Rising Popularity of Variable and Tracker Mortgages: What London Landlords Need to Know

Variable and tracker mortgages have more than doubled in popularity in the last six months, driven by sharply higher fixed rates. This shift means landlords should prepare for potential fluctuations in tenant payment reliability and reassess affordability criteria accordingly. We outline practical steps landlords can take now to manage the risks and adapt their strategies.

Why Variable and Tracker Mortgages Are Gaining Ground

Recent data from Mortgage Solutions highlights a significant rise in borrowers opting for variable and tracker mortgage products, with usage more than doubling over the past six months. This trend is largely a response to fixed mortgage rates climbing sharply, pushing borrowers towards shorter-term fixes or variable options offering lower initial rates but greater exposure to future interest rate rises.

What This Means for Landlords

For private landlords, particularly in London’s competitive rental market, this development matters because tenants with variable or tracker mortgages may face fluctuating monthly payments as interest rates change. This can impact their financial stability and, by extension, their ability to pay rent reliably.

  • Payment Stability Risks: Tenants’ mortgage repayments could increase if Bank of England base rates rise, potentially tightening household budgets.
  • Affordability Considerations: Traditional affordability assessments based on fixed repayments may no longer fully capture tenant risk.

Different Landlord Profiles and Impacts

  • Single-Unit Landlords: May experience occasional payment delays or requests for rent flexibility if tenants’ mortgage costs rise unexpectedly.
  • HMO Landlords: With multiple tenants, risk is somewhat diversified but vigilance remains crucial.
  • Portfolio Landlords: Larger portfolios might see a noticeable trend in arrears linked to rising mortgage costs, affecting cash flow.
  • Accidental Landlords: Those less experienced in tenant financial risk assessment should be particularly cautious.

Practical Steps Landlords Should Take Now

  1. Monitor Tenant Payment Patterns Closely: Use your rent collection data to spot early signs of payment stress.
  2. Review Tenant Affordability Assessments: When vetting new tenants, factor in the possibility of variable mortgage repayments affecting their finances.
  3. Engage in Open Tenant Communication: Encourage tenants to inform you proactively about financial difficulties.
  4. Stay Updated on Interest Rate Trends: Keep an eye on Bank of England announcements and mortgage market reports to anticipate further shifts.
  5. Consider Rent Guarantee Insurance: This can offer protection against potential payment disruptions.

Conversations and Workflow Adjustments

  • Schedule periodic tenant check-ins focused on financial wellbeing.
  • Work with letting agents to enhance tenant vetting protocols reflecting current mortgage market conditions.
  • Review your rent review and arrears management processes to ensure responsiveness.
