UK Mortgages for Expats & Foreign Nationals Living in the USA
A UK mortgage for US expats is possible, and more specific than most applicants expect – the gap between a standard broker and one who actually knows this market shows up fast.
US dollar income, FATCA obligations, limited UK credit history, and lenders who quietly exclude US-based applicants without making that clear upfront – these are not edge cases. They are what most applications from the US run into. Getting to the right lender before any of that becomes a problem is where the process starts. If you want to check where you stand first, our guide on whether expats can get a UK mortgage sets out the eligibility basics.
At Expat Mortgages UK we work exclusively with expats and foreign nationals. We know which lenders are comfortable with US-based applicants, how USD income is assessed, and how to structure an application that accounts for cross-border tax complexity from day one.
UK Mortgage Options for US-Based Applicants
Three routes. Each one works differently from the US than it does for a UK resident – and knowing which one fits your situation before you approach anyone saves a lot of time.
Buy-to-let mortgages for US property investors is where most US expats start. Lenders care more about what the property earns than what you do – so USD income and a thin UK credit file matter less than they would on a residential application. The catch is FATCA. The moment rental income starts arriving in a UK account, US reporting obligations kick in. Not a dealbreaker – but something to have sorted before completion, not after.
Residential mortgages are for those who plan to come back. The lender pool is smaller and they want to see a real connection to the UK – an address history, a return date, family ties, something that makes the plan credible. Vague intentions do not carry weight with underwriters.
Remortgaging covers anyone who already owns UK property and wants to move it onto a better deal, release equity, or change the mortgage type entirely. The whole thing can be handled remotely – no flight required.

What Lenders Need for a UK Mortgage for US Expats
The requirements are not dramatically different from any other expat application – US-based applicants do hit specific friction points though.
Income Evidence
This needs to be thorough. Payslips, tax returns, employer confirmation – lenders want to see stability, not a single strong number. USD income is accepted by specialist lenders but converted conservatively, so the figure they work from is always lower than what lands in your account. How overseas earnings are assessed and discounted is set out in full in our guide to expat mortgage income requirements. Factor that gap in early – it affects what is realistic before you make an offer.
Self-employed and 1099 contractor income needs a slightly different documentation pack than a salaried applicant – typically two to three years of Form 1040 filings alongside Schedule C, a CPA reference confirming the business is still trading, and recent business bank statements. Lenders generally average income across the two most recent years rather than taking the latest, strongest year on its own, so a recent income jump doesn’t automatically translate into extra borrowing power the way it might feel like it should. Worth knowing early if you’re a contractor in one of the tech-heavy cities covered further down this page – it’s the single biggest documentation difference between a straightforward salaried case and a self-employed one.
UK Credit History
This is the most common sticking point. If you have been in the US for more than a couple of years with no active UK accounts, your credit file is effectively dormant. Some lenders will work with US credit reports and alternative financial evidence. Others will not. Knowing which camp a lender falls into before applying is the difference between a clean first application and a decline that sits on your file. Our guide to building UK credit history as a US expat covers exactly what specialist lenders look for when your file is thin or empty.
Deposit
Deposit requirements sit at a minimum of 25% for buy-to-let and typically 10-20% for residential. A larger deposit unlocks more lenders and takes pressure off everything else – particularly useful where income or credit history is more complex. Our Expat Mortgage Calculator UK gives a quick sense of loan size and deposit before you approach anyone.
Gifted deposits are accepted by most lenders, but the gift needs a signed letter confirming it’s non-repayable with no strings attached, plus a paper trail showing exactly where the money came from. A US-based parent or relative gifting funds should expect the same scrutiny on money leaving a US account as on any other part of the application.
Visa Status
This matters to some lenders more than others. Indefinite Leave to Remain is the cleanest position. A valid work visa with at least two to three years left on it usually works – H-1B, L-1 and O-1 holders are the most common profile we see, and TN visa holders (Canadian and Mexican professionals working in the US) come up regularly too. Green card holders sit close to Indefinite Leave to Remain in how lenders view stability, since there’s no expiry date creating urgency. Dual UK-US citizens tend to have the easiest time of it on the visa side, though FATCA still applies in full – it’s triggered by US citizenship and tax residency, not by which passport you’re travelling on. Short-term or uncertain visa arrangements narrow the pool significantly, worth checking before you commit to legal fees.
Two Worked Examples: How the Numbers Play Out
Requirements are one thing. Seeing how a UK mortgage for US expats translates into an actual borrowing figure is another. These two illustrations show how a US-based application is assessed in practice – one purchase, one remortgage.
Worked Example 1 – Buying a UK home while working in the US
Take a British national on a USD 240,000 salary at a California tech employer, planning to buy a £750,000 London flat as the base she returns to. With a 25 percent deposit of £187,500, her borrowing requirement is £562,500.
