The Changing Landscape of Housing:

Low-Density Rentals

June 28, 2021

By Todd LaRue, Managing Director , Cameron Pawelek, Vice President

RCLCO recently worked with the ULI Terwilliger Center for Housing to prepare Low-Density Rental Housing in America. The report highlights the emerging market segment of purpose-built and institutionally managed single-family rentals, including supporting demographic trends, an explanation of concepts and case studies, and operating metrics and conclusions.

This article summarizes some of the key topics of the ULI Terwilliger Center for Housing Report, including:

  • Demographic trends and affordability challenges leading to growth in the institutionalization of purpose-built single-family rentals
  • The evolution of the single-family landscape
  • Differentiating characteristics of various build-for-rent concepts and product types
  • Operating metrics and financials
  • Implications and conclusions regarding the single-family rental sector

Demographic Tailwinds

The United States is home to a broad spectrum of households with diverse housing needs; however, new rental deliveries in the past decade have primarily consisted of large-scale multifamily communities. Development patterns over the past decade have responded to existing structural and regulatory challenges, and the availability of debt for conventional multifamily properties further exacerbated rental housing’s uniformity.

Demographic shifts including the millennial cohort moving into prime family formation ages are a primary driver for growth in lower-density housing types. Given the constrained housing market and rising construction costs, the decline in homeownership affordability is one of the most pressing challenges facing many Americans, driving additional demand toward low-density rental housing. Today, the median home price is 5.6 times higher than the median income in the U.S., a significant change from the average of approximately 4.0 from 1985 to 2000. Additionally, the COVID-19 pandemic has created financial hardship for millions of American households and many may remain in the rental housing market for an extended period in the years to come.

The demographic tailwinds, the impact of COVID-19, and growing affordability concerns, which are highlighted in ULI’s 2021 Emerging Trends, contribute to the rapid institutionalization of a new rental housing product type: purpose-built, single-family rentals. While single-family rental homes are not a novel concept, as households have rented single-family homes for decades, purpose-built, single-family rental homes are a relatively new concept.

Single-family rentals (“SFR”) benefit from the maturing millennials seeking a new type of rental product that matches their changing lifestyles, empty nesters looking to downsize to a maintenance-free living option, and the array of households in transitional life stages. Given the strong tailwinds for purpose-built, single-family rental housing, many new players have entered or are considering the purpose-built single-family asset type. Furthermore, given the organic growth of the product type over the past 10 years, there is a wide variety of products, communities, and strategies, which increases confusion across the industry and the media regarding nomenclature. RCLCO and ULI have set out to codify the single-family rental market’s language, product types, and differentiating characteristics.

Defining the Landscape

The competitive landscape for institutionalized SFR housing continues a rapid evolution as more companies enter the asset class, each with various strategies, product types, positioning, and locations. Despite the significant variation in offerings already in the market, most market participants agree on the asset class’s overarching term: single-family rentals.[1] However, less of a consensus exists on the sub classifications. RCLCO and ULI analyzed hundreds of news articles and conducted interviews with various market experts to attempt to codify the language around the product type, which is detailed in the chart below:

Small-Scale Investors/Owners represent more than 97% of the existing SFR housing market, generally owning only a few properties and listing on online marketplaces such as Zillow. After the Great Financial Crisis, Institutional SFR Aggregators emerged and aggregated thousands of homes across various markets, utilizing robust platforms and economies of scale. This group has also started to work directly with builders to purchase blocks of homes to add to their portfolio as the inventory of resale homes has tightened. The newest group is the Purpose-Built SFR or Build-For-Rent (BFR) Community, where the entire community is planned and built as rental, and thus has consistent branding, housing quality, and often offers on-site resources such as leasing services, property management, and amenities.

