What Is an Expat Mortgage? Who Qualifies and How to Apply
Updated 25 October 2026
An expat mortgage is a UK mortgage for a borrower who lives and works outside the UK, offered by lenders that accept overseas residence, foreign currency pay and documents issued abroad. On criteria checked on 25 October 2026, HSBC lends to non-UK residents in 14 approved countries at up to 75% loan to value, and Suffolk Building Society offers expat residential deals up to 90%. Who qualifies turns on where you live, how you are paid and what the property is for, not on your passport alone. Mortgage One is a whole of market mortgage adviser that places British expats with the lenders whose country, currency and income rules fit their case.

What is an expat mortgage and how is it different?
An expat mortgage is an ordinary UK repayment or interest-only mortgage that a lender has agreed to offer to someone living abroad. The difference is the underwriting: the lender sets a country list, an accepted currency list, a minimum income and usually a lower loan to value cap, such as 75% at HSBC for non-UK residents.
Expat lending sits with a short list of banks and building societies that publish an expat process. Some, such as Skipton International, lend on buy-to-let only. Others, such as Suffolk and Saffron, lend on a home your family lives in or one you plan to return to. That split between a home and a let property decides the lender list before price does, and for the price itself our table of current expat mortgage rates sets each lender's fixed rates side by side.
Who counts as an expat to a UK mortgage lender?
To most UK lenders an expat is someone living outside the UK when they apply, whatever their nationality. Some narrow it further: Suffolk Building Society asks for at least one UK or Irish passport holder, Saffron wants direct family living in the property or your return before completion, and Skipton International turns away residents of Australia and the EU.
Family Building Society reads the word more widely and also lends to UK and foreign nationals working in the UK but paid in a foreign currency. HSBC works from a country list instead: residents of Australia, Egypt, Guernsey, Hong Kong, the Isle of Man, Jersey, Malaysia, the Philippines, Qatar, Singapore, Switzerland, Taiwan, the UAE and the USA can apply for its non-UK resident mortgage. A borrower with no UK nationality at all faces a different lender set, compared in our guide to non-UK resident mortgages. If you are moving back to Britain within months, the returning expat mortgage guide explains how lenders treat a borrower in transition.
Can expats take out a UK mortgage? Which lenders say yes
Yes. On criteria checked on 25 October 2026, nine conventional UK lenders publish expat lending: HSBC, HSBC Expat, NatWest International, Skipton International and the Suffolk, Family, Marsden, Market Harborough and Saffron building societies. Each sets its own countries, currencies and loan to value cap, so a yes from one lender says nothing about the next.
· HSBC UK: non-UK residents in 14 approved countries, a home at up to 75% loan to value with basic income of at least £75,000, or buy-to-let with income of £50,000 (£75,000 self-employed) and a 25% deposit, rising to 40% above £1 million.
· HSBC Expat: UK buy-to-let for HSBC Expat customers at up to 75% loan to value over a maximum term of 25 years.
· NatWest International: applications through FCA regulated brokers only, up to 80% on a home to live in and 75% on buy-to-let, with loans from £100,000 for new customers.
· Skipton International: buy-to-let only in England, Wales and Scotland, a minimum loan of £100,000 (£150,000 on its 110% rental cover route) and up to 75% on loans to £1.25 million.
· Suffolk Building Society: a family home in England or Wales, one applicant earning £40,000 or the equivalent and expat residential products up to 90%, with a £650,000 maximum loan at that level.
· Family Building Society: expats in over 40 countries, up to 80% on a home and 75% on buy-to-let, with owner-occupier cases through brokers.
· Marsden Building Society: expat residential lending with currency haircuts of 10% to 20%, and no lending to residents of Australia or the EU and EEA.
· Market Harborough Building Society: lends to expats without a UK residency or multinational employer condition, at up to 80%.
· Saffron Building Society: up to 90% on loans to £1 million, sterling income only, for expats returning to the UK or whose direct family stays in the home.
How to apply for a UK expat mortgage, step by step
Applying for a UK expat mortgage runs in six steps: match your case to the lenders that accept your country and currency, gather documents, obtain a decision in principle, submit the full application, pass valuation and underwriting, then receive the offer and complete. NatWest International takes applications only through regulated brokers, so the route in matters too.
· Match your country of residence, income currency and property purpose to the lenders that accept all three.
· Collect identity, address, income and deposit documents, with English translations where a lender asks for them.
