Fact-Checking the Senate's Housing Bill: Do Corporate Landlord Bans Actually Lower Prices?

The US Senate just passed the most sweeping federal housing legislation in two decades. The 21st Century Road to Housing Act cleared the chamber in a rare 85-5 bipartisan landslide, uniting progressive Senator Elizabeth Warren, conservative Senator Tim Scott, and President Donald Trump.[1]

The bill's flagship provision targets a widely despised villain in the modern real estate market: the corporate landlord. If signed into law, the legislation will ban institutional investors who already own more than 350 single-family homes from purchasing any additional properties.[1][3]

The political narrative driving the ban is straightforward and intuitively appealing. Lawmakers argue that Wall Street behemoths are buying up starter homes with all-cash offers, artificially driving up prices, and locking an entire generation of working-class Americans out of the American Dream.[3]

But as the bill heads to the House of Representatives, housing economists and urban policy researchers are urging the public to look at the empirical data. A growing body of evidence suggests that while banning corporate landlords is highly popular, it fundamentally misdiagnoses the root cause of the housing crisis and carries unintended consequences for renters.

The first major misconception involves market share. While it is true that institutional investment in single-family homes surged after the 2008 foreclosure crisis, these mega-landlords own a surprisingly tiny fraction of the market.

According to data from the Urban Institute, large institutional investors own less than 3% of all single-family rental homes in the United States. When looking at the total national housing stock, their footprint shrinks to less than 0.5%.

The vast majority of single-family rentals are actually owned by "mom-and-pop" investors—individuals or small LLCs that own between one and nine properties. Banning the largest corporate players would return, at most, 1% to 2% of the housing stock to the owner-occupied market, a shift too small to meaningfully move the needle on national affordability.

To understand what actually happens when a government bans corporate buyers, researchers point to a massive real-world experiment in the Netherlands. In 2022, the Dutch government passed a law allowing municipalities to ban investors from buying homes to rent them out.

A comprehensive study by the Erasmus School of Economics and the University of Amsterdam tracked the results in Rotterdam, the first major city to implement the ban. The policy worked exactly as intended in one specific metric: investor purchases plummeted, and the share of homes bought by first-time homebuyers increased significantly.

However, the ban completely failed to lower housing costs. The researchers found that property values in the restricted neighborhoods remained virtually unchanged, ticking up by a statistically insignificant 0.1%.

More concerningly, the Dutch ban triggered a severe "waterbed effect" that actively harmed lower-income residents. Because homes were shifted from the rental market to the owner-occupied market, the supply of available rental units shrank.

As a result, rents in the restricted neighborhoods increased by 4%. The study concluded that the ban effectively acted as a gentrification engine: it helped middle-income households buy their first homes, but it did so by displacing lower-income renters who relied on the private rental market and could not afford a mortgage.

American economists warn that a federal ban could trigger the exact same dynamic in the United States. The Brookings Institution notes that owner-occupied and rental markets are inextricably linked; restricting the supply of single-family rentals inevitably drives up costs for families who either prefer to rent or do not have the down payment required to buy.

This is particularly relevant in Sunbelt cities like Atlanta, Charlotte, and Phoenix, where corporate landlords are heavily concentrated. While critics correctly point out that some corporate landlords have higher eviction rates and aggressively raise rents, they also provide a crucial service: allowing lower-income families to access high-opportunity neighborhoods, complete with better schools and lower crime rates, without needing a mortgage.

If the corporate ban is largely political theater, does the 21st Century Road to Housing Act actually do anything to lower costs? Financial analysts and housing experts say yes—but the real solutions are buried deeper in the 381-page bill.[2]

The legislation includes powerful supply-side reforms that address the actual root of the crisis: America simply has not built enough homes. The bill streamlines environmental reviews, cuts red tape that delays construction, and creates an innovation fund to financially reward municipalities that reform their restrictive zoning laws.[2]

It also updates a 1974 law to allow manufactured homes to be built without a permanent chassis, a technical change that could lower the cost of building a new unit by up to $10,000.[1][2]

Ultimately, the evidence suggests that the corporate buyer ban provides lawmakers with a populist victory, while the quieter regulatory reforms do the heavy lifting. Banning Wall Street from the housing market may change who gets to live in a specific house, but only building millions of new homes will make housing affordable for everyone.[2]
