Metro Bank launches greater than 95% LTV JBSP mortgage

ended 08. July 2026

Metro Bank has launched a new Joint Borrower, Sole Proprietor mortgage product, created to help first time buyers on to the property ladder, with the support of an immediate family member, as well as those already on the property ladder. Full details >> here <<.

The mortgage allows customers to borrow over 95% and up to 100% of the value of the property, providing they have an immediate family member such as a parent to act as the Joint Borrower in the event of a missed payment or change in financial circumstances. Lending will be subject to Metro Bank’s affordability checks and borrowers will need to meet enhanced eligibility requirements.

The application process through both the broker and direct channels will see borrowers receive specialist mortgage advice before applying for the product.  Both the borrower and the joint borrower will be deemed liable for the repayments, but the borrower will retain all rights to the property with the joint borrower stepping in as a safety net to cover the cost of repayments if required. 

Do you do many JBSP mortgages? Is lending up to 100% for this kind of mortgage a good idea (at least for the parent)? Any other thoughts, from whatever angle, send them across.

Greater than 95% LTV Joint Borrower Sole Proprietor mortgages could be a real lifeline for some first-time buyers struggling to save a deposit, particularly where affordability is strong but family support is available.
Just because someone can borrow 100% doesn’t necessarily mean they should. Buyers still need to budget for the ongoing costs of homeownership and ensure they have enough financial breathing room once they move in.
It’s also vital that parents understand they aren’t simply acting as a guarantor. They are jointly liable for the mortgage if the borrower can’t make the repayments, so it’s important they fully understand the commitment before proceeding.
These products can work well in the right circumstances, but only where both parties fully understand the responsibilities involved and have taken appropriate mortgage advice.

JBSP mortgages can be a useful way of helping first-time buyers onto the ladder, and we do see interest in them, especially where parents want to support without being added to the property title.

But 100% lending makes the risk much sharper. The parent is not just offering moral support, they are jointly liable for the mortgage. If payments are missed, it can affect their credit file, future borrowing and retirement plans.

It is good to see innovation, but this needs very careful advice. The big question is not just whether the buyer can get the keys, but what happens if rates rise, income falls, or the parent later needs borrowing of their own.

Asking for financial support from Mum and Dad can come in many guises; adding their spare income to your mortgage application is becoming a popular option, and borrowing up to 100% of the purchase price will appeal to those with limited savings or struggling to save a deposit whilst renting. Such schemes do need careful consideration, as parents will become liable for the mortgage if the kids don't pay, but at least the ownership will not mean any extra stamp duty is payable. Good from Metro Bank; another useful option in the market.

Joint Borrower, Sole Proprietor mortgages can be an excellent solution where affordability is the barrier rather than the deposit. One of their biggest strengths is that parents can help children onto the property ladder without giving up ownership of the home or becoming a legal owner themselves.

The 100% lending will grab the headlines, but that shouldn't distract from the real question: is it the right solution for that family? Like any mortgage, borrowing more is only sensible if the repayments remain comfortable should circumstances change.

This is good news, because for most of the people we speak to the problem was never whether they can afford a mortgage, it's that they can't save a deposit while handing over most of their income in rent every month. Plenty of renters could comfortably cover a monthly payment tomorrow, they're just trapped paying someone else's mortgage instead of their own, and a product like this finally gives that group a way in.

What's smart about it is that it works off affordability rather than a big cash gift. We've had years of the Bank of Mum and Dad, but a parent in their early 50s isn't always sitting on a pile of spare cash, they've often still got their own mortgage, they're facing smaller pensions than their parents had, and they may inherit less because people are living longer. This lets that parent support their child with their income and stability rather than a deposit they simply don't have, which is exactly the kind of help a lot of families actually need right now.

Metro Bank’s new 100% LTV Joint Borrower, Sole Proprietor (JBSP) mortgage sounds like a first-time buyer’s dream. Zero deposit, backed by parental income, and no stamp duty traps. It's great innovation, but let’s look at the reality. In 10+ years as a broker, I can count the JBSPs I’ve written on one hand.
Metro goes up to age 80, but terms are tied to the oldest applicant. If a parent is 55, a compressed 25-year term sky-rockets monthly payments, crushing the child's affordability. Factoring in a parent’s current mortgage, lifestyle, and commitments against a shorter term means the math rarely works.
It’s brilliant PR for Metro Bank, and it will fit a very specific, high-earning niche where a parent is young and wealthy. But for the average first-time buyer, the age and term bottleneck will keep this product firmly on the shelf for most brokers.

We're seeing steady interest in Joint Borrower Sole Proprietor (JBSP) mortgages as families look for ways to help first-time buyers overcome affordability challenges. These types of mortgages have replaced the traditional guarantor mortgages of previous years, and offer family members the opportunity to support first time buyers get onto the property ladder.

We have seen a significant increase in demand for JBSP mortgages as property prices continue to rise and affordability has become stretched. A 100% JBSP option will undoubtedly open the door for some buyers who would otherwise be locked out of the market, but it also increases the importance of robust affordability assessments and clear advice for everyone involved. Parents or family members acting as joint borrowers are taking on a significant financial commitment, so it's essential they fully understand the risks as well as the opportunities.
