Rising rents contrast with steep mortgage rates deterring landlords
The average rent outside London has hit a record £1,418 pcm, yet rising mortgage rates are making buy-to-let investment less attractive, according to Rightmove data and market analysis.
Rents across the UK outside London have reached an all-time high, with the average advertised rent now standing at £1,418 per calendar month, Rightmove reports. London rents have surged even further, reaching a new record average of £2,825 pcm. Despite these increases, the attractiveness of investing in rental properties is being undermined by sharply higher mortgage rates, which have risen significantly since geopolitical tensions escalated earlier in the year.
The rental market shows signs of stabilisation compared with the rapid growth seen between 2021 and 2023, when annual rental price increases hovered around 10%. Currently, the supply of rental homes is slightly down by 2% compared to last year, and renter demand has also decreased by a similar margin nationally. This balance tempers the upward pressure on rents, although London’s market remains tighter, with a 9% drop in available rental homes and a 6% increase in renter demand.
Rightmove data highlights regional rental dynamics and landlord activity
London’s rental market is experiencing faster growth than the rest of Great Britain, with annual rental growth accelerating to 3.2%, outpacing the 2.4% rise outside the capital. This is attributed to a pronounced supply squeeze in London, where fewer homes are available to rent and fewer new listings are entering the market. Employment patterns and office return requirements are also drawing renters back to the capital.
Outside London, rents are rising more rapidly in traditionally cheaper areas, where there is more room for growth. However, the overall number of homes available to rent has declined slightly, reflecting a constrained supply environment. At the same time, landlord selling activity has remained relatively stable, with around 13% of homes for sale having been previously available for rent, a small increase from 12% last year. Conversely, the proportion of rental homes that were previously for sale has decreased from 17% to 15%, indicating a reduction in new landlord investment.
Buy-to-let mortgage rates have increased substantially, with the average two-year fixed rate now approximately 5.34%, compared to 4.16% before the recent geopolitical conflict involving Iran. This rise in borrowing costs is making property investment less financially viable, especially in areas where capital growth prospects are limited. The higher cost of finance is a significant factor deterring prospective landlords from entering or expanding in the market, despite the upward trend in rental income.
Contextualising the current rental market and investment challenges
The UK rental sector is navigating a complex environment where tenant demand and rental prices remain robust, but landlord investment is constrained by rising financing costs. The post-pandemic rental cycle has seen fluctuations, with London initially experiencing rent declines as tenants left the city, followed by a rebound as renters returned. More recently, affordability issues shifted rental growth momentum outside London, but the latest data suggests London is regaining rental price growth strength.
Landlords face a challenging calculus: while rental income is increasing, the cost of servicing buy-to-let mortgages has risen sharply. This squeeze on yields may lead some landlords to reconsider their portfolios, potentially reducing the supply of rental properties further. The balance between rental income and mortgage costs is critical, especially for smaller landlords or those with limited capital reserves.
Additionally, regulatory and compliance requirements continue to evolve, adding operational complexity and costs for landlords and letting agents. These factors collectively influence decisions around property acquisition, retention, and rental pricing strategies.
Practical implications for landlords and letting agents
For landlords, the current market conditions mean careful financial planning is essential. Higher mortgage rates reduce net rental yields, so landlords must reassess affordability and profitability when considering new purchases or refinancing existing loans. Those with fixed-rate mortgages may be insulated temporarily but should prepare for potential future increases when rates reset.
Letting agents should be aware of the supply constraints and rental price pressures, advising landlords accordingly. They may also see changes in landlord behaviour, with some opting to sell properties or delay investment decisions. Agents can play a role in helping landlords optimise rental income through effective marketing, tenant retention, and compliance with evolving regulations.
Both landlords and agents should monitor local market conditions closely. In London, the tighter market and rising rents present different challenges and opportunities compared to other regions. Understanding regional variations will be important for portfolio management and client advice.
Uncertainties and what to watch going forward
Looking ahead, the trajectory of mortgage rates remains uncertain, influenced by broader economic and geopolitical developments. Any further increases could exacerbate the affordability squeeze for landlords, while a stabilisation or reduction might encourage renewed investment.
Government policy changes related to rental regulation, tax, and landlord licensing could also impact the sector. Landlords should stay informed about potential reforms that might affect operating costs or tenancy arrangements.
Tenant demand patterns may shift in response to economic conditions, employment trends, and housing supply. Monitoring these factors will be crucial for landlords and agents to adapt strategies effectively.
Key considerations for landlords now
- Review current mortgage arrangements and assess the impact of rising rates on rental yields and cash flow.
- Keep abreast of local rental market trends, particularly supply and demand dynamics in your area.
- Ensure compliance with all regulatory requirements, including safety standards and tenancy law changes.
- Consider the potential for rent increases where market conditions allow, balanced against tenant affordability.
- Evaluate portfolio strategy in light of financing costs, potential capital growth, and operational expenses.
- Engage with letting agents to optimise property marketing and tenant management.