Build-for-Rent Concepts

Within the BTR space there are also more subtle product distinctions based on unit mix, product type, and other factors. Horizontal multifamily, comprised of dense Single-family Detached (SFD) units, can achieve densities of nine to 14 units per acre, include private lawns/patios and a clubhouse with pool, and attract older millennials (pre- or early-family), downsizing empty nesters, those newly relocating to a market, and divorcees. RCLCO determined that 75% of this product type has been developed as infill development in established suburban locations, with the balance occurring in rapidly growing green field suburbs. Horizontal multifamily fills a product gap between traditional single-family homes and garden-style multifamily apartments. It attracts households that prefer a single-family home’s privacy but do not need or cannot afford the large square footages of traditional single-family homes. The main competition to horizontal multifamily is garden-style apartments, with some competition from SFA and SFD homes on the shadow market, and because this type is generally preferred to the alternatives, it commands a substantial pricing premium on a size-adjusted per square foot basis. Despite premium positioning, smaller unit sizes at horizontal multifamily communities typically produce lower monthly rent payments than the monthly cost of ownership within the same submarket.

Build-for-Rent Single-Family Attached housing encompasses a broad spectrum of community configurations, unit types, and sizes, though each unit shares at least one vertical wall, and units are not stacked on top of each other. Because SFA communities are located in urban and suburban settings, they have noticeable variations in project sizes and types, with densities of between eight to 16 dwelling units per acre (communities offering three-story townhouses able to achieve relatively high densities). Units at SFA communities generally provide two or more bedrooms and are larger on average than multifamily unit sizes but smaller than traditional single-family homes. In urban locations, there may be limited amenities, but newer suburban communities may have a clubhouse and pool. The market audience also varies by location, with urban infill communities attracting more young professional couples and roommates and some empty nesters, and suburban locations attracting more relocating families and pre family millennial couples. Given larger unit sizes and increased competition from the shadow market, BFR SFA communities are typically priced a slight size-adjusted premium over garden-style apartments, though premiums vary by quality and amenitization of the SFA community. Larger unit sizes and strong pricing typically yield monthly rent payments comparable to the monthly cost of ownership, assuming at least a 10 to 15 percent down payment.

Build-for Rent Single Family-Detached communities are the most similar to SFR units owned by institutional aggregators and small-scale investors but benefit from economies of scale with high concentrations of units in a single location and cohesive branding. Many of these communities are associated with or are sold from a larger master-planned community and have an average density of three to seven dwelling units per acre.

  • Given these lower densities, SFD communities are predominantly located in suburban locations and are typically platted as individual residential lots.
  • Units at SFD communities generally provide three or more bedrooms and are significantly larger on average than multifamily unit sizes, and have large fenced backyards.
  • Higher-end communities also typically have a pool and clubhouse, and those that are located within an MPC also are allowed access to the broader community amenity center.

The primary audience for BFR SFD homes is family households, typically in a transitional period after moving to a new market or during home construction, with mature professionals and empty nesters representing secondary market audiences. The majority of SFD communities are located in greenfield suburbs and the primary competition is inventory owned by institutional aggregators or small-scale investors. BFR SFD communities are typically priced at a slight size-adjusted premium over garden-style apartments, but at healthy premiums over small-scale investor inventory, given the elevated level of execution, on-site property management, yard maintenance, and amenities provided by the BFR communities. Larger unit sizes and strong pricing typically yield monthly rental payments comparable to the monthly cost of ownership, assuming a down payment ranging between 10 and 15 percent.

Operating Metrics

Property characteristics, target demographics, and locations vary across the SFR product classifications, resulting in differing project economics. Development patterns in recent years help illustrate the possible supportable land values, operating expenses, and investor appetite for the evolving land use. Density is often the most significant variable driving achievable land values, with horizontal multifamily able to pay higher land values in suburban infill locations due to their density, while BFR SFD typically compete with single-family for-sale developers in more suburban lower-density locations. Compared to traditional multifamily products, SFRs have historically enjoyed lower turnover because of “stickier” occupancy, lower overall maintenance costs due to limited common areas, and more upside in asset values. As a tradeoff, SFR investments require higher long-term capital expenditure requirements and upfront rehab costs (for existing homes). Historically, SFRs have achieved cap rates 20 to 50 basis points higher than garden-style apartments, but competition from potential investors has driven yields downward in the past year, with single-family cap rates now in line with traditional garden-style multifamily communities.

