International Mortgages for Expats Buying Property Abroad

Buying property abroad is one of the most significant financial decisions an internationally mobile individual makes, and financing that purchase introduces a set of complexities that do not arise with a domestic mortgage. International mortgage lenders, non-resident underwriting criteria, LTV ratios that differ from UK norms, currency risk between income and repayment, and an unfamiliar legal and conveyancing process all require careful navigation.

This guide explains the key features of international mortgages for expats, the main lenders, what documentation you will need, and how to approach the process.

What makes international mortgages different

Lender availability. UK high-street banks will generally not lend against properties abroad. You need either a local lender in the country where the property is located, or a specialist international mortgage provider. The pool of lenders is smaller, competition less intense, and rates often higher than in the UK domestic market.

LTV ratios. Lenders apply more conservative loan-to-value ratios for non-resident borrowers than for residents. A maximum LTV of 60–70% is standard across most markets — meaning a deposit of at least 30–40% of the purchase price is required. Some lenders will stretch to 75% for well-qualified borrowers with strong income and established banking relationships. Very few will exceed 75% for non-residents.

Income verification. Non-resident income is harder to verify than domestic income, and lenders apply additional scrutiny. Foreign payslips, tax returns from multiple jurisdictions, accounts in foreign languages, and variable income from self-employment or business interests all add complexity. Lenders may apply a haircut to foreign income (using a proportion of reported income rather than the full amount) to allow for currency risk or uncertainty.

Currency risk. If your income is in a different currency to your mortgage repayments, exchange rate movements affect the real cost of the mortgage. A GBP earner with a EUR mortgage in Spain will find their effective monthly cost varies with the EUR/GBP rate. Lenders are aware of this and apply currency stress tests. Borrowers should also manage this actively — forward contracts for mortgage payments, holding the payment currency in reserve, or matching income currency to mortgage currency where possible.

Legal and conveyancing differences. The property purchase process varies significantly by country — notarial systems (France, Spain, Portugal, Germany), title insurance and escrow (US, Australia), land registration processes — and requires local legal advice in addition to mortgage arrangement. The mortgage timeline is often longer than a UK purchase, particularly where documentation from multiple jurisdictions must be verified.

Key international mortgage lenders

HSBC Expat. HSBC Expat (based in Jersey) is one of the most significant international mortgage lenders for UK expats. It lends against UK property for non-resident borrowers (expat mortgages on UK property) and, depending on circumstances, may be able to facilitate finance in other markets through the HSBC global network. HSBC Expat mortgages require an HSBC Expat banking relationship.

Santander International. Based in Isle of Man, Santander International provides mortgages for UK expats buying UK property and may have facilities in other markets. Like HSBC Expat, it requires an existing banking relationship.

Local lenders in each market. In many countries, the most practical route is a local mortgage lender — a major bank in Spain, France, UAE, or Cyprus — that has experience working with non-resident buyers. Local lenders know the property registration system, have conveyancing relationships, and can process the mortgage within the local legal framework. Their non-resident criteria vary widely, and local mortgage brokers with non-resident experience are valuable.

Private banks. For high-value purchases, private banks with a Lombard lending or portfolio lending capability may be able to provide financing against a broader asset base — particularly where the borrower has significant investable assets that can be held with the bank as additional collateral. This is more flexible than a standard mortgage but requires an HNW client relationship.

Documentation typically required

The documentation list for an international mortgage application is extensive. Allow ample time to gather all of the following:

• Valid passport (certified copy)
• Proof of current address in country of residence
• Evidence of income — payslips (typically three months), employment contract (for employed borrowers); audited accounts and accountant's certificate (for self-employed or business owners)
• Most recent tax return from country of residence
• Bank statements — typically six to twelve months, showing income deposits and regular outgoings
• Existing mortgage statements if applicable
• Credit report from country of residence (and UK if relevant)
• Details of other assets and liabilities (investment portfolios, other properties, other borrowings)
• Reference letter from existing bank
• Details of the property — title, valuation, planning permissions
• Legal documents as required by the local jurisdiction

For self-employed or business-owner borrowers, the documentation requirement is more extensive and typically includes audited company accounts, director's loan accounts, and evidence of dividend history.

Currency risk management

Currency risk in an international mortgage operates in two main directions:

Purchase currency risk. Between agreeing to buy a property (at an agreed price in the local currency) and completing the purchase, exchange rates may move against you, increasing the sterling cost of the purchase. A forward contract at the time of exchange fixes the sterling cost regardless of what happens to exchange rates before completion.

Ongoing repayment currency risk. If your income is in a different currency to your mortgage, monthly payment costs fluctuate with exchange rates. Mitigation options include: holding a reserve of the mortgage currency (building up a buffer that absorbs short-term rate volatility), setting up forward contracts for a year's worth of payments at a time, or using a natural hedge where possible (holding assets denominated in the mortgage currency).

Tax and legal considerations

Mortgages on foreign property have tax implications that must be understood before proceeding. Interest on a buy-to-let mortgage abroad may be deductible against rental income in the property's country — but the rules vary. In the UK, non-residents are subject to UK tax on rental income from UK property. Interest deductibility in the UK has been restricted since 2017 for residential let properties.

Local legal advice in the property's jurisdiction is essential — both for the purchase process and for the mortgage structure. Some countries restrict foreign ownership or the forms of security available to foreign lenders.
