Newcastle for Intermediaries relaunches Joint Mortgage Sole Proprietor range to help more customers onto the property ladder.
20 July 2026
Newcastle for Intermediaries has relaunched its Joint Mortgage Sole Proprietor (JMSP) proposition, broadening eligibility and introducing new features designed to help more customers achieve homeownership.
The refreshed range has been developed to address some of the biggest challenges facing today’s borrowers, including affordability and the difficulty of saving larger deposits, particularly among first time buyers.
Key enhancements to the JMSP proposition include:
- Expanded eligibility, with support no longer limited to close family members
- Up to 95% LTV
- Enhanced affordability through a dedicated Affordability Boost option
- Flexible underwriting to support a wider range of customer situations
- No maximum age at the end of term, including that of non-occupying borrower
The relaunch means more customers can benefit from financial support from trusted family members, friends or wider support networks without those individuals needing to be named on the property’s title deeds.
The proposition is aimed at first time buyers and home movers who have sufficient income support available but may struggle to meet affordability requirements on their own.
Francesco Di Pietro, head of intermediary mortgages at Newcastle Building Society, said:
“Affordability remains one of the biggest barriers facing aspiring homeowners today. We’ve listened carefully to brokers and customers and have redesigned our JMSP proposition to make it more accessible, flexible and relevant to the challenges borrowers face.
“Alongside expanding eligibility beyond close family members, introducing up to 95% LTV and enhancing affordability support, we’ve also made important changes to our age criteria as we understand that the non-occupying borrower will tend to be older. The maximum application age has increased to 78 and there is now no maximum age at the end of term for repayment mortgages, giving brokers greater flexibility to support a wider range of customers and family arrangements.
“We’re also pleased to introduce a long-term fixed rate Affordability Boost option, building on the success of the feature within our standard mortgage range. It provides increased borrowing potential for customers choosing longer mortgage terms, helping even more people overcome affordability barriers and take their next step onto the property ladder.”
The enhanced JMSP range is available through Newcastle for Intermediaries from 17th July 2026, with full product details and criteria available to brokers via its intermediary website.
