A high-net-worth American couple wanted to establish a long-term base in London, allowing them to spend regular periods in the UK while maintaining their primary residence in the United States. With substantial income, strong assets and a healthy deposit available, the purchase appeared straightforward on paper. However, their income structure, residency status and future usage plans created a level of complexity that ruled out many traditional lending options.

Working closely with the clients, Elizabeth Powell structured a solution that enabled them to secure a mortgage against a London second home despite relying on overseas income, self-employed earnings and stock-based remuneration.

For borrowers searching for ways of securing a UK mortgage with foreign income, RSUs and self-employed earnings, this type of scenario is increasingly common as international professionals seek access to the London property market.

Strong Wealth Position, Challenging Mortgage Profile

The clients were looking to purchase a second home in London within the following 12 to 18 months. Their focus was on modern developments offering strong transport links and professional management, including concierge-led buildings in locations such as Battersea, Bermondsey and areas benefiting from the Elizabeth Line.

They intended to contribute a 25% deposit from readily available savings and required a mortgage amount that was within a range dependent upon the eventual purchase price.

From a wealth perspective, the applicants presented exceptionally well. They owned their primary residence in the United States, had significant surplus income each month and carried very little debt outside of their existing residential mortgage.

The complexity lay elsewhere.

One applicant was a successful self-employed business owner generating substantial annual income through a sole proprietorship. The other worked for a major employer and received remuneration through a combination of base salary, performance-related compensation and restricted stock units (RSUs).

Traditional lenders often struggle to assess these income structures consistently.

While headline earnings can appear attractive, underwriters are required to determine which elements are sustainable, predictable and acceptable for affordability purposes. Income that is straightforward in one country can become significantly more difficult to assess when converted into another regulatory environment.

Why Many Lenders Were Unlikely to Proceed

The first challenge was residency.

The clients were US nationals who intended to spend only limited periods in the UK each year. Although they were purchasing for personal use rather than investment purposes, they were not UK residents and had no immediate plans to relocate permanently.

A large proportion of mainstream lenders simply do not lend to overseas applicants purchasing second homes.Those that do often impose additional restrictions, require larger deposits or limit the types of income they will accept.

The second challenge concerned the self-employed income.

While the business was highly profitable, the income was evidenced through US tax returns and business records rather than the UK documentation most lenders are accustomed to reviewing. Some lenders were unwilling to assess overseas self-employed income altogether.

Others would require extensive verification and potentially apply conservative affordability assumptions.

The third challenge involved RSUs.

This is an area where lender attitudes vary dramatically.

Some lenders exclude stock-based remuneration entirely. Others may consider it only where there is a long track record of receipt and evidence that the awards have consistently vested and been realised. Even then, many lenders will average income over several years and apply significant discounts.

From an underwriting perspective, RSUs can be viewed as less predictable than contractual salary. Share prices fluctuate, future awards are not always guaranteed and remuneration structures can change.

In this case, excluding the RSU income entirely would have materially reduced borrowing capacity despite it forming an established and meaningful part of the applicant's overall earnings.

Looking Beyond Standard Affordability Models

Rather than approaching the market through a traditional affordability-led process, Elizabeth Powell began by identifying lenders capable of understanding the broader financial picture.

This distinction was critical.

The clients were not suffering from affordability constraints. Their monthly surplus income was exceptionally strong and their overall financial position was robust. The challenge was finding a lender willing to recognise the quality of that income rather than simply rejecting the structure because it sat outside standard criteria.

Specialist lenders are able to take a more nuanced approach in these circumstances.

Rather than focusing solely on salary multiples, they often examine the consistency of earnings, the strength of supporting documentation, the client's wider asset position and the sustainability of income over time.

This enabled the discussion to move away from rigid lending formulas and towards a more comprehensive assessment of risk.

The lender selected was comfortable reviewing both US self-employed income and complex employed remuneration, provided sufficient evidence could be supplied.

This included two years of tax returns for the self-employed applicant and detailed employer confirmation regarding salary, bonus and RSU income for the employed applicant.

Structuring the Mortgage Around Long-Term Objectives

The clients wanted certainty.

Although interest-only borrowing was explored, their preference was for a structure that guaranteed the debt would be fully repaid by the end of the term.

A capital repayment mortgage therefore represented the most appropriate solution.

The recommended structure combined a 25% deposit with a 75% loan-to-value mortgage over a 30-year term.

This provided a balance between capital preservation and lender comfort.

A larger deposit could have reduced the monthly payment slightly, but retaining liquidity was strategically advantageous. The clients maintained access to capital while still presenting a strong equity contribution from the lender's perspective.

The selected lender also allowed significant annual overpayments, creating flexibility should the clients decide to reduce the balance more aggressively in future years.

An additional consideration involved the type of property being acquired.

Many of the developments being considered were newer buildings with strong energy efficiency credentials. This created access to preferential pricing where properties achieved higher EPC ratings.

While the difference in interest rate was relatively modest, it demonstrated how property selection itself can influence mortgage structure and borrowing costs.

Why the Final Structure Worked

The strength of the solution was not simply that finance was available.

It was that the structure aligned with the clients' broader objectives while addressing lender concerns at every stage.

The lender obtained comfort from the deposit size, strong asset position, substantial surplus income and clear evidence trail.

The clients retained liquidity, secured a predictable repayment structure and gained a permanent foothold in the London market without disrupting their existing financial arrangements in the United States.

Importantly, the mortgage was designed around the reality of how internationally mobile professionals earn income today.

This type of scenario is increasingly common as compensation structures become more sophisticated and high-net-worth individuals operate across multiple jurisdictions. Traditional lenders often struggle to accommodate these cases because their systems are built around straightforward domestic employment.

Specialist lenders are able to assess the underlying strength of the borrower rather than relying exclusively on standardised income models.

The same principles frequently arise in expat mortgage scenarios, applications involving complex income structures and cases where borrowers earn across multiple currencies.

Key Takeaways

What made this case possible was not the clients' income alone, but the ability to present that income in a way lenders could understand and verify. Overseas residency, self-employed earnings and RSUs all create underwriting challenges, even for high-net-worth borrowers.

Many lenders would have struggled with some or all elements of the application. Some would not consider overseas applicants. Others would exclude RSU income or refuse to assess foreign self-employed earnings. By identifying a lender whose underwriting approach matched the reality of the clients' circumstances, it became possible to secure a structure that reflected their true financial strength.



For similar borrowers, preparation is often the deciding factor. Establishing how different income streams will be assessed, gathering the correct evidence and selecting lenders with relevant expertise can have a significant impact on both borrowing capacity and overall outcomes.

In complex international cases, specialist advice is often less about finding a lender and more about finding the right lender.
