Buy-to-Let (BTL)

A mortgage on a property you intend to rent out.

Full definition

A mortgage product for properties bought to rent to tenants, rather than to live in yourself. Assessed primarily on rental income coverage (ICR) rather than personal income. Typically requires a 25% deposit. Most BTL mortgages are not regulated by the FCA. See our full Buy-to-Let guide.
