Where Could Trump’s Institutional Investor Ban Help the Most?

President Donald Trump is taking another swing at improving housing affordability, this time, by targeting institutional investors.

“I am immediately taking steps to ban large institutional investors from buying more single-family homes, and I will be calling on Congress to codify it,” he wrote in a Truth Social post. “People live in homes, not corporations.”

Details have yet to emerge about the specifics of what such legislation would look like, and the White House did not immediately return a request for comment from Realtor.com®. But the political appeal is obvious: Blame Wall Street, free up homes for families. 

Except investor buying isn’t evenly spread across the country. In much of the U.S., a ban would land softly where affordability is already strained. And in the few places where it could move the needle, it could also scramble the local rental pipeline in ways that create a different kind of squeeze.

Big institutional investors have a small national presence

To understand what Trump’s proposed ban could accomplish, it’s important to first clarify who and what it targets at this earliest stage. The primary focus for now is on institutional investors—typically defined as entities that own 100 or more homes. The second target is the type of housing they own: Single-family homes held as rental properties.

While mega-investors loom large in the political imagination, their actual footprint in the U.S. housing market is relatively limited.

“Institutional investor impact on the overall housing market (both the rented and owned space) is highly exaggerated by politicians on both sides of the aisle,” says Jake Krimmel, senior economist at Realtor.com.

As of November 2025, institutional investors owned only about 1% of America’s single-family rental stock, according to an analysis of Parcl Labs data by the American Enterprise Institute. Other estimates put that figure slightly higher at around 2% to 3%.

So why are they such a common political punching bag?

“Wall Street investors sound sinister but they're a red herring when it comes to the housing affordability crisis,” Krimmel explains. “Nationally and in the vast, vast majority of neighborhoods, they simply are not big players, so preventing them from buying single-family homes going forward won't actually free up that much inventory for traditional buyers.”

Alex Blackwood, CEO of real estate platform Mogul, puts it more bluntly: “Honestly, I think it's more of a scapegoat than anything else.”

Still, the politics are potent. In a recent Realtor.com survey, a majority of Americans said they view homeownership as part of the American dream, yet far fewer believe that dream is within reach.

That can make any investor activity, no matter what size, feel like a slap in the face. And while investors have played a role in the housing market, their influence is overwhelmingly driven by small, mom-and-pop buyers.

In mid-2025, investors accounted for 10.8% of home purchases, and more than 60% of that activity came from small investors (defined as those with 10 or fewer purchases since 2001), according to the most recent Investor Report from Realtor.com.

Even with generously defining “large investor” as those with 51 or more lifetime purchases, they still made up less than 20% of investor purchases in the first half of 2025. And their share has been steadily shrinking since 2022, while smaller investors have grown more active, reaching their highest share since 2007.

“In other words,” Krimmel says, “the segment this policy targets is an already narrow and shrinking slice of the market.”

Yet the tension remains. While everyday Americans feel locked out of homeownership, investors large and small continue to hold ground, making the idea of a ban like this resonate.

But Krimmel cautions that even if such a ban were legally feasible, it wouldn’t solve the root problem.

“The proposed ban might resonate politically, but the numbers suggest it would have limited reach and would not address the core shortage driving today’s housing affordability issues,” he says.

In select metros, they own as much as 27% of single-family home stock

While large institutional investors make up a small share of the housing market nationally, their presence in certain metro areas is far more concentrated—and that’s where a federal ban could make a difference.

A now widely cited 2023 report from the Hamilton Project found that nearly 80% of the 446,000 single-family homes owned by mega-investors (those who own 1,000 or more homes) were located in just 20 metro areas, mostly in the Southeast and Southwest.

“On a hyper-local scale, a ban on future institutional investment could have some small bite. But these are the exception, not the rule,” says Krimmel.

In Atlanta, institutional investors own 27% of all single-family rental homes, the report found. In Jacksonville, the share is 22%. In Charlotte, it’s nearly 20%. In these places, a freeze on future acquisitions could plausibly slow investor growth and modestly expand homebuying opportunities over time.

In areas with high concentrations of institutional investment, about 70% of the homes they acquired were previously owned by individual homeowners, according to one study from Konhee Chang at the University of California Berkeley. Once converted to rentals, those homes rarely return to the market for buyers.

Blackwood says a driver of this is logistical difficulty. 

“It’s really hard to turn that into a not-for-rent. You already have renters in place,” he explains. “Someone’s not going to basically say, ‘We’re going to make sure all the houses are empty for the next buyer.’ That would be very tough to do.”

That creates a local supply shock for homebuyers that can drive down homeownership rates and push up home prices. Chang’s research found that in census tracts where investors acquired 10 or more properties, homeownership rates fell by about 2%, while home prices rose by a similar amount.

Krimmel emphasizes that while these investor-dominated neighborhoods exist, they’re not the norm, and focusing on them can obscure the deeper root cause of housing affordability.

“These are edge cases, though” he says. "The affordability crisis is fundamentally a supply problem, and meaningful relief requires adding homes, both through new construction or through inventory gains in chronically constrained markets."

Investor hot spots aren’t where affordability is most acute right now

Even in the limited number of markets where institutional investors have a strong presence, affordability pressures have eased in recent months, making the logic of a national ban even more disconnected from the housing market’s current pain points.

“Institutional investor activity is most prominent in the Sun Belt, which ironically has seen the least affordability pressures recently,” says Krimmel. “Compared to other regions, home prices have fallen the most in the South and inventory has increased the greatest.”

Meanwhile, the worst affordability conditions are showing up in places with very little institutional investor activity.

“The affordability crisis is most acute in the Northeast, Midwest, and large West Coast cities right now—all areas where institutional investors have little to no footprint,” Krimmel explains. “So banning them from future purchases would have no bite in the most supply- and inventory-constrained parts of the nation.”

He also warns that the ban could end up hurting renters. These investors have expanded the housing stock expanding rental options, particularly in suburban areas where multifamily housing is scarce.

This increase in rental supply has measurable effects. In census tracts with significant investor activity, Chang’s research finds that while home prices rose by an average of 2.2%, rents actually declined by about 2%.

These dynamics are particularly important for middle- and lower-income renters, who may benefit from access to single-family homes in school districts and neighborhoods they couldn’t otherwise afford.

So who could it help?

According to Blackwell, the biggest beneficiaries may not be traditional buyers, but rather the very small-scale investors who already dominate investor activity nationwide.

If the proposed ban targets only large firms, it’s unlikely to flood the market with homes for individual buyers. Instead, it may simply shift market share, from institutional giants to smaller players.

And that shift may already be underway. Over a recent 21-month period, large institutional investors sold more homes than they bought, acquiring 178,000 and selling 185,000, for a net decline of 7,000 homes in their portfolios, according to the American Enterprise Institute. Keep in mind, that’s up against small investors commanding their largest share of home purchases since 2007.

In other words, a policy aimed at Wall Street may end up empowering Main Street—just not in the way many might expect.