Implications and Conclusions

SFR housing has played an essential role throughout history in America, as large swaths of the U.S. population seek rental housing options other than high-density, multifamily properties. The trend toward purpose-built SFR housing has evolved over the past decade but has experienced exponential interest and growth over the past few years. As for many long-term trends, the outbreak of COVID-19 exacerbated and emphasized the need for a broader diversity of rental housing. Many of the key trends outlined in ULI’s 2021 Emerging Trends in Real Estate report, including the rise of working from home, a geographic shift to more affordable Sunbelt markets, growing demand in suburban neighborhoods, and the substantial and growing affordability crises, provide support for the investment thesis behind much of the growth in low-density rental housing.

The expansion and capitalization of low-density rental housing can deliver more housing at price points below the cost of purchasing homes within a respective neighborhood. However, there are some concerns that the institutionalization of the SFR housing market could have some unintended, adverse effects on affordability and equity issues unless public policy and developer responses address them as outlined in the report. While it is unlikely that low-density rental housing will solve the country’s substantial affordability crises, providing more housing alternates to meet the needs of a diverse array of American households is a positive step forward.


April, 2021


A question that we often hear is “How is technology and big data impacting the real estate industry?” We are aware that there are many emerging technologies and big ideas that are being pursued with the possibility to change, disrupt, or create new business models for real estate in the future. However, there are still data gaps given the lack of public reporting in the industry, which have slowed down the ability of technology to revolutionize the space. The biggest advances are being made by those who are active in the industry and can see where data and technology can make improvements from the bottom up, mitigating inefficiencies, improving operations, and optimizing utilization.

At RCLCO we wanted to share how we are utilizing data and technology in our work, by:

  • improving our existing methodologies and analysis,
  • expanding the ways we interact with clients and what a “deliverable” is, and
  • partnering with others in the industry who are utilizing data and analytics in new ways.


When seeking to become a more data-driven company, the first step is not to gather data and then run analyses to see is something useful or relevant comes out. What makes data science most effective is when a company identifies an opportunity or challenge within their business, and then structures a targeted question that data can answer to further their overall business strategies and priorities. What follows are the results of using data to respond to specific objectives within the real estate industry.

Neighborhood Classification

The first tool is RCLCO’s Neighborhood Atlas, which is an interactive visualization of U.S. suburban and urban neighborhoods which was developed to complement work done by ULI’s Terwilliger Center for Housing. This tool was created to help define, at a more specific level, the distinction between different types of neighborhoods that previously fell under the more broad ‘urban’ or ‘suburban’ classifications. For example, in a city like Washington, D.C. there are areas within the city limits (AU Park or Takoma) that qualify as established or stable suburbs, and areas further out in neighboring Virginia (Reston Town Center and Tysons) that qualify as urban emerging economic centers.

You can actively explore the neighborhood atlas just like any other online map, easily identifying the classification for neighborhoods where you live, work, play, or may be planning a real estate development.

Performance Tracking Pre- and Post-Pandemic

The second tool is an interactive dashboard tracking urban and suburban apartment market performance over the Covid-19 pandemic. This tool allows for the comparison between metro areas or between neighborhood types within a metro. The tool also includes metrics such as effective rent and occupancy, and suggests that there is some nuance to the more binary statement that suburbs have outperformed urban areas.

In Atlanta, for example, urban rents dropped overall, though stable and challenged residential neighborhoods saw rents increase during the same period that high-end neighborhoods, mixed-use districts, and economic centers saw effective rents drop. In most areas you can also expand the timeline to look back pre-pandemic.

Interactive Reports for Clients

The third example we shared in our webinar was of a sample dashboard, representing the type of custom deliverable we have begun to create for our clients who are interested in geographic expansion analyses, and responds to highly targeted questions tailored to each client’s unique business strategy. Data can be collected on factors, including household growth, potential rent upside, growth/share of key employment industry sectors, top of market rent levels, and many other factors, which can be weighted based on a company’s specific expansion criteria.

In these analyses, we look at data on the metro and submarket level and create a proprietary scoring methodology that allows us to prioritize and rank submarkets. This dashboard allows the client more functionality than a static PDF report, as they are able to run and adjust scenarios as they see fit and visualize the information instantaneously. The below is a screenshot of this analysis, but please watch our webinar to see an interactive demonstration.


