Why Buying Still Beats Renting Despite Rate Uncertainty: What London Landlords Need to Know

Buying Remains Cheaper Than Renting — What This Means for Landlords

Recent analysis by TwentyCi highlights that buying a property in the UK still costs on average £500 less per month than renting, with London savings nearing £1,000 monthly—even amid rising mortgage rates and economic uncertainty in early 2026. Rents now consume a record 45.5% of median disposable income, intensifying affordability pressures on tenants.

For landlords, this continuing cost advantage for buyers signals potential tenant motivation to purchase rather than renew leases, increasing turnover risks and necessitating careful rental pricing strategies.

Shifts in Mortgage Lending: Higher Income Multiples and What They Imply

Major lenders like Nationwide, Halifax, and Barclays have increased income multiples from approximately 4.5–5x to 5.5–6x salary for mortgage approvals. This supports buyers with strong credit profiles despite rising rates but also narrows access for some, especially first-time buyers or those with lower credit scores.

Landlords should note:

• Potential buyer pool narrowing: Higher multiples restrict access for some buyers.
• Changing tenant demographics: Demand may shift toward higher-income renters or those unable to meet stricter lending criteria.

Portfolio landlords and letting agents should incorporate these lending dynamics into market outlooks and tenant discussions.

Transaction Times Are Lengthening — Plan for Delays

Average times to exchange property sales have risen to 134 days due to increased listings and complex mortgage processing in a higher-rate environment.

Implications for landlords:

• Longer tenant move-ins and sales completion: Prepare for extended void periods.
• Process efficiencies needed: Collaborate with agents using digital tools to streamline transactions and reduce mortgage offer expiry risks.

Managing these timelines proactively helps maintain stable occupancy and income flow.

Practical Steps for Landlords

1. Monitor rental affordability and tenant behaviour: Track local trends to anticipate demand shifts or tenant turnover linked to buying incentives.
2. Review portfolio financials: Consider impacts of rising income multiples and delayed transactions on investment and refinance strategies.
3. Engage with tenants and agents: Address affordability openly; consider flexible lease terms or rent reviews aligned with tenant capacity.
4. Digitise property management workflows: Adopt digital platforms for lettings and sales to minimise delays and improve communication.
5. Update advising materials: Ensure tenant and landlord communications reflect current lending criteria and market conditions.

Tailoring Strategies by Landlord Profile

• Single-unit landlords: Focus on retaining tenants with competitive rents and transparent communication.
• HMO operators: Monitor turnover risk carefully and diversify tenant mixes to reduce vacancies.
• Portfolio landlords: Use data analytics to benchmark local markets and adjust acquisition or disposal plans.
• Accidental landlords: Seek professional advice for refinancing or portfolio consolidation considering lending changes.
