Verified VouchedFor review, Lincolnshire

Sometimes the only thing standing between you and the right home is the size of the mortgage a lender will offer on your income alone. A joint borrower sole proprietor mortgage solves exactly that. A parent or close family member joins the mortgage to boost your borrowing, while you remain the sole owner of the property.

Support on the mortgage, not the deeds

Because your family member is on the mortgage but not the deeds, you keep full ownership of your home and the arrangement usually avoids the extra stamp duty that a joint purchase would trigger. It is a clean, sensible way for family to help without complicating who owns what.

We know who offers it

JBSP is only available from certain lenders, and their criteria vary. We go straight to the ones who offer it, explain the responsibilities clearly to everyone involved, and structure the mortgage so it works for the whole family.

Is this you?

We help joint borrowers like…

  • First-time buyers who need an affordability boost
  • Parents wanting to help without owning a share
  • Buyers whose income alone falls just short
  • Professionals early in a well-paid career
  • Families keen to avoid extra stamp duty

Why a broker

Why joint borrowers use a mortgage adviser

Good to know

Joint Borrower Sole Proprietor (JBSP) Mortgages: your questions answered

What is a JBSP mortgage?

Joint borrower sole proprietor. A family member joins the mortgage to boost borrowing, but only you are on the property deeds, so you are the sole owner.

Does the supporting family member own part of my home?

No. They are on the mortgage but not the deeds, so they have no ownership share. This also helps avoid extra stamp duty.

Will it affect my family member's own situation?

They take on responsibility for the mortgage, so it can affect their borrowing and they should consider it carefully. We explain it fully to everyone.

Is there extra stamp duty with JBSP?

Because the supporting borrower is not an owner, the extra stamp duty that applies to second properties is usually avoided. We will confirm your position.

Which lenders offer JBSP?

Only some do, and their criteria differ. We know who they are and go straight to the ones that fit your circumstances.
