A Joint Borrower Sole Proprietor (JBSP) mortgage is a type of family-assist property loan where multiple people are legally responsible for making the mortgage payments, but only one person actually owns the property. It is specifically designed to help buyers (often first-time buyers) who cannot borrow enough money on their own due to a lower salary.

How It Works

  • On the Mortgage (The Borrowers): Typically, a child and one or both parents apply together. All of their incomes are combined by the lender to boost the total amount of money they can borrow. Everyone on the mortgage is 100% legally responsible for making sure the monthly payments are made.
  • On the Property Deeds (The Owner): Only the child’s name is listed on the property deeds (the Land Registry). The parents have no legal ownership or claim over the house.
