What are Buy to Let mortgages?

We have temporarily restricted our lending criteria and withdrawn a number of our mortgage products, including those for buy to let. For the latest updates and essential information during the COVID-19 pandemic read our FAQs.

A Buy to Let mortgage is used when a property is to be bought and let out to tenants. The mortgage holder becomes a landlord and collects rent from the tenant. We want to support people who are entering the buy to let market for the first time and those landlords who have small portfolios of up to three properties. We don't lend to larger, commercial investors or those who hold their properties in a company or business.

It is worth bearing in mind that the regulation and legislation regarding Buy to Let property can change at any time, so anyone considering becoming a buy to let landlord should ensure they do their research first.
