What are buy to let mortgages?

A buy to let, or buy to rent mortgage is for a landlord who wants to buy a property to rent out. 

The application is similar to a residential mortgage application but with a few differences. These differences include the amount you could borrow and how much deposit you will need.

Are buy to let mortgages interest only?

BTL mortgages are most commonly interest only mortgages, but we offer both capital and interest and interest only mortgage types for buy to let.

With an interest only mortgage, you only pay off the interest on a monthly basis throughout the term of your mortgage, however at the end of your term you are required to pay off the capital debt (the outstanding mortgage amount) in full. With a capital and interest mortgage, you pay off both the capital debt and the interest on a monthly basis.

Use our mortgage rate finder to compare rates available to you.

It depends on multiple factors including the property value, amount of deposit and rental income for the property. You could borrow up to a maximum of £3.5 million (in total across NatWest brands) with our buy to let mortgages.
