📣 Calling all First-Time Buyers & Remortgage Clients! 📣
There’s a mortgage product that’s well worth knowing about if you need a little extra support to get onto the property ladder. 🏡🪜
❓What is a Joint Borrower Sole Proprietor (JBSP) Mortgage?
A JBSP mortgage is designed to help people who may not quite meet affordability requirements on their own.
It allows a close family member to join the mortgage application, helping to increase the amount you may be able to borrow.
You’ll still be the homeowner and responsible for making the monthly mortgage payments. The family member is there to provide additional financial support if needed, giving lenders extra reassurance.
For many buyers, it’s a great stepping stone onto the property ladder. Once you’re able to afford the mortgage independently—perhaps following a salary increase or once other financial commitments have reduced—you may be able to remove the supporting family member from the mortgage.
💡 It’s worth noting that the mortgage term is usually based on the age of the oldest applicant.
❓What does this mean in practice?
🟢 You own the property. Only your name appears on the title deeds, so all legal ownership and decisions remain with you.
🟢 Your family member helps with affordability. Their income is considered as part of the application, which could affect how much they’re able to borrow themselves in the future.
🟢 No Stamp Duty liability for the supporting family member, as they are not a legal owner of the property.
🟢 Independent legal advice is required for everyone involved, ensuring each person fully understands their responsibilities.
🟢 Different from a guarantor mortgage. Your family member isn’t putting their own home or savings up as security—they’re simply agreeing to support the mortgage if you’re unable to make the repayments.
