What is a NatWest Family-Backed mortgage?

A NatWest Family-Backed mortgage, sometimes known as a ‘joint borrower sole proprietor’ (JBSP) mortgage, can help buyers get onto the property ladder sooner or borrow more. It lets your customer add a second person to the mortgage but without them owning the property.

Adding a second person to the mortgage as a 'non-owner', can help your customers borrow more than they would otherwise have been able to borrow, which means they could buy their own home sooner than they thought. And, the non-owner could be a family member or friend.

Criteria

  • We require a minimum income of £20,000 gross per annum for the main applicant owner/occupier. This can be made up of all acceptable income types.
  • Standard residential mortgage policy rules will apply to all applicants, which includes our eligibility criteria of minimum age of 18 to maximum age of 75.
  • The non-owning borrower is not limited to family, it can be a friend.
  • This is not available with mortgage schemes such as Right to Buy and Shared Equity.
  • This is only applicable for Residential Purchase Products.
  • Maximum of 2 applicants: the owner and the non owner.
  • A fact sheet must be provided to the non-owning borrower at the point of application.
  • The non-owning borrower must seek independent legal advice before completion. An Independent Legal Advice Certificate will be sent to the non-owning borrower with the mortgage offer, seeking confirmation legal advice has been obtained. You must then upload this to the Broker Portal.

Important steps for non-owners
