Why Banning Big Landlords Won’t Fix the US Housing Crisis

Property rights, investment and the risk to future supply

A core cost of the proposed ban is its effect on property rights and investor behavior. Restricting what investors can buy alters the expected return and increases political risk. Historical evidence from other interventions — most prominently severe rent control — shows that when returns and rights are curtailed, capital exits and maintenance and new investment decline.

Two points are important here:

• Private capital did play a role after the 2008 crisis by buying foreclosed single-family homes and stabilizing communities. If investors become wary because of retroactive or sweeping restrictions, that source of capital could shrink.
• The institutional SFR sector is small now, but if restrictions reduce reinvestment in SFR and multifamily, the cumulative effect could be a longer-term contraction in rental supply, worsening affordability rather than improving it.

Regulatory uncertainty also multiplies enforcement costs. Policymakers would need to define "institutional" precisely, monitor transactions, and process carve-outs. Those administrative burdens are not free, and setup costs will be passed into the market in one form or another.

Who wins and who loses under a ban

Policy debates often frame markets in terms of winners and losers. Here is how this proposal would break down across stakeholders:

• Renters in affected markets: Lose on average, because institutional landlords have tended to lower rents modestly through scale and efficiencies. Banning future purchases reduces rental supply and can push rents up.
• Prospective homebuyers in targeted neighborhoods: Some will benefit if a small additional number of homes are available for purchase, but the total gain is small relative to demand.
• Small mom-and-pop landlords: Mixed outcomes. Competition from large firms sometimes pushed out smaller landlords, but Coven (2025) finds relatively few smaller SFR landlords were wiped out by institutional entry. A ban could protect some smaller owners but also reduce service and financing options.
• Institutional investors and capital providers: Lose or reduce appetite to invest in the sector, potentially reducing future rehabilitation and upkeep of properties that serve rental households.
• Policymakers and municipalities: Face enforcement costs and the risk of unintended market consequences.

What really drives housing affordability — and what policy should target

If the policy goal is improved affordability for either buyers or renters, the research points to a much different target than institutional SFR ownership: the shortage of new housing supply. Over the past decade and longer, the United States has underproduced new homes in relation to population growth and household formation. This supply gap is the major structural driver of both rising home prices and rents.

Policies that would have a larger, more measurable impact include:

• Deregulating or streamlining land-use and zoning rules that prevent the construction of more housing near job centers.
• Incentivizing construction of both rental and owner-occupied housing, including denser housing types and accessory dwelling units where appropriate.
• Direct subsidies or support for low-income renters and first-time buyers where needed, targeted to households rather than asset classes.
• Stronger antitrust enforcement in markets with concentrated landlord ownership to address monopoly pricing where it exists.

A national ban on institutional SFR purchases rearranges the existing housing stock but does not materially increase the flow of new homes. For the scale of the affordability problem, that is why the proposal is unlikely to be an effective lever.

Practical guidance for buyers, investors and renters

Here is how different market participants should think about the proposal and its likely consequences:

• Homebuyers and prospective owner-occupiers:

  • Monitor local SFR concentration. If your target neighborhood shows heavy institutional ownership, a ban could modestly increase availability, but expect competition to remain intense.
  • Focus on supply-side changes in your metro — is your city permitting enough housing? That matters more for prices than a narrow ban.

• Renters:

  • If you live in a market with high institutional presence, the research suggests rents may be lower than in comparable localities without institutional competition. A ban could remove that downward pressure.
  • Watch for local policy moves that could affect rent protections or tenant services as the politics around housing evolve.

• Individual landlords and small investors:

  • Consider that restrictions on institutional buyers may lead to increased investor attention on smaller rental portfolios, potentially raising competition for acquisitions.
  • Factor regulatory risk into your investment horizon, but also evaluate efficiency gains that larger operators bring.

• Institutional investors and REITs:

  • Anticipate higher political scrutiny and prepare governance controls, reporting transparency, and community engagement strategies to reduce reputational and regulatory risk.

• Policy watchers and municipal leaders:

  • If the goal is affordability, prioritize removing barriers to new construction and addressing concentrated market power through targeted enforcement rather than broad purchase bans.

Conclusion: reshuffling stock is not a substitute for building more houses

The president’s proposal to ban institutional purchases of single-family homes is politically resonant, but the evidence indicates it will not meaningfully relieve national housing affordability pressures. The institutional SFR share of the rental market is small — about 3% of the rental stock and under 2% of the owner-occupied stock — and the net supply effects of institutional buying are modest at best (~0.22 homes returned to buyers per institutional purchase). For renters, the policy could do harm because larger landlords have in many cases reduced rents through scale and efficiency.

If policymakers genuinely want to improve housing affordability, the focus should be on increasing the flow of new housing where people need it and addressing local market power with precise tools. We can debate the merits of restricting certain forms of ownership, but lawmakers should weigh the trade-offs in evidence rather than rely on symbolic measures that reshuffle rather than grow housing supply.

Frequently Asked Questions

Q: How much of the US housing stock is owned by institutional investors?
A: Recent research (Ellen & Goodman, 2023) estimates institutional owners hold just over 3% of the rental stock, which is under 2% of the owner-occupied stock nationally.

Q: Would banning institutional buyers make it easier for first-time buyers to find homes?
A: A ban would slightly increase the supply of houses available to purchase but by a small amount — research suggests about 0.22 extra homes for buyers per institutional purchase — too small to change affordability broadly.

Q: Could the ban lead to higher rents?
A: Yes. Studies show that institutional entry often lowered rents modestly through scale and efficiency; preventing that entry can reduce rental supply and put upward pressure on rents for existing and future renters.

Q: What policy actions would have more impact on housing affordability?
A: Targeted actions that expand housing supply — reforms to zoning and permitting, incentives for new construction, and antitrust enforcement in markets with concentrated ownership — have more direct effects on prices and rents than a national ban on institutional purchases.