What changes for a dollar-paid applicant is the income a lender actually works from. A currency haircut discounts foreign earnings to guard against exchange-rate swings, and a 20 percent discount is a fair working figure here. That drops her assessed income from roughly £190,000, converted at an indicative rate, to around £152,000. Even discounted, and stretched over an example income multiple of 4.75 times, that supports borrowing near £722,000 – well above the £562,500 she needs.
Two things drive the outcome. The headline dollar salary is never the amount lent against, so every calculation begins from the discounted figure rather than the payslip. Expat pricing also runs higher than the rates shown to UK-resident borrowers, so her monthly cost needs modelling on expat terms rather than domestic ones. Figures shown are for illustration only and do not constitute a quote. Because she stays non-UK-resident right through to completion, and this is her only UK property, the non-resident stamp duty surcharge applies on its own – the additional-dwelling surcharge doesn’t come into it. Worked through in full below.
Worked Example 2 – Remortgaging a let UK property from the US
Picture a green card holder settled in Boston who let out his former UK home after relocating. The property is valued at £480,000 against a £260,000 balance, his fixed term is expiring, and his income splits between a US dollar salary and £1,900 a month in sterling rent.
Borrowing £260,000 on a £480,000 valuation works out at roughly 54 percent loan-to-value, which sits comfortably for expat buy-to-let. A case built this way rests on the rent rather than the salary, so the lender applies a rental stress test, illustrated here at 145 percent – the rent must cover the mortgage at a notional stressed rate with headroom to spare. At this LTV and rent level, the numbers have room to breathe. The rent carries a further advantage: no haircut reduces it, since sterling needs no conversion. His dollar salary matters only where the rent by itself does not reach far enough and top-slicing steps in, with the haircut then confined to that portion.
For an expat in this spot, a tenanted UK property is frequently easier to refinance from overseas than expected, since the sterling rent shoulders most of the assessment. These figures are illustrative and do not constitute a quote.
Stamp Duty for US-Based Buyers: The Non-Resident Surcharge
Anyone buying UK property without UK tax residency pays an extra 2% surcharge on top of standard stamp duty rates. Residency comes down to a day count: spend fewer than 183 days in the UK in the 12 months before completion and you’re treated as non-resident, which covers most US-based buyers at the point of purchase.
A second surcharge, 5% on top, kicks in when the purchase is an additional property – a buy-to-let, a second home, or anything bought while you still own another. Non-resident and buying a second property at the same time means 7% stacked on top of the standard bands.
Run that against Worked Example 1’s £750,000 purchase: treating it as her only property, standard SDLT works out to £27,500. Add the 2% non-resident surcharge (£15,000) and the completion bill comes to £42,500. She can get that non-resident portion back if she becomes UK tax resident within 12 months of completing – 183+ days present – with two years allowed to file the claim. One caveat worth flagging: this figure assumes no first-time buyer relief. If she’s never owned property anywhere, a separate relief could shrink the standard portion, so check current HMRC thresholds with a solicitor at the time rather than guess either way.
Worked Example 2 doesn’t get a stamp duty figure because there’s nothing to tax – remortgaging isn’t a purchase. Stamp duty only fires on a change of ownership, so refinancing a UK buy-to-let from the US carries no SDLT bill at all.
Funding a Deposit from a 401(k) or IRA
Quite a few US-based buyers plan to pull some or all of their deposit out of a 401(k) or IRA instead of a regular savings account. Lenders in the UK are fine with this in principle – the money just has to arrive cleanly and be fully accounted for.
Pull money out before you turn 59½ and the IRS takes a 10% penalty off the top, on top of ordinary income tax on whatever you withdraw. So whatever lands in a UK completion account ends up noticeably smaller than the balance sitting on the statement – plan around that net number, not the one you started with. Borrowing against a 401(k) instead, where the plan allows it, sidesteps that penalty, but it adds a second monthly repayment back in the US, and a UK lender will fold that into the affordability sums alongside the new mortgage.
Either way, expect UK conveyancers and lenders to want the whole trail documented: the statement showing money leaving the retirement account, confirmation it left a US bank account, and the transfer bringing it into sterling. Missing a link in that chain is one of the more common reasons a source-of-funds check runs long – worth having it all together before an offer’s accepted, not scrambling for it afterwards.
Tax and FATCA Considerations for US-Based UK Property Owners
Living in the US does not remove UK tax obligations on UK property. A UK mortgage for US expats also brings a tax layer that most expat mortgage guides skip entirely.
Rental Income
Rental income from a UK property is taxable in the UK regardless of where you live. Register under the Non-Resident Landlord Scheme before the tenancy starts or the letting agent withholds tax at source. The same income also needs reporting on your US tax return – but the US-UK Tax Treaty means you can usually claim UK tax paid as a foreign tax credit against your US liability.
Capital Gains
Capital gains on a UK property sale are taxable in the UK and must be reported to HMRC within 60 days of completion. The US may tax the gain too, but foreign tax credits or exclusions typically apply. Take advice before selling – the interaction between the two systems catches people out.