· Obtain a decision in principle. Market Harborough runs a soft search at that stage that leaves no footprint on your file.
· Submit the full application with the documents.
· Valuation, underwriting and any questions from the lender's underwriter.
· Mortgage offer, conveyancing and completion.
HSBC asks a non-UK resident buying a home to complete the application with one of its advisers, and holds all documents and mortgage meetings in English. Matching the case first is the step an expat mortgage broker runs across the whole specialist panel, and the buy UK property from abroad guide covers the purchase itself once a lender is lined up. Before any full application it helps to read your UK credit file, and you can download your credit report before you speak to an adviser.
Which documents do expat mortgage lenders ask for?
Expect a passport, proof of your overseas address, payslips or accounts, bank statements, deposit evidence and, on a remortgage, your latest mortgage statement. Lenders add their own rules: NatWest International wants proof of address less than six months old, and Saffron needs any document not in English translated by a qualified translator.
Self-employed borrowers carry more paperwork. Skipton International asks for two years' trading and an accountant's certificate or the latest tax assessment in English from the local tax office, and a first-time landlord needs 24 months' employment history against 12 months for an existing owner. NatWest International takes full bank statements as postal copies or online downloads, uncertified, but not screenshots. Deposit evidence matters as much as deposit size: Suffolk accepts a deposit built up in a foreign currency as long as it is held in the UK or your country of residence.
How do UK lenders treat foreign currency income?
Many expat lenders convert foreign pay into sterling and then cut it by a haircut before the affordability test. NatWest International counts 90% of converted income, a 10% haircut, while Marsden takes 10% off US dollars and euros, 15% off UAE dirham and Singapore dollars and 20% off Canadian and Australian dollars.
The haircut feeds straight into borrowing. A salary worth £100,000 at today's exchange rate counts as £90,000 at NatWest International, and as £85,000 at Marsden if it is paid in dirham, converted at the closing rate on the date of application. Currency lists differ as well. Suffolk Building Society accepts income in 15 currencies besides sterling, from the euro and US dollar to the Qatari riyal and Danish krone. Market Harborough takes US, Canadian, Hong Kong and Singapore dollars, euros, Swiss francs and other EU currencies as standard and considers the rest. Saffron accepts sterling income only.
To have your salary run through each lender's own currency haircut before you choose one, call 01202 155992 or contact Mortgage One.
How much deposit do you need for an expat mortgage?
Among the nine lenders checked, most expat purchases need a deposit of 20% to 25%, because the caps are 75% at HSBC, HSBC Expat and Skipton International and 80% at NatWest International, Family and Market Harborough. Suffolk and Saffron go to 90% on a home for borrowers who meet their passport, family or sterling rules.
Bigger loans lower the ceiling. Skipton International lends 75% up to £1.25 million, 70% to £1.5 million and 65% to £3 million. HSBC asks non-UK resident landlords for 25% down, rising to 40% on mortgages above £1 million. Suffolk's 90% products stop at a £650,000 loan and Saffron's at £1 million, and NatWest International drops to 75% on a new build flat.
How much can an expat borrow on a UK mortgage?
On a home, expat borrowing is set by an income multiple applied after any currency haircut. NatWest International lends up to 5 times income with a £50,000 minimum across the applicants, so £90,000 of counted income supports up to £450,000. On buy-to-let the rent sets the limit instead, through the lender's rental cover test.
Minimum incomes are a gate before any multiple applies: £75,000 basic at HSBC on a residential case, £50,000 employed or £75,000 self-employed for a sole applicant at Skipton International on buy-to-let, and £40,000 or the equivalent at Suffolk. Outgoings and the loan to value cap are checked after the multiple, so the lowest of the three limits is the one that counts. Our expat mortgage calculator runs the haircut, the multiple and the loan to value cap together on your own figures, so you can see which limit bites first.
Expat residential mortgages against expat buy-to-let
A residential expat mortgage is assessed on your income and is for a home your family lives in or you will return to. Expat buy-to-let is assessed mainly on rent: Skipton International asks for rent covering 125% of the interest, and Family Building Society sets no minimum income and no portfolio limit on expat buy-to-let.
That makes buy-to-let the wider market for an expat who will not live in the property soon. Skipton International, HSBC Expat and NatWest International all lend on it, and NatWest International takes up to 10 buy-to-let properties including the one being bought. Residential lending is narrower and leans on building societies: Suffolk requires a family residence in England or Wales that is not let, and Saffron requires the home to be occupied by direct family or by you on return.
