What Is a Joint Borrower Sole Proprietor (JBSP) Mortgage — and Can It Help You Buy?

Struggling to get a mortgage on your own? A Joint Borrower Sole Proprietor (JBSP) mortgage could be your solution. It lets someone else — like a parent or partner — help you get approved, without being a legal owner of the property.

It’s one of the most powerful (and underrated) tools for first-time buyers, young professionals, or anyone who needs a boost to get on the ladder.


💡 What Is a JBSP Mortgage?

A JBSP mortgage allows multiple people to be responsible for the mortgage, but only one person is named on the property title.

For example:

  • You’re buying a home
  • A parent or relative helps with the affordability
  • You own 100% of the property
  • They’re simply listed on the mortgage

This means you can borrow more than you could alone, without giving up any legal ownership.


🧠 Why Choose JBSP Over a Standard Joint Mortgage?

With a standard joint mortgage, both parties are legal owners. That’s fine if you’re buying with a partner — but risky if it’s a parent or friend.

A JBSP mortgage:
✅ Keeps your helper off the deeds (avoids second property stamp duty)
✅ Still boosts your borrowing power
✅ Can help you get on the ladder sooner
✅ Doesn’t affect your right to 100% of future equity


🔍 Who Is a JBSP Mortgage Good For?

✅ First-time buyers with low income
✅ Young professionals still early in their careers
✅ People with limited credit history
✅ Buyers supported by parents, siblings or even friends


⚠️ Things to Consider

  • All borrowers are jointly responsible for the mortgage — if one stops paying, the others must cover it
  • Lenders will assess all applicants’ credit reports and affordability
  • Not all lenders offer JBSP mortgages — you’ll likely need a broker
