Joint Borrower Sole Proprietor

Paul Collinson joins us to explain how a Joint Borrower Sole Proprietor (JBSP) mortgage can help people buy a home.

What is a JBSP mortgage and how do they work?

It’s as it sounds. JBSP stands for Joint Borrower, Sole Proprietor, which basically means that only one of the applicants needs to go on to the property deeds. The other applicants would be on the mortgage but not on the deeds.

It’s similar to a guarantor mortgage, as it helps the applicant reach an affordability level they wouldn’t otherwise have achieved. Often there’s one proprietor on the deeds for the property, and most lenders allow just one other joint borrower. A couple of lenders will allow up to three additional borrowers, however.

What criteria do you need to meet for a JBSP mortgage? Who is eligible for one of these?

Anyone’s eligible for it. You just need an income of some sort, whether it’s employed, self-employed or other income, like benefits. Not every lender accepts benefit income, though.

It would be better if your credit score was towards the top end, with not many issues on it, because only a small selection of lenders offer JBSP mortgages. So, you’ll need an income and a fairly good credit file.

Do you pay stamp duty on a JBSP mortgage?

As brokers, we’re not allowed to advise on tax, but you do get stamp duty allowances as a First Time Buyer.

And if the joint borrower already owns a property, this would not affect the First Time Buyer with a JBSP mortgage – because the joint borrower is not going on the title of the property. They’re only on the mortgage.

JBSP mortgages do benefit people in that way and make things more possible.

Can you have a sole mortgage on a joint property?

No, you can’t have it the other way around, where more than one person owns a property and are named on the title deeds, but only one goes on the mortgage. If you’re on the deeds, you have to go on the mortgage.

What’s the difference between a joint mortgage and a JBSP mortgage?

A joint mortgage is just a normal mortgage between two applicants, or sometimes up to four, where they’re all going on the title deeds. That’s a standard mortgage. But with a JBSP mortgage, one or more of the joint borrowers are not named on the deeds.

What’s the difference between a guarantor mortgage and a JBSP mortgage?

With a JBSP mortgage, all parties are jointly and severally liable for the mortgage payments. With a guarantor mortgage, that other person is only liable for those payments if you can’t make them.

With both scenarios, the other person is not legally tied to the property and or has no legal rights over it.

Can I get a JBSP mortgage with bad credit?

If any client comes to me and they have bad credit, we have to look into things a lot deeper. We look over the credit file to ascertain what issues there are, or have been in the past. We’ll then check this against the lender’s criteria.

As I mentioned, not all lenders do JBSP, so we’d have to narrow the search down. But it is possible, depending on how bad that credit is.

How does remortgaging a JBSP mortgage work?

If you’re in a fixed period, in the same way as on a standard mortgage, we’d contact you around six months before it ends. We’ll ensure you don’t go on to that lender’s standard variable rate.

We would assess your current circumstances. Maybe your income has improved and you don’t need to use the joint borrowers on the mortgage now. Maybe you only need one of them, and not the two you originally went with.

Perhaps your credit situation has changed. We’d look at the whole picture – as with any remortgage. Based on the findings of everything we would then identify the most suitable product available to you. We would recommend that one and if you’re happy, we will apply as normal.

What are the pros and cons of JBSP mortgages?

The main positives here are that it really helps people get onto the property ladder. Sometimes it’s the other way around, where instead of parents helping their children buy a home, a son or daughter is helping their parents.

They might be buying a home a bit later in life, or trying to remortgage. Maybe they have split up from their partner and their income isn’t enough to remortgage their current property on their own, so they need to add their son or daughter to boost the total income.

The disadvantage to this type of scheme is that if the person helping you needs to buy or remortgage their own property, the JBSP mortgage is still seen as a commitment. It would hugely affect affordability on their own property – ultimately it’s another mortgage on their credit file.

We could obviously discuss all these things in more detail with you. You do have to be very careful and get advice from a broker. So just contact us here and we can guide you through.

What else do we need to know about a JBSP mortgage?

Every situation is different. It might be a young person buying a home or someone’s parents. You could be helped by a friend – sometimes lenders are okay with that. But overall it’s the same as a normal property purchase.

You just contact us initially and find out what your maximum borrowing amount is. You’d then know what value of property to look at. Then, when you find something that you like, you put an offer in, it’s accepted and we carry on with the process. We’re here to hold your hand all the way to completion – the day you move in.

YOU MAY HAVE TO PAY AN EARLY REPAYMENT CHARGE TO YOUR EXISTING LENDER IF YOU REMORTGAGE.

THINK CAREFULLY BEFORE SECURING OTHER DEBTS AGAINST YOUR PROPERTY. YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON YOUR MORTGAGE.

HM Revenue and Customs practice and the laws relating to taxation are complex and subject to individual circumstances and changes which cannot be foreseen.

Joint Borrower Sole Proprietor (Part 2)

Paul Collinson answers more of your questions on Joint Borrower Sole Proprietor (JBSP) mortgages. Episode two of two on this topic.

Is there a Joint Borrower Sole Proprietor mortgage age limit?

Yes, there are options up to the age of 80 at the end of the mortgage term. This does depend on lenders’ criteria, such as the income at that age and occupation.

Some lenders are strict about people working to the age of 80 if they’re in a certain job role. We can look at those options for you, so just give us a shout.

