The number of single-family built-for-rent (SFBFR) construction starts increased almost 16% in 2021, after a record-breaking third quarter for production. The SFBFR market is a way to add inventory amid concerns over housing affordability and downpayment requirements in the for-sale market, particularly during a period when a growing number of people want more space and a single-family structure. Single-family built-for-rent construction differs in terms of structural characteristics compared to other newly-built single-family homes, particularly with respect to home size.
According to NAHB’s analysis of data from the Census Bureau’s Quarterly Starts and Completions by Purpose and Design, there were approximately 15,000 single-family built-for-rent starts during the fourth quarter of 2021. Over the course of 2021, 51,000 such homes began construction, which is a 15.9% gain compared to the 44,000 estimated SFBFR starts in 2020.
Given the relatively small size of this market segment, the quarter-to-quarter movements typically are not statistically significant. The current four-quarter moving average of market share (4.5%) remains higher than the historical average of 2.7% (1992-2012) but is down from the 5.8% reading registered at the start of 2013.
Importantly, as measured for this analysis, the estimates noted above only include homes built and held by the builder for rental purposes. The estimates exclude homes that are sold to another party for rental purposes, which NAHB estimates may represent another three to four percent of single-family starts. Indeed, the Census data notes an elevated share of single-family homes built as condos (non-fee simple) in the fourth quarter, with this share standing at 4.5%. Many but not all of these homes will be used for rental purposes. Additionally, it is possible some single-family built-for-rent units are being counted in multifamily starts, as a form of “horizontal multifamily,” given these units are built on single plat of land. This possibility requires additional investigation but runs counter to the structural definitions used in the Census data.
With the onset of the Great Recession and declines in the homeownership rate, the share of built-for-rent homes increased in the years after the recession. While the market share of SFBFR homes is small, it has been trending higher. As more households seek lower density neighborhoods and single-family residences, a growing number will do so from the perspective of renting. This will be particularly true as mortgage interest rates increase. Thus, the SFBFR market will expand in the quarters ahead.