If you already own the property and the deal is ending, our expat remortgage guide covers switching from abroad. A company purchase adds its own lender rules, set out in the expat limited company buy-to-let guide, and Mortgage One does not advise on tax, so speak to a qualified accountant before choosing a structure.
What an expat mortgage costs, including the stamp duty surcharge
Beyond the rate, budget for lender fees, valuation, legal costs, translation or certification, currency transfer costs and Stamp Duty Land Tax. A buyer not present in the UK for at least 183 days in the 12 months before purchase usually pays a 2% surcharge on residential property in England or Northern Ireland, on top of the standard bands.
On a £300,000 home that is your only residential property, the standard bands come to £5,000 and the 2% surcharge adds £6,000, so £11,000 in total. If you already own another residential property, the 5% higher rates usually apply as well, and gov.uk sets out when the surcharge can be refunded. Our stamp duty calculator for UK property runs the surcharge alongside the standard bands. Scotland and Wales run their own property taxes, so ask your solicitor about a property there. Lender fees vary too: Family Building Society charges a £175 application fee plus valuation on its expat products, and HSBC Expat's buy-to-let fixes carry a £999 booking fee, or none on its Fee Saver range.
How long does an expat mortgage application take?
An expat case usually takes longer than a UK one because every document crosses a border. The time goes on certification, translation, international post and underwriter questions about foreign income. NatWest International's proof of address must be under six months old, so documents gathered too early can expire before the offer arrives.
The quickest cases are the ones where the lender match is settled before the first document is ordered, because a decline at underwriting sends the whole file back to the start with a different lender's list.
What goes wrong on expat mortgage applications
The common failures are criteria mismatches found late: a country the lender does not serve, a currency it does not accept, income below its minimum or a loan below its floor. Skipton International will not lend under £100,000, and Marsden turns away residents of Australia and the EU and EEA, however strong the rest of the case.
Other avoidable problems follow the same pattern. A deposit moved between accounts in several countries without a paper trail stalls underwriting. A home left empty fails Saffron's occupation rule. A self-employed applicant short of two years' trading falls outside Skipton International.

FAQs
1. Can I take out a UK mortgage while living abroad? Yes, if a lender accepts your country of residence, your income currency and the property's use. HSBC, NatWest International, Skipton International and several building societies publish expat lending, each with its own country list, minimum income and loan to value cap.
2. What is the difference between an expat mortgage and a normal mortgage? The mortgage product is the same, but the lender underwrites for life abroad: it checks your country, converts and often discounts foreign pay, and caps the loan to value lower, commonly at 75% or 80%.
3. How much deposit do I need for an expat mortgage? Usually 20% to 25%. HSBC and Skipton International cap at 75% loan to value and NatWest International, Family and Market Harborough at 80%, while Suffolk and Saffron reach 90% on a home for borrowers who meet their passport, family or sterling income rules.
4. Does foreign currency income count for a UK mortgage? Yes, at most expat lenders, after a haircut. NatWest International counts 90% of converted income, Marsden takes 10% to 20% off depending on the currency, Suffolk accepts 15 currencies besides sterling and Saffron accepts sterling income only.
5. Do I pay extra stamp duty as an expat? Usually, in England and Northern Ireland. If you were not present in the UK for at least 183 days in the 12 months before buying, a 2% surcharge applies on top of the standard rates, so a £300,000 only home costs £11,000 in Stamp Duty Land Tax instead of £5,000.
6. Which documents should I prepare before applying? A passport, proof of overseas address under six months old, payslips or accounts, full bank statements, deposit evidence and, on a remortgage, your latest mortgage statement. Self-employed applicants also need two years' trading figures, and documents not in English may need a qualified translation.
7. Can expats take out a buy-to-let mortgage in the UK? Yes, and buy-to-let is the wider expat market. Skipton International, HSBC Expat, NatWest International and Family Building Society all lend on it, assessing mainly the rent, with Skipton International asking for rent covering 125% of the interest on loans from £100,000.
8. Is it worth using a broker for an expat mortgage? Often, because several expat lenders work through brokers: NatWest International accepts applications only from FCA regulated brokers, and Family Building Society takes owner-occupier expat cases through intermediaries. A broker also compares haircuts, country lists and minimum loans across the panel before any application is submitted.
