The Houses in Multiple Occupation (HMO) sector continues to demonstrate strong momentum in 2025, buoyed by robust fundamentals and particularly pronounced growth in the student rental market. Recent data from StuRents reveals that 77% of British students prefer HMO accommodation over Purpose Built Student Accommodation (PBSA), with the HMO sector experiencing rental growth exceeding 5%. This strength is underpinned by an influx of 160,000 UK undergraduates since 2016, reinforcing a substantial domestic market with sustained demand. The positive long-term demographic trends combined with constrained affordable supply underpin the sector’s rental growth prospects.

This growth is reflected in wider HMO market dynamics, where rental yields have shown a consistent upward trend. According to broader market analysis, average HMO rental yields stand at around 8.5% in 2025, up from 8.1% in 2023, making it an attractive option for investors seeking higher returns. This is corroborated by reports that professional landlords are capturing some of the highest yields in the sector, with average yields reaching 7% according to recent landlord trend surveys. Higher rental yields are partly driven by landlords implementing rent increases linked to property upgrades, indicating a willingness among tenants to pay for enhanced accommodation standards.

The HMO market’s size and financial significance further validate its importance within the wider UK property landscape. Research estimates the English and Welsh HMO market to be valued at £78 billion, generating over £6.3 billion in annual rental income. With approximately 182,554 HMO properties, of which nearly three-quarters are small HMOs shared by three to four tenants, the market is a major contributor to residential rental supply. London holds the lion’s share, accounting for 33.9% of all HMOs, while other top investment locations include Manchester, Liverpool, Leeds, and Birmingham. These cities are seeing notable trends, such as refurbishment booms and expanding student populations, further bolstering demand.

Yet, the sector faces potential regulatory challenges with the forthcoming Renters Rights Bill, which could significantly alter market dynamics, particularly in the student segment. Industry experts gathered by StuRents suggest the Bill might "profoundly shift the seasonality in the HMO market," enabling PBSA developments to target displaced domestic demand during traditional HMO booking periods. However, the affordability gap between PBSA and HMOs remains wide, with PBSA often priced beyond the average domestic student’s budget, maintaining HMOs as the preferred and more accessible option for many.

Investor sentiment remains strong amid these evolving market conditions. While international student demand has held steady for many portfolios in 2025, the broader demographic outlook for HMOs remains positive, supported by a continued influx of both domestic and international tenants. In markets with strong university ties and appropriate pricing approaches, international demand is expected to further underpin sector growth.

Operational considerations also play a role in the current HMO landscape. Rising running costs—up around 4% year-on-year due to inflation and enhanced compliance requirements—are tempered by a reduction in tenant turnover, suggesting longer tenancies and greater income stability for landlords. Compliance and licensing are increasingly becoming focal points, with a 6% year-on-year increase in HMO licenses signalling greater market participation and regulatory adherence. This backdrop calls for strategic investment and management approaches to optimise returns while navigating compliance.

In summary, the UK’s HMO sector in 2025 presents a compelling proposition for investors, characterised by strong rental yields, growing demand from students and young professionals, and resilient market fundamentals. While regulatory changes and cost pressures pose challenges, the sector’s scale, demographic dynamics, and geographic hotspots contribute to sustained confidence. With strategic positioning and careful management, HMOs remain a key segment within the UK’s residential rental market, continuing to attract significant interest from landlords and investors alike.
