How We Secured A £1.39m Joint Borrower Sole Proprietor Mortgage For Clients With Complex Circumstances

May 25th, 2023

Rated 4.97 out of 5 from 2,400+ reviews

The Proposition

When two clients approached Private Finance, their situation was anything but straightforward.

One was a partner at a property consultancy with an existing portfolio of three properties — one residential and two investment — who was planning to convert his residential property into a let-to-buy. The other was a first-time buyer. Together, they needed to raise £1.39m against a residential property valued at £1.85m, and they had a very specific mortgage structure in mind.

The solution they were seeking was a Joint Borrower Sole Proprietor (JBSP) mortgage. This type of mortgage allows two or more people to be named on the mortgage for affordability purposes, while the legal ownership of the property is held in the name of just one individual — in this case, the first-time buyer. It is a structure increasingly used by family members or partners looking to support a purchase without taking on a share of the property itself.

The Challenges

This case presented several layers of complexity that placed it well outside the scope of mainstream mortgage lending.

First, our clients required an interest-only mortgage at a loan-to-value (LTV) of 75%. Interest-only lending at this level is already a niche requirement, but combined with a loan size exceeding £1m and the added complexity of a JBSP structure, the number of willing lenders narrowed considerably. Very few providers in the market are equipped — or willing — to accommodate all three of these criteria simultaneously.

Second, one applicant held mortgaged properties in the background, including investment properties that would need to be taken into account during the lender’s affordability and risk assessment. Not all lenders will consider background mortgage commitments of this nature, particularly at high loan values, which further reduced the pool of suitable options.

Whether your mortgage requirements are straightforward or highly complex, our brokers have the experience and market access to find the right solution. Speak to us today to explore your options.

The Solution

With whole-of-market access and established relationships with specialist lenders and private banks, Private Finance is uniquely positioned to navigate even the most challenging mortgage scenarios.

Our broker conducted a thorough review of the market, identifying lenders with a genuine appetite for this type of high-value, specialist lending. After careful research and negotiation, we secured a competitive interest-only JBSP mortgage at a rate of 2.29%, covering the full required loan amount of £1.38m. The mortgage met every one of our clients’ requirements — the right structure, the right LTV, and a rate that represented strong value given the complexity of the case.

This outcome demonstrates the significant advantage of working with a specialist mortgage broker rather than approaching lenders directly. For clients with complex income profiles, existing property portfolios, or unconventional mortgage structures, the open market rarely offers a straightforward path. Private Finance exists to find that path on your behalf.
