Expat Mortgages: Buying UK Property While Living Abroad
Updated 10 April 2026
The Expat Mortgage Process
If you live and work outside the UK and want to purchase residential or investment property back home, you will likely need a specialist expat mortgage. Most high-street lenders do not offer mortgages to applicants based overseas, which means the right lender, the right criteria match and the right presentation of your case all matter from the outset. Mortgage One advises expat clients on UK mortgage applications for purchases, helping you understand your options, prepare the right documents and avoid common delays.
Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.
Please note: We are only able to provide regulated mortgage advice to clients who are physically present in the UK at the time the advice is given.

Who Expat Mortgages Are For
Expat mortgages are designed for borrowers who are not currently living in the UK but want to buy UK property. In practice, that includes British nationals working overseas, returning expats planning to move back, and overseas-based borrowers purchasing buy-to-let property in the UK.
Your eligibility will depend on a combination of factors including your country of residence, nationality, income type, currency of earnings, deposit size and UK credit history. Even if you do not currently have a UK address or UK bank account, a well-prepared application can still proceed — provided the lender's criteria are met. If you hold a foreign nationality rather than British citizenship, the lender may apply separate foreign national mortgage criteria alongside or instead of their expat policy.
How Lenders Assess Expat Purchase Applications
Lender criteria vary, but most expat mortgage applications for purchases are assessed around the same core issues.
Country of residence. Some lenders restrict the countries they will consider. Applicants in sanctioned or high-risk jurisdictions may find their options significantly narrower.
Income type and evidence. Employed applicants usually need payslips, an employment contract and bank statements. Self-employed or company director applicants will typically need two or more years of accounts or tax returns. Contract workers may need to show continuity of engagement and evidence of future earnings.
Currency of income. Lenders that accept overseas income in a foreign currency will usually apply a currency discount — sometimes called a haircut — of around 10 to 25 per cent to account for exchange rate risk. This reduces the amount of income used in the affordability calculation.
Deposit and source of funds. Expat purchase mortgages commonly require a deposit of at least 25 per cent, though this varies by lender and case. You will need to demonstrate where the deposit has come from, particularly if funds are held in overseas accounts or have been gifted. For more on how deposits are assessed, see the mortgage deposits explained guide.
UK credit profile. Even if you have been abroad for several years, your UK credit file can still influence the outcome. Some lenders require a clean UK credit history; others are more flexible where the applicant has limited recent UK credit data. You can check your credit file before applying.
Property purpose. Whether you are buying a residential home for future use or a buy-to-let investment will determine which lender criteria apply. Buy-to-let cases are often assessed differently, with rental income playing a central role in affordability. If you are considering a UK investment property, the expat buy-to-let mortgage criteria guide covers what lenders are looking for.
Stamp Duty for Expat Buyers
If you have been outside the UK for most of the 12 months before your purchase, you are likely to be classed as a non-UK resident for Stamp Duty Land Tax purposes. This means you may pay a 2 per cent surcharge on top of the standard SDLT rates in England and Northern Ireland. If you are also purchasing an additional property — for example, a buy-to-let — the 5 per cent additional property surcharge applies as well, bringing the total surcharge to 7 per cent above standard rates. You can estimate your liability using the Mortgage One stamp duty calculator.
If you move to the UK and spend at least 183 days here within 12 months of the purchase, you may be able to claim a refund of the 2 per cent non-resident surcharge. This must be claimed within two years of the purchase. SDLT does not apply to purchases in Scotland or Wales, which have their own land transaction taxes.
Stamp duty can be a significant additional cost for expat buyers. Mortgage One does not provide tax advice, but we always recommend that you speak to a qualified solicitor or tax adviser before completing a purchase so that you understand the full cost position.

Documents You Will Usually Need
The exact paperwork depends on the lender and the type of case, but expat purchase applicants commonly need the following.
Valid passport and proof of current overseas address
Income evidence — payslips, employment contract, letter from employer, company accounts or tax returns depending on how you are paid
Bank statements — usually three to six months showing salary credits, regular income and deposit funds
Evidence of deposit — including source of funds documentation where the deposit is held overseas, has been gifted or has come from the sale of another property
Details of the property being purchased — including estate agent particulars and any tenancy details for buy-to-let cases
Existing mortgage details — where you already own UK property
Getting documents in order early can make a significant difference to processing times. Mortgage One will guide you through the paperwork needed for your specific case.
How the Process Works
The expat mortgage process follows a similar structure to a standard UK application, but with additional steps around identity verification, overseas document certification and source of funds checks.
The typical stages are an initial discussion about your goals, income, deposit and property plans; a review of the lender criteria most relevant to your case; document collection and application preparation; agreement in principle; valuation and underwriting; and finally mortgage offer, solicitor instruction and completion.
Expat cases can take longer than a standard UK application. International document checks, time zone differences and lender queries about overseas income or deposit sources can all add time. Working with a broker who understands the process can help avoid unnecessary delays.
Why Speak to Mortgage One
Mortgage One advises on expat mortgage cases where lender criteria, income structure and overseas residency make the application more specialist than a standard UK case. When you speak to Mortgage One, the aim is to identify which lenders are likely to fit your case, explain the document requirements, and structure the application so that it is presented clearly and completely from the outset.
Mortgage One does not provide tax or legal advice. If your purchase involves cross-border tax considerations, ownership structures or inheritance planning, you should also speak to a qualified solicitor or accountant.

FAQs
1. Can I get a UK mortgage if I live abroad? In many cases, yes. Eligibility depends on your country of residence, income type, currency, deposit, UK credit history and the lender's criteria at the time of application. Not all lenders accept expat cases, which is why working with a specialist broker can help identify the right options.
2. How much deposit do I need for an expat mortgage? Most expat purchase mortgages require a deposit of at least 25 per cent, although this varies by lender, property type and loan-to-value. Some lenders may accept a lower deposit in specific circumstances; others may require more.
3. Will my overseas income be accepted? Many lenders accept overseas income, but they may apply a currency discount to account for exchange rate risk. The currencies accepted, the size of the discount and the evidence required all vary between lenders. See the overseas income mortgage guide for more detail.
4. Do I have to pay extra stamp duty as an expat? If you have spent fewer than 183 days in the UK in the 12 months before your purchase, you will likely pay a 2 per cent non-resident surcharge on top of standard SDLT rates. If you are also buying an additional property, the 5 per cent additional property surcharge applies as well. You may be able to reclaim the non-resident surcharge if you subsequently meet the UK residency test within 12 months. Mortgage One does not provide tax advice - we always recommend that you speak to a qualified solicitor or tax adviser so that you understand the full cost position.
5. Can I buy a UK buy-to-let property while living abroad? Yes, some lenders offer expat buy-to-let mortgages. These are assessed differently from residential cases, with rental income and property type playing a central role. See the expat buy-to-let criteria guide**[Link6]** for current lender positions.
6. What if I plan to return to the UK? Returning expats can sometimes use their anticipated UK residency to support the application, but this depends on the lender and how close the planned return date is. Some lenders will consider a case on a residential basis if the return is imminent; others require the borrower to already be in the UK.
7. How long does an expat mortgage application take? Timescales vary, but expat cases often take longer than a standard UK application. International document checks, source of funds verification and time zone differences can all extend the process. A well-prepared application with complete documentation from the outset will usually move faster.
