Did you know… you could get a bigger mortgage WITHOUT buying with someone else?
It’s called a Joint Borrower, Sole Proprietor (JBSP) mortgage 👇
This is where:
👉 A family member (usually parents) helps you boost affordability
👉 BUT… they are NOT on the property deeds
👉 Meaning you own 100% of the property
Why do people use this?
✔️ First-time buyers struggling with affordability
✔️ Trying to borrow more based on income
✔️ Wanting help from family without giving up ownership
✔️ Avoiding additional stamp duty for the helper
Things to be aware of:
– The other person is still liable for the mortgage
– Their income and commitments are assessed
– It can impact their future borrowing
– Not all lenders offer this
Simple example:
You earn £30k
On your own, you might borrow ~£135k
Add a parent earning £40k…
Now your borrowing power could increase significantly
This can be the difference between “Still renting” vs “Getting on the ladder”
If you're stuck thinking “I can’t afford to buy yet”…
You might be closer than you think.
