How Foreign Currency Income & Liquidity-Based Lending Are Reshaping UK Mortgage Approvals in 2025

Foreign Income & Global Assets — How High-Net-Worth Buyers Are Securing UK Mortgages in 2025 Without Traditional Payslips or Domestic Earnings

Why Traditional Income Criteria No Longer Work for Many Buyers


In 2025, a growing number of high-net-worth individuals are earning in currencies other than GBP. From USD salaries and AED bonuses to EUR dividends or JPY fund distributions, foreign income is increasingly common — but it can still cause friction when applying for a UK mortgage.


At the same time, many buyers have substantial wealth tied up in investment portfolios, company shares, or global property — yet they struggle to meet standard affordability checks.


This is where liquidity-based lending comes in.

What Is Liquidity-Based Lending?


Liquidity-based lending allows borrowers to secure a mortgage using their asset base rather than provable income. It’s often offered by private banks and high-net-worth mortgage specialists and is based on:


  • Cash deposits held with the lender
  • Listed investments or managed portfolios
  • Net worth across property, equities, and business assets
  • Global holdings that can be evidenced and valued


Instead of assessing monthly income, the lender focuses on your ability to repay based on your liquid assets or overall financial position.

How Foreign Currency Income Is Treated in 2025


Lenders are more open to foreign income today — but strict rules still apply. Key considerations include:


  • Currency risk: how volatile is the income stream, and is it pegged or fixed?
  • Stability of source: is it a regular salary, dividend, or business income?
  • Taxation and location: is the client UK-domiciled or non-resident?
  • Documentation: bank statements, payslips, tax returns, or corporate confirmation


Some lenders will “shave” the income (e.g. applying a 20–30% haircut) to account for currency fluctuation. Others may only consider it if remitted to a UK account or held for a minimum period.

Which Clients Benefit From This Approach?


We’re seeing increased success with:


  • International buyers purchasing UK homes while earning abroad
  • Entrepreneurs who retain profits or receive irregular income
  • Clients with multi-currency holdings and global assets
  • Family offices and trust beneficiaries receiving offshore distributions
  • Investors with large stock portfolios or passive income streams


In these cases, a liquidity-based approach often unlocks higher loan amounts — without compromising investment strategy or tax efficiency.