What documentation is required for both the joint borrower and the sole proprietor in a JBSP application?

It’s much the same as a standard application, but there are obviously more of them as we need documents for everyone. You need your latest three months’ pay slips if you’re employed, and if you’re self-employed, we need the latest two years’ tax calculations and tax year overviews.

In both cases, we will need the latest three months’ bank statements and either a licence or passport for ID purposes.

Are there restrictions on the types of properties that can be purchased with a JBSP mortgage?

No, there aren’t. As long as the property fits a lender’s standard property criteria, it would be fine with a JBSP mortgage as well.

Can the joint borrower be added after the mortgage has already been taken out?

Yes, they can be. It’s normally at the point of a remortgage at the end of a fixed period, if needed.

For example, if someone’s income has dropped or their situation isn’t as good as when they first did the mortgage, a parent or even friends can step up to be a joint borrower. We can use their income to keep the affordability where it needs to be.

Can I get a JBSP mortgage with my parents? Can I get a JBSP mortgage with my children?

With parents is the normal way of doing things. The JBSP mortgage is mainly used for parents to help their children buy a home.

But I have also seen it the other way around, where children are helping their parents. In both cases, solicitors want to see that the joint borrower has sought independent legal advice. But you don’t need to do that until the application is in – and some lenders have different forms to others.

Can I get a JBSP mortgage with my siblings or friends?

Yes, indeed. I’ve got lenders that allow that, both with siblings and friends. It’s not all lenders, but a couple of them do allow that.

How does having multiple joint borrowers affect a JBSP mortgage application? Are there limits on the number of joint borrowers in a JBSP mortgage?

There are just extra documents required because there are more people. Fewer lenders will do this – it’s not the whole of the market.

The maximum number of joint borrowers is four, which means potentially there can be three joint borrowers plus a sole proprietor.

Are there additional fees or costs associated with taking out a JBSP mortgage?

No, not on the actual mortgage. But as I mentioned, you do have to get independent legal advice, which will have a cost. You’d need to get a quotation from a solicitor.

I did have someone recently who had a few quotes and it was anywhere between £150 and £650. It’s always worth checking the costs on that.

What else do we need to know about Joint Borrower Sole Proprietor mortgages?

I think we’ve covered a lot there. If anybody has any questions that pop into their head at any time, just give us a call. We’re available most of the time and will be pleased to help you.

Joint Borrower Sole Proprietor (Part 3)

Paul Collinson answers more questions on a Joint Borrower Sole Proprietor mortgage. Part three of the series, recorded in May 2025.

Podcast approved by The Openwork Partnership on 07/05/2025.

Can I use a Joint Borrower Sole Proprietor JBSP mortgage to buy a second home or holiday home?

Yes, you can, but there’s a very small market of lenders that would do this.

Does the joint borrower have to live in a different property?

There are lenders that are okay with them living in the same property – although not many. But it is possible for the joint borrower to live in the property with the sole proprietor.

Can I switch from a standard mortgage to a JBSP mortgage?

Yes – you can remortgage and change that. It would probably be where circumstances have changed and you wouldn’t fit affordability this time around. You may need to add somebody to help you out. We would help you remortgage and look at those options.

How do interest rates compare for JBSP mortgages?

A couple of lenders do still offer rates at the top of the table, near the main high street lenders. Others that do JBSP are subprime lenders or non-standard lenders.

With the lenders that source near the top, there wouldn’t be a lot of difference if other parts of the criteria fit with the client.

Is it possible to use a JBSP mortgage for Buy to Let properties?

Yes, but it’s very rare. A minority of lenders will do it, but not the main high street lenders. A couple out there will do that for you.

What happens if the joint borrower passes away or can’t pay the mortgage?

If the joint borrower passes away, the responsibility is on the surviving sole proprietor. The situation could be slightly awkward for that surviving person – they might not be able to afford the mortgage independently, but now it’s purely their responsibility.

With JBSP, there can be more than two people – it could be three or four. Obviously, in this situation, taking out a life insurance policy to pay the mortgage off in the event of a death would help.

If the joint borrower isn’t there to pay the mortgage, it would just make all the others liable to pay instead.

Can I get a JBSP mortgage if one borrower has an existing mortgage?

Yes you can, but there are risks, so you’d need to come to us first to discuss the implications. For example, if a joint borrower helping you has another property, that mortgage payment would need to be factored into their affordability for the new one.

With an existing property, once it’s time to remortgage, this new JBSP mortgage payment would count towards affordability for that, as well. We need to explore the details and advise in the right way as each person’s circumstances are different. You can do it, we would just need to discuss some things first.

Are there any special considerations for older joint borrowers in a JBSP mortgage?

Not really, but there’s a certain maximum age that lenders will go to – normally 75 or 80. Obviously, if older parents are helping their children out, there might be a certain limit to the mortgage term. Or, you might consider a non-standard lender, but it’s very rare to go past 80. It’s normally 75 or 80.

How can a mortgage broker help with JBSP mortgages? Have you got anything else to add?

As always, you can contact us here at Brick2Brick and we’ll guide you through from start to finish. At the beginning, we’ll confirm what you can borrow, and we’ll support you all the way to completion when you move in. Just get in touch and we’ll guide you through the process.
