Islay Robinson explains why high loan-to-value mortgages on prime residential properties require specialist lender relationships, careful structuring, and a tailored financing strategy.

When people hear the phrase "high-net-worth borrower," they often assume obtaining a mortgage becomes easier.

In reality, the opposite is frequently true.

I'm Islay Robinson, CEO and Founder of Enness Global, a specialist high-net-worth finance brokerage authorised and regulated by the Financial Conduct Authority (FCA 565120). Many of the clients who come to us have substantial wealth, but their financing requirements sit well outside conventional lending criteria.

A recent transaction is a good example.

The client wanted to purchase a prime UK residential property valued at several million pounds. Their objective was straightforward: preserve as much capital as possible, structure the borrowing on an interest-only basis, and keep monthly commitments relatively low during the early years of ownership.

Despite the client's strong financial position, arranging the finance was far from straightforward.

As property values increase, many lenders become progressively more conservative with maximum loan-to-value ratios. At the same time, interest-only lending at this level is typically available only to borrowers with clearly defined repayment strategies and through a relatively limited number of specialist lenders.

When those two requirements are combined, the pool of potential lenders becomes significantly smaller.

This is where lender selection becomes more important than lender comparison.

Rather than approaching the market broadly, we identified a private banking lender with genuine experience of high-value residential lending and an underwriting approach suited to the client's wider financial profile.

The facility was structured across multiple lending tranches to provide greater flexibility during the initial period of the mortgage. Just as importantly, the long-term repayment strategy was agreed with both the client and lender from the outset. The client fully understood how the interest-only structure operated and was comfortable that it aligned with wider financial and property plans.

The transaction completed with a high loan-to-value interest-only mortgage on terms that supported the client's objectives while preserving liquidity for other investments and financial priorities.

For me, this transaction reinforces an important point.

Complex mortgage transactions are rarely about persuading a lender to change its policy.

They are about understanding which lenders already have the appetite, experience, and underwriting flexibility to consider a particular borrower and structure.

That is often the difference between spending months pursuing the wrong solution and securing the right one from the beginning.

If you're purchasing a high-value property, have an unconventional income profile, or have already been told your borrowing requirements fall outside standard criteria, the first step is often understanding which parts of the market are genuinely equipped to help.

That conversation usually starts long before the mortgage application itself.
