Joint Borrower Sole Proprietor (JBSP) Mortgages
Getting onto the property ladder can feel challenging, especially if affordability is holding you back.
A Joint Borrower Sole Proprietor (JBSP) mortgage could be the solution - and at Birmingham Mortgage Hub, we specialise in helping clients across Birmingham and the UK secure this type of mortgage.
A JBSP mortgage allows other people, typically family members, to support your mortgage application by contributing their income to the affordability assessment - without being named on the property deeds. This means you can borrow more, improve your chances of mortgage approval, and still keep the ownership of the property in your name only.
Our team of mortgage advisers will explain how JBSP mortgages work, guide you through the pros and cons, and match you with the most suitable lenders from our panel of over 90 providers.
How Does a JBSP Mortgage Work?
A JBSP mortgage is a home loan where multiple people are named on the mortgage application and share responsibility for repayments, but only the main borrower is named on the property deeds.
This arrangement is popular for:
- Parents helping children buy their first home
- Avoiding additional stamp duty charges for family members who already own property
Benefits:
- Increase borrowing potential by using a family member’s income
- Keep property ownership in your name alone
- Avoid extra stamp duty for supporting borrowers
- Get support without requiring a formal gift or guarantor arrangement
Considerations:
- All borrowers are jointly responsible for mortgage payments
- Lenders assess income and commitments of all applicants
- Not all lenders offer JBSP mortgages — specialist advice is essential

Alternatives to JBSP Mortgages

- Wait and save – Build a larger deposit for better rates
- Joint mortgage – Share ownership and responsibility
- Shared ownership – Buy a percentage of a property and pay rent on the rest
- Gifted deposit – Boost borrowing without joint income
- Guarantor mortgage – A family member guarantees repayments
We’ll help you explore all options and decide what’s best for your situation.
