Navigating an Unusually Active Mortgage Market: What London Landlords Need to Know in Early 2026

An Unusually Active Market: What Has Changed?

The mortgage intermediary sector kicked off 2026 with remarkable activity levels, according to Mortgage Solutions. This heightened engagement stems mainly from geopolitical unrest — notably the conflict involving Iran — which has unsettled swap rates and elevated inflation expectations. In practical terms, many borrowers have expedited remortgage and purchase decisions to secure favourable terms before further market shifts.

Alongside these external factors, the Financial Conduct Authority (FCA) has updated its guidance on affordability. These regulatory changes permit some borrowers to access higher loan amounts, effectively expanding borrowing capacity and supporting increased market volume.

Why This Matters for Landlords

These developments carry significant implications for London’s private landlords, especially when it comes to tenant behaviour, financial stability, and compliance:

• Accelerated Borrowing Behaviour: Tenants who recently increased borrowing or remortgaged may experience altered cash flow dynamics, influencing their ability to sustain rental payments or comply with lease terms.

• Affordability Assessments: Letting agents and landlords must be attentive to the FCA’s updated affordability criteria. This impacts how tenant financial eligibility is assessed, particularly for those linked to mortgage-backed properties.

• Market Volatility and Tenant Demand: Geopolitical and economic uncertainty may affect tenant confidence and demand patterns, potentially increasing tenancy turnover or modifying rental price sensitivity.

Impact Across Landlord Profiles

• Single-Unit Landlords: May notice changes in tenant application profiles, requiring more thorough vetting to understand the borrower's recent mortgage activities.

• HMO Landlords: With multiple tenants, risk diversification exists, but overall tenant financial stability remains crucial. Increased mortgage market volatility could influence the collective affordability of tenants.

• Portfolio Landlords with Mortgage-Backed Properties: Must carefully monitor how changes in borrower remortgaging affect lease agreements and the security of rental income.

• Accidental Landlords: Might be less prepared for these market nuances and should focus on gaining clarity around tenant financial profiles and compliance obligations.

Practical Steps Landlords Should Take Now

1. Revise Tenant Vetting Procedures: Incorporate questions about recent remortgage or borrowing activity to better gauge financial resilience.

2. Stay Informed on FCA Guidance: Regularly review FCA updates on affordability to align tenant eligibility assessments with current standards.

3. Engage Mortgage Intermediaries: Open lines of communication with brokers or intermediaries to grasp current borrower sentiment and market trends, which can inform tenancy negotiations.

4. Monitor Geopolitical Developments: Keep abreast of global events that might impact economic stability, enabling proactive adjustments to rental strategies.

5. Review Lease Agreements: Consider clauses that account for tenant financial changes or market volatility to mitigate arrears or early terminations.

Looking Ahead: Strategic Planning for Property Teams

For property managers and teams, this period demands heightened risk awareness and strategic foresight. Establish workflows to review tenant financial health more frequently and coordinate with mortgage professionals for early warnings of tenant instability. Planning now reduces exposure to unforeseen rent defaults or vacancy risks due to shifting borrower circumstances.