As a final example, RCLCO has partnered with Cecilian Partners, a customer experience company that created an innovative proptech offering called The XO, which delivers a faster, better experience to the home buyer and simplifies operations for home builders and developers. This software provides high-quality, up-to-the-minute data at the community level, which results in higher visibility and insights into sales and operational information, data which previously was often provided piecemeal and with months of lag time.

We at RCLCO are excited by these tools that we have shared, and by the possibility of tools that are still under development. We hope that this overview helps illuminate a little bit about where RCLCO is headed, and also may provide some ideas for where there may be opportunities for utilizing technology in your own business. If you would like to utilize these tools, feel free to email Kelly Mangold at kmangold@rclco.com.



Population growth rates in urban places are approaching suburban growth rates for the first time in decades.

Between 2000 and 2015, the population of urban places increased by only 1%, well below the 13% population growth seen in suburban places. However, urban and suburban places grew at roughly the same rate between 2010 and 2015. During this time, denser urban locations grew significantly faster than more residential neighborhoods, suggesting that new urban residents are demonstrating a preference for mixed-use environments.

Today, more than 29 million Americans live in
Urban neighborhoods.

This figure represents 17% of the total population in just 1% of the land area in the 50 largest metropolitan statistical areas (MSAs). Three-quarters of these urbanities live in somewhat dense but predominantly residential neighborhoods, contrary to popular perception and most media attention focused on true mixed-use places.

Urban places are now capturing more than their
fair share of new job growth.

In the 50 largest MSAs, urban places accounted for 30% of existing jobs and 36% of new job growth between 2005 and 2015. Contrary to popular belief, the suburbs are experiencing job growth too, at rates that are nearly equal to the job growth seen in urban places. But, downtowns are booming, and the job base in established urban employment cores—referred to as Economic Centers in this report—increased at a faster rate than the number of jobs in any other type of neighborhood during this time.

Upscale urban places are among the most
racially and ethnically diverse types of neighborhoods.

Although the majority of minorities live in the suburbs and many economically challenged urban neighborhoods are predominantly nonwhite, upscale urban places are often more diverse than similarly high-end suburbs. In fact, there is close to a 50/50 split between the white and non-white populations in Economic Centers and Mixed-Use Districts, the two urban neighborhoods where average rents are highest.

Almost a third of Urban households are headed
by Millennials.

While the majority of these younger households live in suburbs, more than 29% of households in urban locations are under the age of 35, relative to only 18% in the suburbs. Within urban places, young households are disproportionately more likely to gravitate toward dense neighborhoods with a mix of uses.

Rental apartment development is now
concentrated in Urban locations.

Between 2010 and 2017, the rental apartment inventory in urban places grew twice as fast as the inventory in the suburbs, by 32% compared with 16%. During this time, Emerging Economic Centers accounted for one-fifth of new apartment units, despite representing only 6% of the overall apartment inventory in 2010. On the other hand, more residential urban places accounted for less than their fair share of new units; during this same time period, Stable and Challenged Neighborhoods accounted for only 8% of new units, despite representing 43% of the inventory in 2010.

Urban locations tend to face greater affordability
issues than the suburbs.

Urban places have an average household income of $66,000, relative to $89,000 for the suburbs. However, the average monthly rent of a multifamily apartment in urban places is $1,650, well above the $1,275 seen in the suburbs; likewise, the average home value is more than $50,000 higher in urban places. These differences highlight the issues of affordability that are prevalent in many urban places. In particular, residents who live in dense, mixed-use neighborhoods—such as Economic Centers and Mixed-Use Districts—tend to pay more of their incomes for housing.

Roughly half of Urbanites take transit, walk, bike,
or carpool to work.

Just over 50% of workers living in urban locations drive alone to work, compared with 78% of workers living in the suburbs. In particular, people who live in Economic Centers and Mixed-Use Districts are more likely to use alternative transportation methods, as only 32% and 35% of the workers who live in those respective places drive to work alone every day.
