The largest landlords in the United States are buying houses again, though on a small scale. Inman reported on Monday 5 October 2026 that so-called mega investors, meaning owners of 1,000 homes or more, bought 2.2% of the single-family homes sold in August. The figure comes from the September market analysis of the data firm Cotality, as relayed by the economists of a national property portal and then by Inman.

That share is 0.8 percentage points above the low of 1.4% that the same series touched in February 2026. The rise follows a new federal law, in force since July, that bars the biggest owners from most further purchases of single-family homes. The portal's economists say it is too early to tell whether institutional buying is really growing: the measure to watch, in their view, is the number of transactions.

Purchase shares: Cotality's September analysis, as reported by Inman on 5 October 2026. Cap: HousingWire, 14 July 2026.

What the figure counts

The number is a share of purchases in one month, for one size of buyer. Cotality's category of mega investor starts at 1,000 homes owned, and Inman's report gives no figure for smaller investors, so the 2.2% says nothing about the landlord with five houses or the local company with fifty. It also says nothing, on its own, about how many homes changed hands. A share can rise because one group buys more, or because everyone else buys less.

That second reading is taken seriously by the people who published the analysis. Hannah Jones, a senior economist at the portal, told Inman that institutional buyers depend less on mortgages and pay cash more often than households do. When borrowing costs push individual buyers out, the cash buyers who remain take a larger slice of a smaller market without doing anything new. Inman's report describes individual buyers as held back by mortgage rates above 7%, by inflation and by other market headwinds.

Jones also offered a second explanation: institutional activity may have slowed while federal policy was unclear and still changing. Inman adds that the passage of the law reduced that uncertainty and let investors adjust their strategies to its provisions. Her test for the months ahead is transaction volume, which will show whether institutional buying is growing or whether the rest of the market is shrinking around it.

The law behind the pause

The policy in question is the 21st Century ROAD to Housing Act. HousingWire reported on 14 July 2026 that the bipartisan package took effect on 11 July without the president's signature, after he neither signed nor vetoed it within the ten-day window. It followed an executive order issued in January that directed federal agencies to limit the role of large institutional investors in single-family housing and called for legislation to put the policy into statute.

According to HousingWire, the Act bars institutional investors that own or control at least 350 single-family homes from buying more of them. The prohibition covers purchases, transfers, mergers and bulk acquisitions. It does not reach backwards: companies are not required to sell homes they owned before the law took effect.

The threshold matters for reading the Cotality figure. A mega investor in the data owns 1,000 homes or more, well above the 350-home line, so every buyer in the 2.2% is one the Act covers. Their August purchases therefore sit inside the exceptions the law leaves open, or reflect arrangements the reports do not describe. HousingWire lists those exceptions as follows:

1. Newly built homes acquired through build-to-rent developments.
2. Substantially rehabilitated homes acquired through renovate-to-rent programmes.
3. Homes bought as part of qualifying lease-to-own and homeownership initiatives.
4. Properties acquired through foreclosure or other loss-mitigation activity.
5. Certain age-restricted housing communities.
6. Transactions in homes already owned by other institutional investors, under specified conditions.

Neither Inman nor HousingWire breaks the August purchases down by exception, so the reports do not say which of these routes carried the rebound.

Two views of the same buyers

The provision was proposed by Senator Raphael Warnock of Georgia. HousingWire reports his argument that large private equity firms make it harder for first-time and other would-be buyers to compete, by buying homes in bulk and treating housing as an investment asset. His office says corporate investors own more than 72,000 single-family rental homes in the Atlanta metropolitan area, more than one in four such properties in the region.

The concern is local before it is national. The Inman opinion column of 22 July cited the Government Accountability Office for the share of single-family rentals in institutional hands in four Sun Belt cities: 25% in Atlanta, 21% in Jacksonville, 18% in Charlotte and 15% in Tampa. Those are shares of rented houses, not of all houses, but they are far above the national estimate of about 3% quoted in the same column.

The rental industry reads the same facts differently. In an article dated 12 March 2026, the National Multifamily Housing Council argued that the provision, then a late addition to the bill, was poorly targeted because it placed build-to-rent housing in the same category as scattered single-family rentals. Build-to-rent communities, it said, are purpose-built and professionally managed, and restricting them would be more likely to stop homes being built than to produce homes for sale. The council also pointed out how quickly an operator reaches the 350-home line: a firm with seven communities of 50 or more homes is already there.

