How to use someone else’s income to get a mortgage 👀🏡
Not everyone can borrow enough on their own.
That’s where a Joint Borrower Sole Proprietor (JBSP) mortgage can help.
In simple terms, someone joins the mortgage with you and their income is included in the affordability assessment.
This can potentially increase how much you’re able to borrow.
The key thing people don’t realise?
🏡 You own the property
📝 The other person is on the mortgage but not the title deeds
Who can help?
Often parents, grandparents or siblings, although this can vary depending on the lender.
A JBSP mortgage can be particularly useful for buyers who have a good income but need a little extra affordability support to get onto the property ladder.
It’s important to remember that the joint borrower is still legally responsible for the mortgage if payments aren’t maintained, so it’s a significant commitment for everyone involved.
There are also additional caveats and considerations with this type of mortgage, which is why it’s important to understand the full implications before proceeding.
Independent legal advice should always be considered, as neither I nor the lender can advise whether this is the right route for your personal circumstances.
For some buyers, this can be the difference between buying now and waiting several more years 👀

Your home may be repossessed if you do not keep up repayments on your mortgage.
