## Expat and foreign national high net worth mortgages

High net worth mortgages are available to British expats and foreign nationals purchasing or refinancing UK property, subject to lender criteria on residency, visa status, and source of funds. International HNW cases are typically served by private banks and specialist lenders with international underwriting capability.

Foreign currency income introduces additional considerations. Where a mortgage is regulated and the borrower’s income is in a foreign currency, lenders must consider exchange-rate risk under rules introduced following the Mortgage Credit Directive (MCD), which can affect the currencies accepted and the affordability assessment applied.

Anti-money-laundering checks and source-of-wealth evidencing are more extensive on international HNW cases. Preparing documentation early, including evidence of income, assets, and the origin of the deposit, keeps the application on track.
