A NatWest Family-Backed mortgage, sometimes known as a ‘joint borrower sole proprietor’ (JBSP) mortgage, can help buyers get moving sooner or borrow more. It lets you add a second person to your mortgage but without them owning the property.
Adding a second person to your mortgage as a 'non-owner', can help you borrow more than you would otherwise have been able to borrow, which means you could move home sooner than you thought. And, the non-owner could be a family member or friend. Exclusions and criteria apply.
We provide you with the information to enable you to make an informed decision about a mortgage product that is right for you. If you don't feel confident applying for a mortgage by yourself, you can arrange an appointment with one of our mortgage advisers, who could advise you on a product suitable for your needs. By making your own choice you do not benefit from the protection of us making a recommendation suitable for your needs and you alone are responsible for the choice that you make. This means that you would not be eligible for compensation if the product you choose turns out to be inappropriate for your needs.
