early 2026 it was 1.1%.[1] For context, the rate historically ran closer to 1.5-2.0%, and rose to roughly 2.6-2.9% during the 2008 downturn, when the market was flooded with unsold homes.[2] Today it is running well below its long-run norm.

Lower means fewer homes available to buy. Historical values are approximate reference points.

The Rental Side: What Building Actually Did
The apartment market tells the opposite story, and it is the more hopeful one. Rental vacancy fell to a pandemic-era low near 5.6% around 2021 and 2022, when renters competed hard for scarce units and rents spiked.[3] Then developers delivered. As a large wave of new multifamily supply came online, vacancy climbed back toward 7%, reaching 7.3% by early 2026, and rent growth cooled as those apartments were completed.[3]

Higher vacancy here is the good outcome: more supply, more slack, cooler rents.

The Lesson From the Rental Market
The apartment sector ran the experiment for us. When supply expanded, the squeeze eased. Vacancy rose, renters gained leverage, and rent growth slowed. The same mechanism would work for buyers - if starter homes were built at the same pace.
Where We Built vs. Where We Did Not
In 2024, home completions reached about 1.6 million units, the highest total in nearly two decades.[4] That is real construction. But it was disproportionately multifamily rental. For-sale starter inventory stayed scarce, and the homeowner vacancy rate shows it.[4] The two markets received very different amounts of new supply, and they produced very different outcomes.
| Segment | New Supply | Vacancy Signal | Result |
|---|---|---|---|
| Multifamily rental | New supply delivered | Vacancy ~5.6% to 7.3% | Rent growth cooled |
| For-sale starter homes | Underbuilt | Vacancy 1.1%, near record low | Scarcity persists |

This raises a straightforward question. If added supply visibly relieved pressure in the rental market, why not direct the same effort at the homes families are trying to buy? The for-sale drought is not a mystery of demand alone. It is a shortfall of the right kind of building.
Policy Connection
The rental market shows that supply eases prices. The for-sale market shows what happens when that supply does not arrive. The Affordability and Immigration Act addresses both sides of that equation:
- -Policy 5 increases housing construction through federal-local partnerships that reward jurisdictions producing homes, including the entry-level for-sale housing that is in shortest supply.
- -Policy 2 aligns population growth with housing capacity, so a decade of building can close the gap rather than run permanently behind demand.
