High-net-worth borrowers are increasingly treating debt as a strategic tool for managing wealth rather than simply a way to finance property purchases, as international buyers take advantage of greater choice and negotiating power in London’s prime housing market.
The shift towards more sophisticated borrowing strategies comes as the UK mortgage market shows signs of renewed confidence, with outstanding residential mortgage balances reaching ยฃ1.746 trillion during the first half of 2026 and new mortgage commitments rising to ยฃ78 billion, according to FCA Mortgage Lending Statistics for the first quarter.
Enness Global’s latest Private Client Finance Report found that affluent borrowers are placing greater emphasis on preserving liquidity, securing certainty of execution and structuring finance around their wider investment portfolios.
Specialist forms of lending, including securities-backed finance, bridging loans and cross-border facilities, have consequently continued to gain traction.
Islay Robinson, chief executive of Enness Global, said: “The strongest borrowers are often not the simplest. Increasingly, successful borrowing is less about accessing capital and more about structuring it intelligently around a client’s broader wealth position. Sophisticated borrowers are placing greater value on certainty of execution and preserving liquidity than simply achieving the lowest possible rate.”
The trend comes despite a more selective lending environment. Mortgage product availability reached its highest level since 2007, although more than 530 fixed-rate products were withdrawn during March as lenders rapidly repriced.
Enness expects about 1.8 million fixed-rate mortgages to expire during 2026, providing a further source of refinancing demand and increasing the need for specialist advice as borrowers reassess their financing structures.
London’s prime property market is also providing international investors with greater scope to negotiate.
Prime London housing supply increased 13.8 per cent year-on-year, while average discounts to asking prices widened to 10.5 per cent. Prime Central London prices remain about 7 per cent below their level a year earlier.
The combination of increased supply and softer pricing has helped create more favourable conditions for buyers, particularly those with the financial capacity to move quickly.
US purchasers remain among the most active international buyers, with technology, artificial intelligence and private equity professionals particularly prominent.
At the upper end of the market, transactions worth more than ยฃ5 million remain comfortably above pre-pandemic averages despite a year-on-year decline, suggesting continued resilience in the super-prime segment.
For wealthy borrowers, the appeal of debt is therefore increasingly linked to what they can do with capital they choose not to deploy.
Rather than tying up liquidity in a property purchase, borrowers can use bespoke financing to retain cash for investments or other opportunities while using leverage against existing assets.
That approach is particularly relevant for internationally mobile clients whose wealth may span property, businesses, investment portfolios and assets held across multiple jurisdictions.
Enness expects demand for bespoke lending to strengthen through the second half of 2026 as wealth structures become more international and complex.
The development points to a broader change in the private-client mortgage market: for the wealthiest borrowers, the question is becoming less about whether they can borrow and more about how intelligently debt can be incorporated into the management of their wider balance sheet.
