'You can consider up to four incomes to boost affordability? Wow! I didn't know you did that!'

1 May 2025

Our Joint Borrower Sole Proprietor mortgages can be used by first time buyers or second steppers needing help with affordability. As we can lend up to age 95, they can also support clients into retirement or help parents stay in the family home for longer.

Great news! We’ve increased the max LTV for our Joint Borrower Sole Proprietor (JBSP) products up to 90% (based on a max loan size of £500,000), to support those with smaller deposits. 

We’ve also increased the max loan size up to £1,000,000, helping those who need to borrow more.  

Benefits of JBSP 

  • Up to four incomes can be used for affordability – one or two borrowers (who will own and occupy the property) can be supported by up to two other family members
  • Clients can boost their affordability and secure a larger loan than they’d be able to on their own
  • Supporting family members will not be liable for stamp duty on a second home – they will be listed on the mortgage but will not own the property.

Who can support a JBSP arrangement? 

  • For Owner Occupier arrangements, family members who can provide support include parents, grandparents, siblings, aunts and uncles.

Reverse JBSP 

  • All of our JBSP arrangements can be reversed, with adult children supporting their parents with affordability allowing them to stay in the family home for longer.

Owner Occupier 

  • Repayment mortgages, up to a maximum age of 95 at the end of term
  • Interest-Only up to a maximum age of 89 when the loan commences
  • Up to 90% LTV
  • If any of the loan is on an Interest-Only basis, the mortgage must finish before either the expected retirement age of the eldest supporting (non-occupying) borrower or by age 70, whichever is sooner.

Buy to Let 

  • If your client needs a Buy to Let mortgage, they can apply for a JBSP arrangement on our standard product range:
    – Maximum age of 89 when the loan commences
    – Up to 75% LTV.
  • If any of the loan is on an Interest-Only basis, the mortgage must finish before either the expected retirement age of the eldest supporting (non-occupying) borrower or by age 70, whichever is sooner.
