Joint Borrower, Sole Proprietor Mortgages: A Family-Friendly Solution for Home Ownership

In today’s challenging housing market, where property prices soar and wages struggle to keep pace, achieving home ownership on a single income can feel daunting. For many young buyers, saving a substantial deposit and meeting affordability criteria is a huge hurdle, while older homeowners often seek flexible solutions to access equity in later years. 

A Joint Borrower, Sole Proprietor (JBSP) mortgage offers a family-focused alternative that supports both ends of the spectrum. Whether helping a first-time buyer secure their dream home or enabling parents over 55 to access equity, JBSP mortgages allow families to join financial forces—without joint ownership—providing a practical path to property.

What Is a Joint Borrower, Sole Proprietor (JBSP) Mortgage?

A Joint Borrower, Sole Proprietor mortgage is a financial solution that allows up to four individuals to contribute their income to a mortgage application, even though only one person will legally own the property. 

This mortgage type is designed to help family members support each other, particularly when someone’s income alone doesn’t meet the lender’s affordability requirements. In contrast to guarantor mortgages, where family members take responsibility for repayments only if the primary borrower defaults, JBSP mortgages enable co-borrowers to contribute directly to monthly repayments. 

This approach increases borrowing capacity and helps families support one another without requiring shared ownership.

How JBSP Mortgages Work?

Joint Borrower, Sole Proprietor mortgages combine the incomes of multiple applicants to enhance borrowing potential, while ownership of the property remains solely with the primary borrower. Here’s a breakdown of how this structure works:

  • Primary Borrower: The person who will own and live in the property, appearing as the sole owner on the title deeds.
  • Additional Borrowers: Family members, such as parents or close relatives, who add their income to boost borrowing power without appearing on the property title.
  • Single Title Ownership: Since only the primary borrower is on the title deed, additional applicants are not liable for additional stamp duty on second properties.

JBSP mortgages are ideal for various scenarios: younger buyers needing additional financial support, or parents who may benefit from equity release. With this mortgage, families can combine resources without the complications of co-ownership, as lenders typically allow up to four applicants to be on the mortgage application.

When a JBSP Mortgage Can Help?

Supporting First-Time Buyers

For many young people, saving for a home deposit while demonstrating sufficient income to meet mortgage criteria can be a challenge, especially with the rise in living costs and property prices. A JBSP mortgage offers a solution for families wanting to help:

Helping Children onto the Property Ladder
With a JBSP mortgage, parents or relatives can add their income to a young buyer’s mortgage application, allowing them to secure a home sooner and potentially afford a larger property than they would independently.

Assisting Parents with Equity Release

Older homeowners may sometimes need access to the value locked in their property, whether to cover medical expenses, supplement retirement income, or support other financial needs. In cases where traditional equity release options aren’t suitable, a JBSP mortgage can bridge the gap:

Helping Older Parents Over 55
By adding family members’ income to a mortgage application, parents over 55 can gain access to their home’s equity without relinquishing ownership. This flexibility makes JBSP a versatile alternative for older homeowners needing financial support.

An Alternative to Guarantor Mortgages

JBSP mortgages also serve as a more flexible option compared to traditional guarantor mortgages, offering several advantages:

  • Direct Contribution to Repayments
    Unlike a guarantor mortgage, where the guarantor only steps in if repayments are missed, JBSP mortgages enable family members to make regular contributions, reducing the financial strain on the primary borrower.
  • Avoiding Additional Stamp Duty
    Since only the primary borrower owns the property, co-borrowers avoid the extra stamp duty that usually applies to non-resident family members listed on property deeds. This makes JBSP mortgages a cost-effective way for families to lend a helping hand.

Advantages of a JBSP Mortgage

Joint Borrower, Sole Proprietor mortgages come with several key advantages, making them a flexible choice for families supporting each other financially:

Increased Borrowing Potential:
By combining the incomes of multiple applicants, a JBSP mortgage raises the borrowing limit, making it possible to purchase a higher-value property that might otherwise be out of reach.

Avoids Additional Stamp Duty:
As only the primary borrower is listed on the deeds, the additional applicants avoid paying stamp duty charges that typically apply to second properties for non-resident borrowers.

Support for Younger Buyers or Older Parents:
Whether helping a young buyer onto the property ladder or supporting parents with an equity release solution, JBSP mortgages provide a structured and flexible approach to bridging financial gaps.

Direct Contribution Without Ownership:
Unlike guarantor mortgages, which only hold the guarantor responsible in case of missed payments, JBSP mortgages allow family members to contribute directly to repayments without needing ownership.

Option to Remove Co-Borrowers Later:
Once the primary borrower’s financial situation improves, co-borrowers can be removed, providing a flexible solution for families who only need temporary support.

How to Apply for a JBSP Mortgage?

Applying for a Joint Borrower, Sole Proprietor mortgage is straightforward but requires a few important considerations to meet eligibility criteria. Here’s what to keep in mind:

  1. Identify Suitable Lenders
    Not all lenders offer JBSP mortgages, so finding a lender who specialises in family-oriented mortgage solutions is crucial. A mortgage broker like Mortgage Knight can help identify the best lender and guide you through the application process.
  2. Prepare Financial Documentation
    Each applicant needs to provide financial documentation, including proof of income, recent bank statements, and a credit report. Since all applicants’ incomes are considered, the lender will assess each person’s credit profile and financial stability.
  3. Understand Co-Borrower Obligations With JBSP mortgages, all co-borrowers share responsibility for repayments. Any missed payment will affect all applicants’ credit records, so it’s essential to discuss repayment expectations and responsibilities clearly from the outset.

Comparing JBSP Mortgages to Other Family Mortgage Options

It’s worth exploring how JBSP mortgages compare to other family mortgage options to ensure they’re the best choice for your circumstances:

Guarantor Mortgages: While guarantor mortgages allow a family member to support a loved one’s mortgage by guaranteeing repayments, they don’t permit direct income contribution. In JBSP mortgages, family members can actively contribute to monthly repayments, making them a practical option for those looking to share the financial load.

Family Offset Mortgages: Some lenders offer family offset mortgages, where family savings are offset against the mortgage balance to reduce interest. While effective for certain families, these options don’t boost borrowing capacity in the same way JBSP mortgages do. For families with income support rather than large savings, JBSP can be the more fitting choice.

Key Considerations and Limitations of JBSP Mortgages

While JBSP mortgages provide notable advantages, there are a few limitations and considerations for potential applicants to be aware of:

  • Term Restrictions for Older Applicants:
    Lenders may impose restrictions on mortgage terms for co-borrowers over 55, as approaching retirement age can impact the loan length and amount. Families may want to consider future affordability if retirement income changes for older co-borrowers.
  • Credit Score Requirements for All Applicants:
    Each applicant’s credit profile will be scrutinised by the lender. If one co-borrower has a low credit score, it can affect the application outcome. Ensuring all applicants have a solid credit history is essential for JBSP mortgage approval.
  • Repayment Responsibility for All Applicants:
    Each applicant is jointly responsible for repayments, which means any missed payment will impact the credit record of all borrowers involved. It’s vital to have a clear repayment plan to avoid financial strain and protect each applicant’s credit.
  • Complexities in Removing Co-Borrowers:
    Although it’s possible to remove co-borrowers, the process may involve refinancing the mortgage. This can incur extra costs and requires the primary borrower to meet affordability checks independently.
