NatWest Raises Loan-to-Income Ratio to 6.5 for High Earners: What London Landlords Need to Know

NatWest has raised its maximum loan-to-income (LTI) ratio to 6.5 for joint applicants earning £150,000 or more, allowing borrowing up to 75% loan-to-value (LTV). This change could impact tenant demand in London’s rental market, especially among higher earners likely to consider buying. This article explains the update, its implications for different landlord profiles, and practical steps landlords can take to adapt their strategies effectively.

What Has Changed?

NatWest has increased its maximum loan-to-income (LTI) ratio to 6.5 for joint applicants with combined incomes of £150,000 or more. This means these borrowers can now secure mortgages up to 6.5 times their annual income, with a loan-to-value (LTV) up to 75%.

This is NatWest’s fourth LTI adjustment in 2024, aimed at supporting high-earning buyers in expensive areas like London by improving borrowing capacity.

Why Does This Matter to Landlords?

Higher LTI ratios for affluent buyers can affect London's rental market in several ways:

  • Potential Reduction in Rental Demand: Tenants who can now borrow more may choose to buy rather than rent, particularly in mid-to-high-end segments.
  • Market Segmentation Impact: This primarily influences higher-end rental markets serving professionals and dual earners.
  • Shift in Tenant Profile: Landlords may see changes in tenant enquiries and turnover, especially near price points accessible to these buyers.

Impact on Different Landlord Profiles

  • Single-Unit Landlords: May face longer void periods or more competition from buyers in prime London locations.

  • HMO Landlords: Likely less impact here as these properties often serve students or lower-income professionals.

  • Portfolio Landlords: Should monitor sales activity closely; some tenants might become buyers, potentially creating opportunities to adjust rents or target new demographics.

  • Accidental Landlords: May experience changing tenant demand patterns that affect income stability.

Practical Steps for Landlords

  1. Review Local Market Data: Use property portals and estate agents to track sales and rental enquiry trends.
  2. Engage with Mortgage Brokers: Understand how lending changes impact local buyer behaviour.
  3. Adjust Marketing Strategies: Emphasize features attractive to tenants remaining in the rental market; consider flexible leases.
  4. Screen Tenants Diligently: Maintain thorough screening to reduce voids and arrears.
  5. Evaluate Rent Pricing: Be open to modest rent adjustments or offering added value if demand softens.
  6. Consider Portfolio Review: For multiple properties, think about repositioning or selling in response to market shifts.

What to Watch Next

  • Changes in other lenders’ LTI policies.
  • Regional affordability and property price trends.
  • Government policy updates on mortgage lending and rental regulations.
