21st Century ROAD Act bans Wall Street from buying 350+ homes

The 21st Century ROAD to Housing Act became law July 11 without President Donald Trump's signature, barring firms that own 350 or more single-family homes from purchasing additional ones or facing fines of as much as $1 million.

"The provisions that the senator fought for give cities additional tools to protect neighborhoods, expand opportunities for first-time homebuyers and help responsible local landlords compete on a more level playing field," Atlanta Mayor Andre Dickens said at a July 13 press conference with Sen. Raphael Warnock, the Georgia Democrat who sponsored the bill.

The legislation passed the Senate 85-5 and the House 358-32 before Trump declined to sign it, allowing it to become law after the constitutionally required 10-day period. Revenue from fines will fund new housing construction and first-time homebuyer assistance. The bill also authorizes $1 billion in grants for local governments to incentivize building, creates a $200 million program rewarding cities that eliminate restrictive zoning, and penalizes slow-growth communities by cutting Community Development Block Grant funding by 10%.

The law addresses a national shortage of more than 4 million homes, according to Realtor.com estimates, a consequence of more than a decade of underbuilding. In Atlanta alone, large corporations own more than one in four single-family homes — over 72,000 properties. The question is whether restricting investor demand for existing homes while pushing them toward new construction will lower prices or simply shift competition into the rental market.

The 45-provision, 381-page bill represents the most significant federal housing reform in three decades. Beyond the investor restrictions, it includes measures from Warnock's Appraisal Modernization Act, which lets homeowners request a second appraisal to address bias, and streamlines environmental reviews for low-impact HUD projects to accelerate construction timelines.

New Supply vs. Existing-Home Demand

The dual-pronged approach creates an uncertain outlook. Joel Berner, senior economist at Realtor.com, said it could take years for a meaningful increase in production to materialize. "It could take years for a meaningful uptick in production to materialize and longer for it to have any impact on overall affordability," Berner said.

Jay Shuman, an attorney at Nelson Mullins who focuses on real estate, said developers and homebuyers need clarity on some provisions, particularly the investor ban. "These are not large regulatory changes necessarily, other than the institutional investor rules," Shuman said. "But these things are the type that will stimulate more development, more supply, and make more deals pencil, particularly at the margins."

The legislation also updates Federal Housing Administration lending standards for manufactured and modular homes, giving them financing parity with traditional site-built homes. That could lower construction costs if adopted more widely, according to Realtor.com Chief Economist Danielle Hale.

What Comes Next

Congress still needs to approve funding for several new mandates, Berner noted. The economist said supply growth can close the housing shortage "especially as building is encouraged in the places that need it the most — the places where it's currently hard to build due to regulatory burden."

The law's effectiveness will depend on whether institutional investors redirect capital into new construction as intended or instead compete more aggressively in rental markets, potentially pushing rents higher. Homebuilder stocks could benefit from increased construction incentives, while real estate investment trusts focused on single-family rentals face headwinds from the purchasing restrictions.
