Start Your CheckWhat is an expat mortgage calculator?
If you're a British expat living and working overseas and want to buy or remortgage a property in the UK, your application is assessed differently to a UK-resident applicant's. Lenders look at where you live, the currency your income is paid in, and often ask for a larger deposit — and not every UK lender accepts expat applications at all.
This calculator runs your details against the lenders we track, filters out the ones whose published criteria don't fit your situation (income currency, deposit), and gives you a conservative estimate of what the remaining lenders might offer. It's an information tool, not a mortgage offer or advice — see which lenders are worth focusing on before you approach anyone directly.
How expat mortgage affordability differs
The biggest difference for most expat applicants is how lenders treat foreign-currency income. Because exchange rates move, UK lenders generally don't count 100% of income paid in a foreign currency towards your affordability — they apply a reduction, sometimes called a haircut, as a buffer against currency movement.
- Widely-traded currencies — for example the US dollar, euro, Swiss franc, UAE dirham, Australian dollar, Canadian dollar, Singapore dollar, Hong Kong dollar, New Zealand dollar, Saudi riyal or Qatari riyal — lenders typically use around 75% of the income shown, as a conservative planning figure.
- Less commonly-traded currencies — lenders are generally more conservative still, often using a smaller proportion of the stated income.
- GBP-paid income— where your salary is already paid in sterling (for example some armed-forces or overseas-secondment roles), this reduction typically doesn't apply.
The exact percentage is set lender-by-lender and isn't published as a single industry-wide rule, so treat any figure here as an estimate rather than a guarantee for a specific lender. On top of the income treatment, many expat lenders also cap the maximum loan-to-value below what they'd offer a UK-resident applicant, and some ask for a higher minimum income before they'll consider an application at all. Our calculator applies these factors to your figures so you can see a realistic spread across lenders rather than one generic number.
Who this calculator is for
This tool is built for UK/British citizens living and working abroadwho want to buy or remortgage a property in the UK — whether that's a home to move back into, or a property to let out while you're overseas. We cover applicants based in a range of countries, including:
If you're not a British expat but a foreign national wanting to buy in the UK — for example on a work visa without indefinite leave to remain — our foreign nationals mortgage guide covers that situation instead. For a deeper look at how any foreign-currency income is assessed, read our foreign-currency income guide.
Which lenders does the calculator check?
We track 102UK lenders' published criteria for expat applications. Of those, 47 currently show evidence of accepting or considering British expat applicants, split into two groups:
- 22 lendersare checked instantly through our calculator's affordability engine — you get an estimated maximum for each as soon as you submit your details.
- 25 lendersare specialist or manual-route lenders. Where one of these looks like a fit for your situation, our calculator flags it, but you'd typically need to go through a broker for a full quote from that lender.
The remaining lenders in our wider tracked set either don't publish expat-specific criteria or don't currently accept expat applications on the evidence we've reviewed — being excluded here isn't a judgement on the lender generally, just on expat criteria specifically.

Frequently Asked Questions
Can I get a UK mortgage while living abroad?
Yes, in principle. A number of UK lenders — mainstream banks, building societies and specialist expat lenders — will consider mortgage applications from British expats living and earning overseas. Which lenders are open to you depends on your country of residence, the currency your income is paid in, your deposit, and the property itself. Our calculator checks your details against the lenders we track and shows you which ones fit.
Why do lenders use less of my foreign income than my payslip shows?
Most UK lenders apply a reduction to income paid in a foreign currency, to allow for exchange-rate movement between your application and any point in the future. For income in a widely-traded currency (for example the US dollar, euro, Australian dollar or UAE dirham), lenders typically use around 75% of the income shown on your payslip. For less commonly traded currencies, the reduction is often larger. The exact percentage is set lender-by-lender, so treat this as a conservative planning figure rather than a fixed rule.
Do I need a UK-based guarantor or co-applicant?
Not with every lender, but some expat mortgage products do ask for a UK-resident guarantor or joint applicant, particularly at higher loan-to-value bands. This varies product-by-product, so it's worth checking as part of your specific application rather than assuming either way.
Which UK lenders consider expat applications?
Of the 102 UK lenders we track, 47 currently have published criteria or evidence of considering applications from British expats — a mix of high-street banks, building societies and specialist buy-to-let lenders. Some can be checked automatically through our calculator; others are specialist or manual-route lenders where you'd typically go through a broker for a full quote. Our calculator tells you which group each lender falls into.
Will checking my affordability here affect my credit score?
No. Our calculator does not perform any credit search. We check published lender criteria and run affordability calculations only — your credit file is not accessed or affected in any way.
Information only — not mortgage advice. We are not FCA authorised. Being shown a lender does not mean you will be accepted, and figures shown are conservative estimates, not offers. Always speak to a qualified, FCA-authorised mortgage adviser before applying.
