Joint Borrower Sole Proprietor (JBSP)
Parents on the mortgage, child on the title.
Full definition
A mortgage structure where multiple borrowers are jointly liable for the loan but only one is named on the property title. Common use: parents help a child buy by adding their income to the affordability calculation, without the parents becoming property owners (which would trigger the SDLT second-property surcharge and lose the child's FTB SDLT relief).
