TL;DR- UK expats can obtain mortgages to purchase UK property but are treated as non-resident borrowers - lender choice is more restricted than for UK residents.
- Expat mortgages are typically used to purchase a UK buy-to-let property or to buy ahead of a planned return to the UK.
- Overseas income must be converted to GBP and verified through payslips, tax returns or employer letters from the country of residence.
- Non-UK residents pay a 2% non-resident stamp duty land tax surcharge on UK residential property purchases.
What Is an Expat Mortgage?
An expat mortgage is a UK mortgage arranged for a UK national who is currently resident overseas. The borrower is purchasing UK property either as an investment (buy-to-let) or for future owner-occupation when they return to the UK. Because the borrower is not currently resident in the UK, mainstream UK lenders typically cannot proceed - expat mortgages are offered by specialist lenders that have underwriting processes for overseas income and non-resident borrowers.
Residential vs Buy-to-Let Expat Mortgages
Expat buy-to-let mortgages are more commonly available than expat residential mortgages. This is because a residential mortgage requires the property to be owner-occupied by the borrower, which cannot be the case if the borrower is living overseas. An expat residential mortgage is typically used where the borrower intends to return to the UK and occupy the property within a defined period - lenders will require a credible plan for this.
Expat buy-to-let mortgages are assessed on the standard rental income coverage criteria used for UK resident BTL applications, with additional requirements around overseas income verification and borrower identity.
Overseas Income Assessment
Overseas income must be verified to the lender's satisfaction. Acceptable documentation varies by lender and by the country of employment but typically includes: overseas payslips for the last three to six months; overseas tax returns or equivalent tax authority documentation; employer letters confirming salary and employment status; and bank statements showing income received. Income is converted to GBP for assessment purposes, often using a conservative exchange rate to account for currency risk.
The currency and country of employment affect lender appetite. Income in major currencies (USD, EUR, AUD, HKD, SGD, and others) from stable economies is more readily accepted. Income in less liquid or less stable currencies may be discounted more heavily or not accepted by some lenders.
Non-Resident Stamp Duty Surcharge
Non-UK residents purchasing UK residential property pay an additional 2% non-resident stamp duty land tax surcharge on top of standard SDLT rates in England and Northern Ireland. This surcharge has applied since April 2021. Equivalent additional charges may apply in Scotland (LBTT) and Wales (LTT). The surcharge applies based on the buyer's tax residency status at the time of purchase - UK nationals who are resident overseas are non-UK residents for this purpose. HMRC guidance and the GOV.UK stamp duty calculator provide current rates and thresholds.
Tax Considerations for UK Property Owned by Non-Residents
UK non-residents who receive rental income from UK property must declare it to HMRC through the Non-Resident Landlord (NRL) scheme. Tenants or letting agents are required to deduct basic rate income tax from rents unless HMRC has approved the non-resident landlord to receive rents gross. Capital gains tax applies to non-residents on disposal of UK residential property - HMRC must be notified within 60 days of completion of any disposal. Specialist UK tax advice for non-residents is strongly recommended.
Frequently Asked Questions
Can I get a UK mortgage while working in a country with no income tax?
Yes. Income earned in zero-tax jurisdictions (UAE, Qatar, Cayman Islands, etc.) can be assessed for UK mortgage purposes. Lenders require documentation confirming the income received - typically employer letters and bank statements, as there are no tax returns in these jurisdictions. Some specialist lenders are experienced with Gulf and other zero-tax jurisdiction income assessment. Currency stability and liquidity of the earning currency are factors in lender acceptance.
Do I need a UK bank account for an expat mortgage?
Most expat mortgage lenders require mortgage payments to be made from a UK bank account. If the borrower does not have a UK bank account, they may need to open one before completing the mortgage. Some international banks with UK branches can assist with this. The rental income on a BTL property can typically be used to fund the UK mortgage payments.
Can an expat mortgage be converted to a standard residential mortgage on return to the UK?
On returning to the UK and becoming resident, it is typically possible to remortgage to a standard residential or buy-to-let product, subject to meeting standard lender criteria at that time. The expat mortgage may carry a higher rate than UK resident products - returning to the UK usually opens up more competitive options. A new affordability assessment will be required.
Does the non-resident SDLT surcharge apply if I am a British citizen?
Yes. The non-resident SDLT surcharge applies based on residency status, not nationality. A British citizen who has been non-resident in the UK for the 12 months preceding the purchase pays the additional 2% surcharge. The test is based on the number of days spent in the UK during the 12 months before the purchase date.
