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.

Frequently asked questions
Can expats get a high net worth mortgage?
Yes, British expats can obtain high net worth mortgages on UK property. Lenders will consider the borrower's country of residence, currency of income, and employment or business structure. Foreign currency income is subject to exchange-rate risk rules introduced under the Mortgage Credit Directive (MCD).
Can an expat married to a foreign national get a joint UK mortgage?
Yes. In many cases expat and foreign national couples are eligible to borrow together through specialist lenders. The foreign national needs a legal right to reside in the UK, a three-year address history, and full identity and source-of-funds checks.
What is an expat mortgage?
An expat mortgage is a UK mortgage for borrowers living outside the UK. It is underwritten using expat criteria, focusing on residency, overseas income, currency exposure, and country risk rather than solely on nationality or UK credit history.
What is an expat BTL?
An expat buy-to-let (BTL) is a UK mortgage designed for British citizens or UK nationals living abroad who want to purchase or refinance a UK rental property. Lenders assess overseas income, currency exposure, and rental income to determine affordability and risk.
How do expat mortgages work?
Expat mortgages work by assessing borrowers on overseas residency rather than nationality. Lenders apply higher deposits, enhanced AML checks, conservative income conversion, and stricter stress testing to manage currency, enforcement, and country risk.