The version that became law answers part of that objection. As HousingWire describes it, covered investors may still acquire newly constructed homes through build-to-rent developments, and Inman reports that federal lawmakers removed restrictions on such communities. An owner-occupier competing for an existing house and a landlord building new rental houses are, under the Act, treated as two different cases.

Build-to-rent, the open door

That distinction is why Inman expects the next wave of institutional buying, if there is one, to be directed at communities of houses built to be let. Inman adds that the typical American does not move from renting to owning until about the age of 40, which lengthens the years a household spends as a tenant.

The scale of the sector is measured in several ways. The National Multifamily Housing Council's March paper cited Pew's estimate that roughly 70,000 to 130,000 build-to-rent homes were built annually over the last several years, and Yardi Matrix's count of 47,000 units completed in 2025 in communities of 50 units or more.

Development has slowed since its peak, and here two reports describe the same number differently. Inman reports that build-to-rent starts peaked at 122,000 in early 2024 and, crediting the National Association of Home Builders, that they fell 16% from a year earlier to 15,000 in August. The National Apartment Association's analysis of the sector through the first quarter of 2026, which Inman links to, gives the figure of more than 122,000 in early 2024 as units under construction, falling to about 63,000 by the first quarter of 2026. Both describe a sharp pullback; they do not agree on what the 122,000 measures.

The association's figures show two movements at once. Units under construction have fallen by nearly half, while completions from the earlier expansion kept arriving and peaked at more than 12,300 units in the second quarter of 2025. Rents have stopped rising, and the association reports that operators are making growing use of concessions. It describes demand as stable, and occupancy as having steadied since mid-2025. Inman quotes the association as saying that build-to-rent now works as a core component of housing supply, not as an alternative option.

For tenants, that is a softer market than the one of 2023. Apartment List's national report of 29 September 2026 put the rental vacancy rate at 7.0% and rents 0.4% lower than a year earlier, across rental housing as a whole.

Where the money is going

The retreat is uneven across the map. The National Apartment Association found the steepest year-on-year falls in active development pipelines in large Sun Belt markets: 58% in Austin, 46% in Phoenix, 38% in Charlotte and 20% in Orlando. Completions in the first quarter of 2026 were still led by Phoenix, with 872 units, followed by north Dallas with 583 and Boise with 473.

Investment sales tell the same story from the buyer's side. Quarterly sales of build-to-rent communities peaked at more than US$1 billion in the third quarter of 2023, dipped to US$228 million in the first quarter of 2025, recovered to US$758 million in the fourth quarter of 2025 and stayed above US$500 million in early 2026, according to the association. Of the five metropolitan areas it names as receiving capital in the first quarter of 2026, only Charlotte is among the Sun Belt markets where pipelines fell most.

Charlotte appears on both lists: its development pipeline shrank by 38% while the association counted US$41.3 million of sales there. Less is being started in that market, yet built communities still find buyers.

Developers in the sector describe steady demand. "The long-term demand and need never went anywhere," Kelli Lawrence, chief executive of the Indianapolis build-to-rent developer Onyx+East, told Inman.

What owner-occupiers and agents can take from it

For a household buying an existing home, the practical point is the cap itself. Under the Act as HousingWire reports it, an owner of 350 or more single-family homes can no longer buy a resale house unless one of the listed exceptions applies. Investors below that line are not covered by the cap, and the August figure does not measure them.

For a household that rents, the direction of the law is towards more purpose-built rental houses, not fewer, since newly built rental homes are among the routes left open to the largest owners. Whether they are built depends on the economics the National Apartment Association describes: flat rents, occupancy near 92% and a construction pipeline roughly half its peak.

For listing agents and brokers, the August figure is small but not nothing. About one single-family purchase in 45 went to an owner of 1,000 homes or more, and each of those sales had to fit an exception in the law. Sellers of newly built or substantially rehabilitated homes, and lenders disposing of foreclosed property, are the ones most likely to meet such a buyer.

What to watch next

Three things remain open in the published material. The first is volume: Jones named it as the measure that will separate a real increase in institutional buying from a market shrinking around cash buyers, and the reports give the August share without the number of homes behind it. The second is the route: neither Cotality's share nor the press reports say how much of the buying was new build-to-rent stock and how much used the other exceptions. The third is supply, where the starts and construction figures point down even as the law points investors towards building.

Until later months of the series are published, the August number supports a modest reading. The largest owners have not left the single-family market, they are buying a little more than they did in February, and the rules now steer them towards houses that did not exist before.
