For many British expats, UK property is a financial anchor they hold onto. It might be a former home they now rent out, or a buy-to-let property bought to stay connected to a market they know and trust. Owning property feels tangible and familiar, but the real question is how it fits their wider plan from abroad.
However, owning UK property from abroad brings extra costs, taxes, and paperwork that resident landlords do not have to deal with. The key is to see the full picture, from getting a mortgage to selling the property, so that you can make informed decisions.
Getting a mortgage as a non-resident
The first challenge is getting the loan. It’s harder to finance a UK property from overseas than it is if you live in the UK.
Fewer lenders are available: Many mainstream UK banks do not lend to non-residents, so you will often need to look at specialist expat lenders, international branches of UK banks, or private banks.
A bigger deposit: You will usually need a bigger deposit than a UK resident. Often, this means putting down 25% or more, and sometimes much higher depending on the lender and your country of residence.
Higher rates and more scrutiny: Non-resident and expat mortgages usually have higher interest rates, and lenders will examine your income more closely. They may treat foreign-currency earnings differently, and some lenders may discount them or not accept income from certain countries or currencies.
The key takeaway is to start early and be prepared for a slower process with more paperwork than buying property in the UK as a resident. In most cases, working with a broker who specialises in expat mortgages is worth the cost, because the process is only the first step.
The tax on the way in: stamp duty, stacked
This is often where expats get the biggest surprise, as the surcharges add up quickly. If you buy a property in England or Northern Ireland (Scotland and Wales have their own systems), a non-resident buying an extra property like a buy-to-let faces three charges:
The standard SDLT rates
The additional-property surcharge, now 5%, which was raised from 3% in the October 2024 Budget
The non-resident surcharge of 2%, which is added on top of the other charges
The difference is significant. A non-resident buying a £500,000 second property pays about £50,000 in stamp duty. This includes around £15,000 of standard duty, £25,000 for the additional-property surcharge, and £10,000 for the non-resident surcharge. A UK resident buying the same property as their only home would pay much less.
Two important things to know. For SDLT, you are considered non-resident if you spent fewer than 183 days in the UK in the 12 months before buying. If you become a UK resident within 12 months after your purchase, you can reclaim the 2% non-resident surcharge.
The tax while you own it: the Non-Resident Landlord Scheme
Rental income from a UK property is always taxed in the UK, no matter where you live. For overseas landlords, HMRC collects this tax through the Non-Resident Landlord Scheme (NRLS).
By default, your UK letting agent (or the tenant, if there’s no agent and the rent is above a certain amount) must withhold basic-rate tax at 20% from your rent before you receive it.
You can avoid this upfront deduction by applying to HMRC using form NRL1 for approval to receive your rent gross, then pay the tax yourself through Self Assessment. Most experienced landlords do this to improve cash flow, but either way, you’ll usually still need to file a UK tax return. From there, a few more ownership-phase points matter.
A few more ownership-phase points:
Your rental profits are taxed at UK rates (20%, 40%, or 45%). Many non-residents, including British citizens, can still claim the UK personal allowance against this income, so check your situation.
Mortgage interest is no longer fully deductible. For individual landlords, you now only get a 20% tax credit, which increases the effective tax bill for higher-rate taxpayers. This change has affected buy-to-let calculations for everyone, including expats.
Since April 2026, Making Tax Digital rules apply to landlords with income above certain levels, increasing administrative requirements.
The tax on the way out: capital gains and a 60-day trap
When you sell, non-residents have had to pay UK capital gains tax on UK residential property since April 2015 (and on all UK property since April 2019). Gains are taxed at 18% or 24% for individuals, with the value usually reset to 2015 so you’re only taxed on the growth since then.
The main pitfall here is the process itself, which often catches people out. You must report the sale and pay any CGT within 60 days of completion. This is a tight deadline, separate from your normal tax return, and it applies even if you don’t usually file in the UK. If you miss it, you’ll face penalties. After that, one tax issue can still follow you regardless of where you live.
The tax you can't leave behind: inheritance tax
One thing that never changes when you move overseas: UK residential property is always subject to UK inheritance tax, no matter where you live or where you’re officially based, because it’s a UK asset.
Holding property through an offshore company, once a common way to avoid inheritance tax, no longer works. It’s the classic case of a ‘UK-situs asset that stays in the net wherever you live,’ as explained in our guide to UK inheritance tax for expats. For many expat property owners, this is the biggest long-term tax issue.
The currency angle
Finally, there’s a factor that’s easy to overlook until it causes problems. If your income is in dirhams, dollars, or euros but your mortgage, deposit, and running costs are in pounds, the exchange rate quietly changes the real cost of owning the property. That means the currency story runs through the whole investment, not just the monthly payment.
For bigger commitments like a deposit or ongoing mortgage payments, it’s worth planning for this risk instead of leaving it to chance. That’s what our articles on the cost of moving money and managing currency exposure cover.
For those in the Gulf, the dirham's peg to the US dollar means your currency risk is really a pound-versus-dollar story.
Are expat buy-to-let mortgages still worth it?
None of this means UK property is a bad investment for expats. For many, it’s still a solid, familiar long-term option.
But the reality is that the extra costs—a tougher, more expensive mortgage, higher stamp duty, tax on the rent, tax on the gain, inheritance tax, and currency risk—mean the numbers are very different from a resident buy-to-let. A property that seems profitable based on the headline rent can look quite different once you add up all six layers.
So the main takeaway is simple: look at the full picture, not just the mortgage and rent, and get advice from a specialist expat mortgage broker and a qualified UK tax adviser before you commit. Since your residence status affects so much of this, our guide to whether you’re still a UK tax resident is a helpful resource.
