Buy to Let Mortgage Information

Whether your client is a first time landlord, or has existing Buy to Let experience, we offer a range of fixed rate Buy to Let products up to 75% LTV for both purchases and remortgages.

Your clients can choose between an ICR mortgage, that uses their rental income to calculate affordability, or Top Slicing, which can boost the amount they can borrow, by using a combination of rental income and their personal income.

You can create an AIP for either with a soft footprint, only leaving a hard footprint once your client’s ready to proceed to a full application.

Use our Buy to Let affordability calculator to see how much they could borrow.
