What is a buy-to-let mortgage?

A buy-to-let mortgage is a financial product designed for individuals who want to purchase property to rent it out. Unlike residential mortgages, buy-to-let mortgages are specifically tailored for investment purposes, enabling property owners to generate rental income.

Buy-to-let mortgages work by allowing individuals to borrow money to purchase a property that they intend to rent out. The key aspects include higher interest rates and typically larger deposits compared to residential mortgages.
