Get a Mortgage with Family Help: How JBSP Mortgages Work
Getting onto the property ladder can feel like an uphill climb, especially if your income alone doesn’t stretch far enough.
Whether you’re a first-time buyer or simply struggling to borrow enough on your own, a Joint Borrower Sole Proprietor (JBSP) mortgage could be the solution you’ve been looking for.
It’s designed to help you buy your home with the financial support of someone else, typically a parent or close family member, without giving up any ownership of the property.
At Kerr & Watson, we specialise in finding tailored mortgage and protection solutions like JBSP mortgages that work for your unique situation. If you’re considering this route, read on to learn how it works, the pros and cons, and why expert advice can make all the difference.
Thinking about a Joint Borrower Sole Proprietor mortgage?
If you’re unsure how much you could borrow or whether this is the right option for you, speaking to an adviser can make all the difference.
At Kerr & Watson, we help structure mortgages like this and can guide you through your options.
What is a JBSP Mortgage and How Does It Work?
A JBSP mortgage allows multiple people to apply for a mortgage together using their combined income, but with only one person listed as the legal owner of the property.
This means you can strengthen your mortgage application with someone else’s earnings, like your mum or dad, while keeping full ownership of the home yourself.
This type of mortgage is especially popular with first-time buyers or younger borrowers who might have a limited income or patchy credit history.
It’s also helpful for those who want to benefit from Stamp Duty exemptions that wouldn’t be available if a co-borrower also owned another property.
While all named borrowers are equally responsible for making the mortgage repayments, only your name appears on the deeds.
This legal distinction is key and has both practical and tax-related benefits.
How does a Joint Borrower Sole Proprietor mortgage work in practice?
A JBSP mortgage allows multiple people to be named on the mortgage, while only one person is named on the property deeds.
This means the additional borrower supports the application with their income, but does not own the property.
In practice:
- The main applicant is the sole legal owner of the property
- All borrowers are jointly responsible for the mortgage repayments
- The lender uses all applicants’ income to assess affordability
- The supporting borrower has no legal ownership of the property
This structure is designed to help increase borrowing power while keeping ownership simple.
Who are JBSP mortgages suitable for?
JBSP mortgages are commonly used where a buyer cannot quite borrow enough on their own but has support available from family or others.
- First-time buyers struggling with affordability
- Parents helping children onto the property ladder
- Buyers with lower current income but strong future potential
- Those looking to buy in higher-priced areas
This type of mortgage can help bridge the gap between what you can afford now and the property you want.
Who Can Be a Joint Borrower?
Usually, it’s parents who step in to support their children, but it doesn’t have to be. With some lenders, a JBSP mortgage can involve up to four people, and your co-borrowers can include:
- Parents or step-parents
- Grandparents
- Siblings
- Close friends
- Long-term partners
It’s crucial that whoever helps you is financially stable and fully understands their responsibilities. Everyone named on the mortgage is jointly liable for repayments even if they don’t live in the property or have a legal stake in it, so they are not just going on as a token gesture to get lending approved.
Why Would You Consider a JBSP Mortgage?
You might be earning a modest salary that isn’t quite enough to cover a mortgage on your own, or perhaps your credit history has a few blemishes. Either way, lenders use income multiples (typically 4.5 to 5.5 times your annual income depending on term and commitments) to decide how much you can borrow.
As an example, if you earn £20,000 a year, you might be able to borrow around £90,000–£110,000 on your own. By adding a parent earning £30,000, the combined income could significantly increase your borrowing potential, depending on the lender’s criteria.
What Are the Benefits?
There are several compelling reasons to explore a JBSP mortgage:
Boosted Borrowing Power
With multiple incomes assessed, your affordability increases. This could open the door to better mortgage deals or a wider range of properties.
Full Property Ownership
Even though someone else is helping you with repayments, the home is legally yours. You make the decisions and benefit from any increase in property value.
Stamp Duty Savings
Because your co-borrower isn’t on the deeds, you can still qualify for first-time buyer Stamp Duty relief, even if they already own another property. This could save you thousands. Understanding stamp duty for joint borrower sole proprietor mortgages
Building Your Credit
If your credit score is less than perfect, the strength of your co-borrower’s credit profile may improve your chances of approval. Over time, keeping up with mortgage repayments can help you build a stronger credit history.
Flexible Exit Strategy
When you’re financially stable and able to handle the mortgage alone, you can look into remortgaging in your sole name. This lets your co-borrower step away from the mortgage while you retain full ownership as long as you meet lender’s criteria for a mortgage on your own.
How much can you borrow with a JBSP mortgage?
One of the main benefits of a JBSP mortgage is the ability to increase how much you can borrow by combining incomes.
Lenders assess the affordability of all applicants on the mortgage, which can significantly increase borrowing potential compared to applying alone.
- Most lenders use income multiples of around 4 to 5 times combined income
- Some lenders may offer higher multiples depending on the circumstances
- All applicants’ financial commitments are taken into account
For example, a buyer earning £30,000 may be able to borrow around £135,000–£150,000 on their own. By adding a parent earning £50,000, this could increase borrowing significantly, depending on the lender’s criteria.
What deposit do you need for a JBSP mortgage?
Deposit requirements for a JBSP mortgage are generally in line with standard residential mortgages, although this can vary depending on the lender.
