The rise of Build-to-Rent housing

Brian Potter doesn't just track construction trends; he exposes the fragile economics behind a housing model that has quietly reshaped the American landscape. In a sector often dominated by anecdotal complaints about landlords, Potter offers a data-rich dissection of how the "build-to-rent" (BTR) industry evolved from a post-crisis emergency fix into a dominant force in new construction, only to face a sudden legislative cliff. This piece is essential listening because it reveals that the current standoff in Washington isn't just about ideology—it's about a potential freeze on tens of thousands of new homes that millions of Americans desperately need.

The Crisis That Built a Market

Potter traces the origins of this massive shift not to corporate greed, but to the catastrophic collapse of the 2008 financial crisis. He writes, "The modern BTR industry... is a product of the 2008 Global Financial Crisis." This framing is crucial; it reminds us that the scale of institutional ownership was a reaction to a market that had already imploded. Before the crash, single-family rentals were the domain of small, scattered operators. Potter notes that "as late as 2011, no single company owned more than 1,000 rental homes in the US." The explosion of large-scale ownership was a direct result of millions of foreclosures and a sudden tightening of credit that locked millions of Americans out of the mortgage market.

The rise of Build-to-Rent housing

The author highlights how the federal government actually encouraged this consolidation to stabilize the housing market. He points out that in 2012, the Federal Housing Finance Agency launched a pilot program that "allowed pre-qualified investors to bid on large portfolios of foreclosed properties owned by Fannie Mae." This historical context is vital. It suggests that the current political backlash against institutional investors ignores the fact that these entities were initially welcomed as a necessary shock absorber. Critics might argue that the government's role was short-sighted, but Potter's evidence shows a deliberate, if temporary, policy choice to prevent a total market collapse.

"The raft of foreclosures and the tightening of lending standards had two simultaneous effects on the housing market. First, they pushed millions of Americans into renting."

From Buying Distressed Assets to Building New Communities

As the market recovered, the strategy evolved. Potter explains that while early players like Invitation Homes focused on buying distressed properties, the industry eventually shifted toward constructing homes specifically for rental purposes. This transition was driven by economics: new homes meant lower maintenance and better management. Potter writes, "Being new construction, they typically had much lower maintenance costs than existing homes, and they could be designed by the developer with an eye towards minimizing maintenance and overheads."

This shift has led to a diverse product range, from detached homes with garages to "horizontal multifamily" developments that resemble spread-out apartment complexes. Potter observes that these developments are "designed by the builder to maximize rents and minimize overhead costs." While this efficiency drives profitability, it also raises questions about the long-term quality of life for tenants. Are these homes built for people, or for balance sheets? Potter suggests the answer is a mix, noting that companies like American Homes 4 Rent have reduced maintenance costs to just 25% of what they were in their purchased homes. However, this efficiency often comes with trade-offs, such as cheaper finishes and systematic property tax appeals, which Potter details with impressive specificity.

The Legislative Hammer

The piece pivots sharply to the present day, where the industry faces an existential threat from the Senate's 21st Century ROAD to Housing Act. Potter describes a provision in the bill that would force institutional investors owning more than 350 single-family homes to sell their BTR properties to individual homeowners after seven years. He writes, "Because BTR involves building a home and then retaining ownership of it to rent out, this provision threatens the fundamental business model of the BTR industry."

The immediate consequence, according to Potter, has been a near-total freeze in investment. "Since the announcement of this provision, funding for new BTR projects has virtually ground to a halt while investors wait to see whether the bill actually passes." This is the crux of the argument: a policy intended to increase homeownership may actually result in a net loss of housing supply. Potter cites over 100 pro-housing groups, including the National Association of Homebuilders, who argue the provision is "likely to significantly reduce housing supply in the short term."

The tension here is palpable. The administration's goal is to boost supply, but the mechanism chosen targets the very capital that has been filling the gap. Potter notes that BTR now accounts for more than 7% of new housing starts, up from less than 2% in the 1990s. To halt this growth is to ignore a significant portion of the nation's new housing pipeline. A counterargument worth considering is whether the long-term goal of breaking up large portfolios justifies the short-term pain of reduced construction. Yet, as Potter points out, the data limitations mean the true scale of the freeze could be even larger than the reported 68,000 homes.

"Funding for new BTR projects has virtually ground to a halt while investors wait to see whether the bill actually passes."

Bottom Line

Potter's analysis is a masterclass in connecting historical policy failures to current legislative gridlock. His strongest point is the demonstration that the BTR boom was a rational response to a broken market, not an anomaly. The piece's greatest vulnerability lies in its reliance on the assumption that institutional capital is the only viable path forward for this segment of construction; it offers little insight into how a fragmented market of small landlords might fill the void if the BTR model collapses. As the Senate debates this provision, the real cost won't be measured in political points, but in the thousands of homes that will never be built.

The rise of Build-to-Rent housing

A major shift in the housing market in the last several years is the rapidly increasing popularity of “build-to-rent” homes — single-family homes that are built specifically for the purpose of being rented out. According to the National Association of Homebuilders, build-to-rent homes have risen from less than 2% of new housing starts in the 1990s to more than 7% of housing starts today. In 2025, at least 68,000 new single-family housing starts were built to rent (and due to data limitations, the true number may be much higher, 100,000 homes or more).1

The build-to-rent, or BTR, industry has been in the spotlight recently because of a major federal housing bill, the Senate’s 21st Century ROAD to Housing Act. This bill, which is ostensibly designed to stimulate the building of new homes, includes a provision aimed at preventing large institutional investors from owning single-family homes. This provision, section 901, requires institutional investors (companies that own more than 350 single-family homes) to sell any build-to-rent homes to individual homeowners after seven years. Because BTR involves building a home and then retaining ownership of it to rent out, this provision threatens the fundamental business model of the BTR industry. Since the announcement of this provision, funding for new BTR projects has virtually ground to a halt while investors wait to see whether the bill actually passes. Over 100 pro-housing groups, including Berkeley’s Terner Center, the NAHB, and my colleagues at IFP have come out against this provision specifically, on the grounds that it’s likely to significantly reduce housing supply in the short term.

Because BTR has quickly become such a large fraction of new home construction and is now in the policy spotlight, it’s worth understanding the origins of the industry and why it has become so popular.

Origins of BTR.

The modern BTR industry, where developers build entire communities consisting of dozens or hundreds of single-family homes for rent, is a product of the 2008 Global Financial Crisis. Prior to the financial crisis, single-family home rental wasn’t uncommon — in 2005, there were over 8 million detached single-family homes being rented — but the business was mostly the purview of small “mom and pop” operators that owned a relatively small number of scattered rental properties. As late as 2011, no single company owned more than 1,000 rental homes in the US.

But the financial crisis shifted the housing landscape. Huge numbers ...
