There are 6.2 million privately rented households in the UK, with just over half living in suburban markets. Single-family housing (SFH) is cementing its position as a key component of the build-to-rent market, accounting for 55% of total investment over the last year, the first time it has overtaken multi-family as the largest segment of the BTR market by capital deployed.
What was once a niche asset class, dominated by a handful of investors, is now reshaping the living sector. By March 2025, 14,000 homes had already been delivered, with a further 13,000 under construction, signalling the sector’s transition into a mainstream institutional investment class.
For many investors, single-family housing is an obvious next step, offering diversification, lower churn and predictable returns. With a large target market – around 60% of private renters in the UK already live in houses – interest is growing. But demand continues to outpace supply. Investors need scale and partnerships to unlock delivery, and those early adopters will win.
Demand vs execution
There has been a strong upward trend in single-family housing capital, with over £5bn invested in SFH schemes since 2023. Furthermore, 71% of living sector investors plan to expand into SFH in the next five years, showcasing a strong appetite.
In the US, the build-to-rent and single-family rental market is vastly more mature, with institutional investors owning millions of properties. According to AEI, homes in BTR communities in the US represented 30% of acquisitions by institutional investors in 2024. The UK is at an early stage of the same journey, which is why investors who establish themselves in the suburban market will win.
The US build-to-rent and single-family rental market is vastly more mature, institutional investors own millions of homes there. The UK is at an early stage of the same journey, which is precisely why early movers have an advantage. A brief reference to this would give readers a sense of the long runway ahead and validate the asset class for investors less familiar with it.
But execution can be difficult and expertise is key. Recently, it was announced that retailer John Lewis had backed out of its plan to enter the BTR market, blaming higher interest rates, inflationary pressures and a more cautious property market meaning that the model no longer meets the partnership’s investment criteria.
Single-family housing is operationally different. Whilst multi-family is often amenity-led, SFH focuses on the quality of a family home, resulting in lower operating costs. The asset class also attracts a different kind of tenant – one that is more likely to want to stay in one place – driving a lower churn rate. With the addition of the upcoming Renters’ Rights Act, scrapping ‘no-fault’ evictions, single-family housing is already leading the way and will only become more attractive to renters as private landlords exit the market and mortgage rates continue to remain high and even rise.
The SFH model also plays directly to the strengths of SME housebuilders, enabling them to forward-sell units, recycling capital more quickly and allowing new communities to come to life sooner, creating genuine win wins for investors and developers. When considering the Government’s continued focus on housebuilding, which aims to accelerate the delivery of 500,000 new homes by unlocking private investment and supporting SME builders, it’s not a question of if capital is available – it’s about having the playbook and partnerships to be able to execute.
Building a model, not just a portfolio
If suburban single-family housing is to move from an emerging piece of the puzzle to a core part of the UK’s housing model, strategic execution becomes the differentiator. Over the last 10 years, Sigma Capital has shown how institutional SFH can be delivered at scale, not by relying on completed homes, but by creating new supply.
Since launching the UK’s first single-family rental fund, Thistle Investments, Sigma has delivered almost 11,000 homes across four investment vehicles, demonstrating that scale in suburban SFH is achievable, but only when operational efficiency and capital align.
A key distinction in Sigma’s approach has been forward-funding and partnering with housebuilders to deliver purpose-built homes for rent, rather than acquiring stock, contributing to net-new housing supply. This is critical in a traditionally undersupplied market – families were often priced out of homes for open-market sale and private rents were in short supply. Sigma’s model created a blueprint for performance to be built in, working directly with housebuilders to design specifications, reducing long-term operational challenges.
Suburban SFH should never be treated as a portfolio-building exercise, but rather a mature operating model that can drive long-term, stable returns for investors.
What comes next?
Whilst investment volumes in single family housing are rising, reflecting strong demand and shifting demographics, institutional capital must continue to grow, as it currently only represents a small share of the market. s. An estimated 3.2 million private renters already live in such areas. The scale of the opportunity for institutional investors to deliver suitable housing options for these households is huge. For investors already active in the multifamily market, SFH gives them exposure to different geographies and a diversified demographic.
It’s no longer about questioning if single-family housing is viable, but rather, who has the right model to be able to execute. SFH is shaping the living sector – and in a world of higher interest rates and difficult mortgage affordability, investors can take advantage of a solution to not only their own returns on capital, but to the wider housing crisis.