- Many lenders require at least a 5% to 10% deposit
- A larger deposit may improve your options and available rates
- Gifted deposits from family members are commonly accepted
As with any mortgage, the amount you can borrow and the rates available will depend on your overall financial profile.
Find out Your Options
Which lenders offer JBSP mortgages?
JBSP mortgages are available from a range of lenders, including some high street banks and specialist providers. However, criteria can vary significantly.
- Not all lenders offer JBSP mortgages
- Age limits for supporting borrowers are common
- Income types and affordability assessments differ between lenders
- Some lenders are more flexible depending on the situation
Choosing the right lender is key, which is why speaking to a mortgage adviser can help ensure you are matched with the most suitable options.
What Should You Consider?
While JBSP mortgages can offer real advantages to suitable candidates, they also come with risks and responsibilities:
Shared Liability
If you miss a payment, everyone on the mortgage suffers. A single late payment could affect your co-borrower’s credit rating, which might impact their ability to borrow in future.
Family Dynamics
Money and family don’t always mix well. Make sure you all have open, honest conversations and take legal advice so everyone understands their obligations.
Age Restrictions
Lenders often consider the age of the oldest applicant when setting mortgage terms. If your co-borrower is older, this could shorten the term and raise monthly repayments.
Limited Lender Availability
Not every lender offers JBSP mortgages, and criteria can vary widely. That’s where brokers like Kerr & Watson come in. We can help you access the right deals for your circumstances.
Stamp duty and legal considerations
One of the advantages of a JBSP mortgage is how it may be treated for stamp duty purposes.
As only the main applicant is named on the property deeds, stamp duty is typically assessed based on their circumstances.
- First-time buyers may still qualify for stamp duty relief
- Supporting borrowers are usually not considered for additional property surcharges
- Legal advice is important to ensure everything is structured correctly
Stamp duty rules can be complex and may vary depending on individual circumstances, so it’s important to seek advice where needed.
JBSP vs Joint Mortgage
It’s easy to confuse a JBSP mortgage with a joint mortgage, but the differences matter. In a joint mortgage, everyone named is both a borrower and a legal owner. That means:
- All parties appear on the title deeds
- Everyone shares ownership of the home
- Stamp Duty implications apply to all borrowers
In a JBSP mortgage, only you are listed as the legal owner, preserving your first-time buyer benefits and simplifying future ownership changes.
If your goal is to get help without giving up ownership, JBSP is usually the more flexible option.
Can You Get a JBSP Mortgage With Bad Credit?
Yes, it’s possible with some lenders. A JBSP mortgage can be especially useful if you have a low or limited credit score. By bringing in a co-borrower with a stronger credit profile, you may be able to access deals that would otherwise be unavailable.
However, be aware that you’ll still need to prove you can manage repayments. Some lenders might offer higher interest rates if risk is perceived to be greater, so it’s important to speak to an adviser who can guide you to the most suitable lenders.
At Kerr & Watson, we’ll assess your situation carefully and help you navigate the options available, even if your credit history isn’t perfect.
Can you remove a joint borrower from a JBSP mortgage?
Yes, it is possible to remove a joint borrower from a JBSP mortgage, but this is usually done by remortgaging at a later date.
The lender will need to be satisfied that the remaining borrower can afford the mortgage independently.
- This typically involves switching to a standard residential mortgage
- Affordability will be reassessed based on one income
- Many borrowers plan this from the outset as their income increases
Having a clear plan for this from the beginning can make the process much smoother.
Alternatives to JBSP Mortgages
A JBSP mortgage isn’t your only option. Depending on your goals and circumstances, other routes to homeownership might include:
- Guarantor mortgages where a parent or relative agrees to cover repayments if you can’t
- Family springboard mortgages that involve placing savings in a linked account as security
- Shared ownership schemes where you buy a portion of the home and rent the rest
- Gifted deposits from family members to boost your deposit amount
If you’re unsure what route to take, speaking to a knowledgeable mortgage adviser is key. We can help you weigh up your options and decide what’s right for you.
Using a JBSP Mortgage for Right to Buy
Some buyers explore whether a Joint Borrower Sole Proprietor Right to Buy approach could help increase affordability when purchasing a council property. This can be attractive where a family member is willing to support the mortgage but is not intended to be added to the property deeds. However, Right to Buy has strict rules around ownership and eligibility, and lenders and councils often expect the mortgage applicants to match the names shown on the Right to Buy offer paperwork. Because of this, combining a Joint Borrower Sole Proprietor structure with Right to Buy can be difficult, with only a small number of lenders willing to consider it in certain circumstances. Careful structuring and specialist advice are essential to understand whether this option is genuinely workable.
Can a JBSP Mortgage Be Used for Buy to Let?
In most cases, no. JBSP mortgages are designed for residential use and typically require that the legal owner lives in the property. A buy-to-let scenario usually calls for different mortgage types, and affordability is assessed differently.
That said, a few specialist lenders might consider JBSP structures for certain buy-to-let cases. If this is something you’re exploring, let us know at Kerr & Watson and we’ll advise on the most realistic options.
How to Apply for a JBSP Mortgage
The application process is similar to any mortgage, but with a few added steps:
- All applicants will need to provide income and employment details
- Credit backgrounds will be reviewed for all borrowers
- Legal advice will usually be needed for non-legal owners to ensure they understand their responsibilities
