Buy to Let Mortgages

A Buy to Let mortgage is designed for individuals or companies who want to purchase property as an investment rather than as their main residence. It allows landlords to generate income from tenants while benefiting from long-term capital growth. Whether you are adding to an existing portfolio or purchasing your first rental property, a tailored Buy to Let solution ensures the finance is structured in a way that supports your strategy, maximises returns and gives you the flexibility to adapt as the market or your circumstances change.

Buy to Let lenders focus primarily on the rental income the property can achieve. Instead of assessing affordability against your personal income in the same way as a residential mortgage, lenders evaluate whether the rental income is strong enough to cover the mortgage payments with an appropriate level of buffer. This is known as the rental coverage ratio, and each lender has its own calculations and stress tests depending on loan size, tax status, property type and whether the property is held personally or through a limited company.

The property itself is an important factor in Buy to Let lending. Lenders assess its suitability for the local rental market, its condition, its expected demand, and whether it fits their criteria for long-term letting. They may apply different rules for flats above commercial units, ex-local authority homes, new builds, student lets or properties with unique layouts. Experienced investors who understand tenant demand, rental trends and maintenance responsibilities often find it easier to obtain favourable terms, although there are lenders who support first-time landlords as well.

What Is a Buy to Let Mortgage?

A Buy to Let mortgage allows you to purchase or refinance property that will be rented out to tenants. Criteria, rates, and stress tests differ from standard residential mortgages, and lenders evaluate both your personal profile and the projected rental income of the property.

BTL mortgages can be taken out in personal names, through a limited company, or via an SPV, depending on your preference and tax strategy.
