The Buy-to-Let (BTL) sector has been through a period of significant adjustment – rising interest rates, evolving tax treatment, and tighter regulation have all reshaped the landscape. But as we move through 2025, signs are emerging that the tide may be turning, offering fresh opportunities for landlords ready to take a strategic approach.

The Market Shift: From High Rates to Stabilisation

After a sustained period of rate hikes, driven by inflationary pressures, we’re now entering a more stable and potentially softening interest rate environment. With inflation showing signs of control and unemployment rising, markets are increasingly pricing in a Bank of England base rate cut – possibly as early as August, with expectations of a 25bps reduction.

This has already begun to feed into selective lender repricing, especially for lower-risk borrowers and well-leveraged portfolios.

For BTL investors, this opens the door to:

  • More favourable remortgage options
  • Reduced stress testing thresholds
  • Opportunities to release equity or consolidate

Current BTL Lending Conditions

Despite earlier tightening, the BTL finance market remains competitive – especially for experienced landlords and those with strong rental coverage. Key trends we’re seeing:

  • Interest rates from ~4.75%–6.25% depending on LTV, product type, and property class
  • Rental cover stress testing easing slightly on 5-year fixed products
  • Specialist lenders offering flexibility for HMOs, MUFBs, and limited company borrowers
  • Green mortgages gaining traction for energy-efficient properties

Portfolio landlords, in particular, are finding increased lender appetite, especially when refinancing or expanding in areas with solid rental demand and capital resilience.

Strategic Moves for Landlords

With yields under pressure and costs rising, many landlords are asking: Is it still worth investing in BTL?

The answer depends on strategy. We’re seeing successful landlords:

  • Refinance to release equity for new purchases or upgrades
  • Consolidate borrowing across portfolios for better terms
  • Regear portfolios away from underperforming stock
  • Invest in higher-yielding units such as HMOs or semi-commercial assets
  • Use limited companies to optimise tax efficiency

With capital values in many regions still stabilising, there’s a window for well-capitalised investors to make counter-cyclical acquisitions—especially where seller motivation is high.

How We Can Help

At Mortimer Street Capital, we act as strategic advisors – not just brokers. We work with over 200 lenders, including high-street banks, challenger lenders, and specialist BTL funders, to:

  • Secure the most appropriate funding—on interest-only, fixed, or geared terms
  • Structure portfolio refinances for cash flow and leverage efficiency
  • Assist with complex cases (e.g. offshore entities, SPVs, mixed-use, etc.)
  • Identify funding opportunities as rates soften and lender appetite shifts

Final Word

2025 is a year of recalibration for the BTL sector. The era of ultra-cheap money may be behind us, but the fundamentals of demand-driven rental markets remain strong. With lenders showing early signs of repricing and competition quietly heating up, this may be the time to act – not wait.

Whether you’re refinancing, expanding, or reassessing your strategy – now’s a smart time to review your options.
