How a £1.875m interest-only mortgage supported a £2.5m London investment purchase
A high-net-worth family living in the United States needed a lender able to assess overseas income, global assets, limited UK credit history and a seven-figure borrowing requirement without forcing them into an ownership or deposit structure that compromised their wider plans.

Steve reviewed the family’s U.S. income, property wealth, repayment options and ownership considerations together, then researched lenders prepared to assess the strength of the complete balance sheet rather than relying on a conventional UK credit profile.
The case at a glance
- The challenge
- All applicants lived in the U.S., income came from several overseas sources, UK credit history was limited and the required loan exceeded £1 million.
- The solution
- A specialist lender supported £1.875 million at 75% loan-to-value on an interest-only, five-year fixed structure, with a credible repayment strategy.
- The outcome
- The family secured access to a lending solution for the proposed £2.5 million London acquisition while retaining capital and clarifying ownership before proceeding.
Substantial wealth did not remove the underwriting complexity.
The family wanted to acquire a prime London investment property valued at £2.5 million. Their overall financial position was strong, including substantial earned income, property wealth and a sizeable deposit. The difficulty was translating that U.S.-based financial profile into a structure a UK lender could underwrite comfortably.
- Multiple overseas income streams The primary applicant combined senior employed earnings with established consultancy income and government pension income, all generated outside the UK.
- A limited UK credit footprint The applicants were U.S. residents with only a modest UK banking relationship and no meaningful recent UK borrowing history.
- A seven-figure interest-only requirement The preferred borrowing exceeded £1 million and the family wanted interest-only payments, making lender appetite and the repayment strategy especially important.
- Personal ownership or an SPV The family were considering different ownership structures and wanted the finance decision to remain compatible with specialist tax and succession planning advice.
Several potential lenders were discounted because of tighter loan-to-value limits for overseas borrowers, maximum loan restrictions, UK credit requirements or a reluctance to recognise the consultancy income in full. The task was therefore not simply to prove affordability, but to find underwriting that could evaluate income, liquidity and assets together.
Structure the case around the whole balance sheet.
Steve positioned the application around the family’s overall financial resilience rather than a narrow earned-income multiple. That meant evidencing the different income sources clearly, demonstrating the wider asset position and presenting credible ways the interest-only capital could ultimately be repaid.
-
Identify lenders comfortable with the U.S. profile
Focus research on lenders prepared to assess U.S. residency, foreign income, limited UK credit history and a loan above £1 million within the same application.
-
Use the wider assets to support the repayment strategy
Property equity and investment holdings provided credible routes for repaying the capital at the end of the interest-only term.
-
Arrange £1.875m at 75% loan-to-value
The recommended facility matched the £2.5 million purchase with a 25% equity contribution and allowed lender fees to be added to the borrowing, reducing the immediate cash requirement.
-
Choose interest-only with five-year payment certainty
A five-year fixed rate gave payment certainty while the interest-only basis preserved more capital for other investment objectives.
A lending route that matched the family’s international profile.
The family secured access to a specialist lending solution capable of supporting the proposed £2.5 million London investment acquisition despite being entirely U.S.-based and having limited UK credit history.
The selected lender was prepared to assess employed earnings, long-established consultancy income, pension income and the broader asset position together. The final recommendation therefore balanced leverage, liquidity and payment certainty instead of forcing the family to commit a larger deposit simply to fit a narrower lending model.
For a high-net-worth international borrower, lender fit can depend as much on how global income, assets and repayment strategy are presented as on the headline level of wealth.
Keep the mortgage structure aligned with specialist tax advice.
The family were considering both personal and SPV ownership. From a lending perspective, each route changed the available lender pool: some corporate options imposed lower maximum loan-to-value limits or restrictions on the number of directors within the borrowing structure.
Rather than allowing the mortgage choice to dictate the ownership decision, Steve introduced the family to specialist tax advisers experienced in UK and international property ownership. This allowed the lending and tax discussions to progress together. Willow did not provide the tax advice; the objective was to make sure the finance could be considered alongside the family’s wider ownership and succession planning.
Understanding this type of cross-border purchase.
Can U.S. residents obtain a mortgage for a UK investment property?
Yes, some UK lenders consider U.S.-resident borrowers and investment purchases. Lender appetite varies according to residence, income currency, property use, deposit, ownership structure, credit evidence and the overall financial profile.
Does limited UK credit history prevent a mortgage application?
Not necessarily. A thin UK credit file can narrow the lender pool, but some lenders can assess overseas credit evidence, banking history, income, assets and liabilities as part of a broader underwriting review.
Can a mortgage above £1 million be arranged on an interest-only basis?
Some lenders may consider large interest-only loans where the case fits their criteria and there is a credible way to repay the capital. In this case, property equity and investment holdings supported the repayment strategy.
Should an overseas investor buy UK property personally or through an SPV?
There is no universal answer. Ownership can affect lender choice, loan-to-value, pricing, administration and tax treatment. Mortgage advice and appropriately qualified UK and international tax advice should therefore be coordinated before the structure is finalised.
A strong U.S. balance sheet still needs the right UK lender strategy.
