UK Mortgage Lending Surges to 2021 Levels: What London Landlords Need to Know Now

Lending Growth in 2025: By the Numbers

UK Finance data for 2025 reveals a marked increase in mortgage lending for home purchases, with loan numbers up 16% and gross lending value rising 20% compared to the prior year. Lending to first-time buyers grew by 18%, reflecting easing lending criteria, yet affordability challenges remain significant. Refinancing activity also climbed, mortgage arrears fell, but repossessions increased, indicating some underlying financial stress.

Why This Matters to Landlords

A surge in mortgage lending, particularly among first-time buyers, can influence the rental market in multiple ways:

  • Tenant Mobility: Easier mortgage access encourages tenants to purchase homes, potentially increasing rental property turnover.
  • Rental Demand Fluctuations: While some renters transition to ownership, affordability pressures may sustain or even heighten demand in certain rental segments.
  • Affordability Risks: Financial strain on buyers may heighten tenant arrears or defaults risks.
  • Mortgage Cost Pressures: Rising refinancing suggests landlords may face shifting mortgage costs, affecting cash flow, especially those with variable or short-term deals.

What Different Landlord Profiles Should Consider

  • Single-unit & Accidental Landlords: Prepare for higher tenant turnover and ensure tenant screening and affordability checks capture current market realities.
  • HMO Operators: While tenant churn might increase, HMOs often serve demographics less likely to purchase immediately; maintain strong rent collection and arrears monitoring.
  • Portfolio Landlords: Exposure to refinancing risks requires active mortgage management—consider remortgaging or fixing rates while factoring in costs.

Practical Next Steps for Landlords and Property Teams

  1. Review Affordability Assessments: Refresh tenant affordability checks with up-to-date income and employment data; factor in local labour market variability.

  2. Monitor Tenant Financial Health: Implement early-alert systems for payment difficulties using rent tracking tools and maintain proactive communication.

  3. Plan for Increased Turnover: Optimize marketing and property turnaround to reduce void periods when tenants transition to homeownership.

  4. Assess Mortgage Exposure: Consult mortgage brokers regularly to evaluate refinancing options and secure favourable rates.

  5. Stay Attuned to Market Data: Monitor local repossession and arrears trends to anticipate tenant risk shifts.

Strategic Planning Amid Affordability Pressures

With forecasts of slowed lending in 2026 due to affordability, landlords should prepare for a stabilising or softer rental market by:

  • Conducting scenario planning to model rental income under varying occupancy and arrears conditions.
  • Diversifying tenant profiles or property types to mitigate risk.
  • Maintaining contingency funds to manage potential cash flow gaps.
