Joint Borrower Sole Proprietor

A great solution for young borrowers and parents who want help to increase their borrowing capacity.

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

Helping family members support each other with affordability

What is a Joint Borrower Sole Proprietor arrangement?

A Joint Borrower Sole Proprietor (JBSP) mortgage allows family members to help a borrower secure a mortgage by adding their income to the affordability assessment, without being named on the property deeds. This means the borrower owns the home outright, while the joint borrowers share responsibility for the mortgage repayments.

Frequently asked questions View our JBSP mortgages

What are the benefits?

  • You can increase your mortgage affordability and secure a larger loan than you could on your own
  • Even if you're an older borrower, we offer mortgage terms up to the age of 95, taking various retirement income streams into account to support long-term affordability
  • You may be able to borrow up to 90% of the property's value through the mortgage, depending on the Loan to Value (LTV) of your mortgage.

What is 'Loan to Value'?

This is the size of your mortgage loan divided by the value of your property. For example, if you’re buying a £100,000 property with a £10,000 (10%) deposit, you’ll need a 90% LTV mortgage.

You can see the maximum loan amounts we can offer, depending on the loan to value and the repayment method, for JBSP arrangements below:

With our Joint Borrower Sole Proprietor (JBSP) mortgage, the purchaser owns the property outright, and only their name is on the deeds. However, family members can join as co-borrowers, and their income and financial commitments will be included in the affordability assessment.

JBSP is ideal for those moving home, remortgaging, or raising funds for specific purposes like buying out another party to the mortgage or funding essential home repairs.

Contact our New Business Team on 03330 140140 or by use the Call Me Back form. They’ll go over some basic information with you including how much you would like to borrow and what for. They’ll need to know about your income and outgoings to make sure you can afford the mortgage and they’ll check that the mortgage meets our lending criteria.

Our standard affordability test is used. This includes the committed expenditure of all households, such as council taxes, loans, credit cards, etc. Additionally, mortgage costs and rent will be taken into account for all borrowers, including non-occupying borrowers.

You can have up to four people named on a JBSP mortgage:

  • 1 or 2 people who will own and live in the property
  • Up to 2 family members who support the application for affordability to boost the amount you can borrow, but will not own the property

It’s important to remember that everyone named on the mortgage is jointly responsible for making the mortgage repayments, but only those named on the property deeds have legal ownership of the property. 

If the relationship between borrowers breaks down, it may be challenging to remove joint borrowers from the mortgage. Joint borrowers have no legal claim to the property or any increase in its value over time. However, if the sole proprietor stops making payments, the joint borrowers are responsible for the full mortgage amount, and missed or late payments could negatively affect their credit scores. Any payment issues will appear on all parties' credit reports.

We can also reverse the traditional JBSP mortgage arrangement, so that adult children can help to support their parents’ mortgage application.

This can help parents borrow more or stay in their home for longer. If you want to find out more about how you can support your close family members with a Joint Borrower Sole Proprietor mortgage, contact our free Mortgage Advice Service.

If you're a first-time buyer purchasing a property you may not have to pay stamp duty, depending on the property’s value. Please check gov.uk for the current thresholds. The joint borrowers won’t be liable for stamp duty since they won’t own any part of the property - the purchaser remains the sole proprietor.

The key difference is ownership:

  • With a JBSP mortgage, only the person (or people) living in the property owns it. Supporting family members join the mortgage to help improve affordability but are not legal owners
  • With a joint mortgage, all borrowers are legal owners of the property

Both options can increase borrowing power, supporting first time buyers or lower-income individuals to get on the property ladder sooner. In both cases, everyone named on the mortgage is equally responsible for mortgage repayments.

JBSP mortgages are a great way of supporting family members with their mortgage application, particularly if you have a better credit history or larger income.

By adding your name to the mortgage, this can increase the value of household income used in the application and improve the chances of the mortgage application being approved. JBSP mortgages can also be reversed, where adult children support their parents to get a mortgage or remain in their current home.

We offer mortgage terms up to the age of 95 for capital and interest repayment mortgages.
