The buy-to-let landscape has shifted significantly in recent years. Tax changes, stricter lending criteria, and evolving tenant demand have made expert advice more important than ever. This guide covers everything landlords and aspiring investors need to know in 2025.
Section 24 Tax Changes
Since April 2020, individual landlords can no longer deduct mortgage interest from rental income. Instead, they receive a 20% tax credit. This has made limited company structures more attractive for higher-rate taxpayers.
Lending Criteria in 2025
Lenders stress-test buy-to-let applications using interest coverage ratios (ICR). Most require rent to cover 125–145% of the mortgage payment at a stress rate of around 5.5%. Some specialist lenders use lower stress rates for portfolio landlords.
Limited Company Buy to Let
Purchasing through an SPV limited company allows full mortgage interest deduction and corporation tax rates (currently 25%). However, you'll need specialist BTL products, and there are set-up and accounting costs to factor in.
Yield Strategies
Focus on areas with strong rental demand relative to purchase price. HMOs and multi-lets can significantly boost yields. Consider locations with planned infrastructure improvements, university towns, and commuter belt areas around London.
