How Washington’s war on ‘Wall Street landlords’ could backfire on Gen Z renters

The 21st Century ROAD to Housing Act, which combined House and Senate housing packages and passed with rare bipartisan support from lawmakers including Sen. Elizabeth Warren, Sen. Tim Scott, Rep. Maxine Waters and Rep. French Hill, restricts how many single-family homes large institutional investors can own and imposes new reporting requirements. The bill followed a wave of more than 76 state-level bills in 2026 targeting corporate landlords, reflecting bipartisan appetite for action on an issue voters rank among their top financial anxieties.

The political rhetoric behind the crackdown has been unusually blunt for a bipartisan bill. “These Wall Street types are swooping in to buy up a bunch of single-family homes that should be going to you, to families,” Sen. Elizabeth Warren said in describing the law’s intent. “Let’s be honest, most Americans just can’t outbid a Wall Street billionaire private equity firm. Once private equity owns these homes, they become bad landlords. They raise the rents, charging exorbitant fees, leaving maintenance requests unanswered, and filing unfair evictions.”

President Trump used nearly identical framing when he first proposed barring institutional investors from the housing market outright, declaring that “people live in homes, not corporations” — a rare instance of the president and one of his most consistent Senate critics agreeing almost word for word on the diagnosis, if not the mechanics, of the housing crisis.

But institutional operators — defined as entities owning more than 350 single-family homes — own just 0.7% of the 92 million single-family homes in America, roughly 5% of all 14 million rental homes in America, and 1% of the 4.7 million homes purchased in America in 2025, according to an analysis by John Burns Research and Consulting. “We might as well call this the ‘Rental Inflation Bill,’” the Burns team wrote in March, updating their assessment through July. “We are not policy experts, but we do understand how demand, supply, and new development underwriting work in the housing market.”

The Burns team concluded that the bill will decrease new construction, increase rents, and increase home prices, even though it’s surely not what the bill’s authors intended. One provision, requiring rental home developers to sell the homes to homeowners within seven years, will simply result in a construction dip, and the resulting reduction in supply will lead to higher rents, which will have a knock-on effect on higher home prices.

Institutional investors and an overlooked dynamic

Lance Lambert, a housing market researcher and founder of ResiClub Analytics, offered independent confirmation of the mechanism at the center of this debate. “Institutional capital has been a key driver of Build-to-Rent deployment in America’s fastest-growing markets, helping add rental supply to keep pace with population gains,” he told Fortune.

Lambert pointed to an overlooked dynamic in how that capital actually accelerates new construction: institutional buyers give homebuilders a release valve for excess inventory, letting them “turn capital faster” — knowing that if they’re in a pinch with lingering spec inventory, they can sell some to investors and move on to the next community sooner. That framing complicates the idea that institutional buyers simply hoover up existing homes; in the build-to-rent context, they’re often what makes new supply pencil out in the first place.

Lambert also confirmed the chilling effect described by industry insiders extends beyond the letter of the law. “While the recent federal bill carved out an exemption for Build-to-Rent, political pressure remains at the state level, which has left some institutional players still hesitant to deploy further into housing,” he said. In other words, even a federal exemption hasn’t fully restored investor confidence — the reputational and regulatory uncertainty is doing damage the statute’s text doesn’t capture.

Independent economists have put more blame on the national debt than on institutional landlords. Yale’s Budget Lab estimates federal debt growth has pushed long-term Treasury yields up roughly 97 basis points, adding about $2,500 a year — or $76,000 over a 30-year loan — to the median mortgage. Texas A&M’s Real Estate Research Center calculated a nearly identical figure independently. The Bipartisan Policy Center concluded that “the national debt hasn’t caused today’s housing problems, but if it continues to grow, it will make solving them more difficult.”

(How much) is Gen Z actually screwed?

Gen Z has entered adulthood already absorbing a heavier rent burden than prior generations, with 2026 data revealing a more nuanced — and more urgent — story than a simple affordability crisis: multifamily apartment rents have actually been easing, while single-family rental prices, the exact asset class targeted by the new law, are already accelerating.

Broad apartment-market data has been genuinely favorable to renters in recent months. Median asking rent across the 50 largest U.S. metros fell 1% year-over-year as of November 2025 — the 28th consecutive month of year-over-year decline. That relief carried into 2026: rents were down 1.7% year-over-year by February 2026, with a growing share of the 50 largest metros shifting into renter-friendly or balanced territory as new multifamily supply came online. By June 2026, the median asking rent across the 50 largest metros stood at $1,692, down 1.5% year-over-year, with more than 300,000 new multifamily units delivered in 2025 alone continuing to keep pressure on landlords. Still, that was $238, or 16.4%, higher than the pre-pandemic level.

But single-family rentals — the product institutional investors like Amherst specialize in, and the one directly targeted by the ROAD to Housing Act — are moving in the opposite direction. By March 2026, single-family rents were rising in 49 of the 50 largest U.S. metro areas. That divergence is the crux of the story: the segment of the rental market that was cooling — multifamily apartments — isn’t the one at risk from this legislation, while the segment already heating up — single-family homes — is precisely the one whose supply pipeline the bill threatens to constrain further.

That divide supports Lambert’s more measured read on the underlying cycle. “Weakness in the Sun Belt’s rental market won’t last forever,” he said, describing the softness as “that post-boom correction” that “has been playing out since mid-2022.” He notes that while pockets of weakness remain across Texas, Florida and Colorado, “we’re slowly nearing an inflection point,” with new construction volumes having “rolled over from the highs” and underlying fundamentals moving back into balance — a trajectory now visible in the single-family rent data itself, which suggests the correction Lambert describes may already be ending just as the legislative crackdown on institutional capital takes effect.
