Mortgage

A Joint Borrower Sole Proprietor (JBSP) mortgage allows multiple people to join forces to buy a property, but only one of them owns it. This type of mortgage is particularly popular among parents helping their children step onto the property ladder. Here’s everything you need to know about JBSP mortgages, including their benefits, drawbacks, and how they work.

What is a Joint Borrower Sole Proprietor Mortgage?

A JBSP mortgage is designed to help individuals, such as first-time buyers, secure a mortgage by combining the income of up to four people. Despite multiple borrowers being jointly responsible for the repayments, only one individual—the sole proprietor—is named on the property’s title deeds and legally owns the property.

This setup makes JBSP mortgages a popular choice for parents or other family members who want to assist with buying a home without taking ownership themselves. Unlike guarantor mortgages, a JBSP considers the income of all borrowers when determining affordability, making it easier to secure a larger loan amount.

How does a JBSP Mortgage Work?

While a JBSP mortgage is similar to a standard mortgage, the key difference is ownership.
Here’s how it works:

1

Application Process

Lenders assess the income, expenses, and creditworthiness of all borrowers to determine affordability.

2

Ownership

Only the sole proprietor’s name appears on the property’s title deeds. This individual is typically required to live in the property.

3

Responsibility

All borrowers share responsibility for the mortgage repayments. If one person cannot pay, the others are liable.

4

Exit Plan

Non-proprietors can exit the mortgage when the sole proprietor’s income increases enough to take over the mortgage independently. This often happens when the initial deal period ends.

FAQ

about
JBSP
Mortgages

Most lenders allow up to four people to be named on a Joint Borrower Sole Proprietor (JBSP) mortgage. However, only one person is listed on the property title and legally owns the home. The additional borrowers are named on the mortgage but have no ownership rights.

Yes. Most lenders apply a maximum age limit, often requiring that borrowers are no older than 70 to 80 years at the end of the mortgage term. Age limits vary by lender and can depend on retirement income and affordability.

With a JBSP mortgage, all borrowers’ incomes are taken into account when assessing affordability, and all borrowers are jointly responsible for the mortgage payments. A guarantor mortgage, by contrast, relies on a guarantor’s income or assets as additional security rather than treating them as full borrowers.

In most cases, additional borrowers on a JBSP mortgage are not treated as property owners for Stamp Duty purposes. This means higher-rate Stamp Duty for second homes does not usually apply, provided the sole proprietor does not already own another property.

JBSP mortgages are commonly used by first-time buyers who need help with affordability. Parents or close family members often join the mortgage to support borrowing, without needing to be added to the property title.

Yes. Parents are frequently joint borrowers on JBSP mortgages, using their income to help support affordability. They are named on the mortgage but do not own the property unless they are also added to the title, which is not typical for JBSP arrangements.

Yes. All borrowers named on a JBSP mortgage are jointly and severally liable, meaning each borrower is legally responsible for ensuring the mortgage is repaid, even though only one person owns the property.

In some cases, yes. A JBSP mortgage can be used to remortgage an existing property, depending on lender criteria and affordability. Lenders will assess income, age, and exit strategy in the same way as for a purchase.

Often, yes. Some lenders allow joint borrowers to be removed at a later date, usually once the sole proprietor’s income is sufficient to support the mortgage on their own. This is subject to affordability checks and lender approval at the time.

No. JBSP mortgages are designed for residential properties only. Buy-to-let mortgages follow different rules and structures, and JBSP arrangements are generally not permitted for investment properties.

Yes, it can. Because joint borrowers are named on the mortgage, the debt may be taken into account when lenders assess their own future borrowing, even though they do not own the property.