FATCA
FATCA is the piece most US-based applicants underestimate. If you hold a UK bank account for rental income, a UK mortgage, or UK financial assets above the reporting threshold, annual disclosure to the IRS via Form 8938 is required. UK lenders must identify US account holders and report certain information to HMRC, who pass it on to the IRS. This is why many lenders ask for a W-9 form during the application. It will not stop an application – it just needs to be in order before you apply, not discovered afterwards.
Tax advice from a specialist in US-UK cross-border tax is strongly recommended before committing to a purchase.
Why US-Based Applicants Work With Expat Mortgages UK
Most UK mortgage brokers are not built to arrange a UK mortgage for US expats. Their lender relationships, documentation processes and compliance setup are designed around UK residents – not someone managing an application from New York or Austin in a different time zone, earning in dollars, and navigating FATCA obligations on top of a standard mortgage process.
We work exclusively with expat mortgage applicants and foreign nationals. That means we know which lenders are genuinely comfortable with US-based applications – not just expat applications in general – and which ones will quietly apply criteria that excludes most US applicants without making that clear upfront.
Every client gets a dedicated mortgage advisor and a dedicated case manager. Both are reachable directly by phone and email throughout. The WiiN portal gives you a live view of your application at any hour – useful when you are several time zones behind the UK and cannot wait for office hours to find out where things stand.
Before anything is submitted, we work through your income structure, your US tax position, and which lenders currently fit your profile. That conversation costs nothing. Getting the wrong lender first does.
FAQs: UK Mortgages for US Residents
Can British expats living in the US get a UK mortgage?
Yes – but not through a high street bank. Specialist lenders understand US dollar income, limited UK credit history and FATCA obligations.
Getting to the right one before applying is what determines the outcome.
How does USD income affect a UK mortgage application?
Most specialist lenders accept it but apply a conservative currency conversion.
The income figure they assess you on will be lower than what you earn. Factor that gap in before setting a budget.
Do I need a UK credit history to apply?
Not always. Some lenders will work with US credit reports and alternative financial documentation. Others require UK credit history.
A dormant UK file is one of the most common friction points for US-based applicants.
How much deposit do I need?
Buy-to-let typically requires 25% minimum. Residential mortgages usually need 10-20%.
A larger deposit opens more lender options and reduces scrutiny on income and credit complexity.
Will FATCA stop me getting a UK mortgage?
No – but it will slow things down if it is not in order. Some lenders avoid US applicants entirely because of the reporting burden. Others handle it regularly.
Getting to the right lender first is what matters.
Are there visa restrictions for US residents applying for a UK mortgage?
Some lenders require Indefinite Leave to Remain or a work visa with at least two to three years remaining. Buy-to-let generally has fewer restrictions than residential.
Worth checking before committing to legal fees.
Can I manage the whole process without travelling to the UK?
Yes. Documents are shared online, the property valuation happens in the UK, and solicitors handle the legal work there.
Most US-based clients complete without visiting the UK at any point.
Will I pay stamp duty as a non-UK resident buying from the US?
Most likely, yes: a 2% non-resident surcharge applies on top of standard rates, plus a further 5% if it’s a second property or buy-to-let.
That non-resident portion is reclaimable if you become UK tax resident within 12 months of completing, with two years allowed to make the claim.
Can I use money from a 401(k) or IRA for my UK deposit?
Yes – a number of our US-based clients fund some or all of their deposit this way.
Just budget from the amount left after any early-withdrawal penalty and tax, not the account balance, and keep the withdrawal and transfer documentation together for the lender’s source-of-funds check.
Will I pay UK tax if I sell my property while I'm still living in the US?
Yes – UK capital gains tax applies on the sale regardless of where you live, and it must be reported to HMRC within 60 days of completion.
The US may tax the same gain too, but the US-UK Tax Treaty usually lets you claim the UK tax paid as a credit against your US liability.
UK Mortgages for British Expats Across the US
We work with UK expats and foreign nationals based across the United States. The application process is the same wherever you are – remote, structured, and handled without returning to the UK.
New York hosts the main British Consulate-General for the US, and its concentration of finance and law professionals gives lenders a well-understood income and employment profile to work from. Los Angeles has its own consulate too, but more of its applicants are entertainment-industry or tech-adjacent self-employed earners, which takes more careful lender matching than a standard salaried case. Austin has no consulate of its own – the nearest is Houston – but Texas’s lack of state income tax has pulled in a fast-growing British tech contractor community around the city’s “Silicon Hills” cluster. Chicago and Boston both have a British Consulate-General and tend to draw professionals on straightforward salaried contracts – Boston’s cluster leans academic and biotech, built around its university and hospital sector, which gives lenders a particularly clean income picture. Seattle, like Austin, has no consulate nearby – the closest is San Francisco – but Washington State’s lack of income tax and its handful of major tech employers produce a similarly contractor-heavy income profile to Austin’s. Miami has a British Consulate-General and, paired with Florida’s no-income-tax status, has built a strong international investor base where buy-to-let is the most common way in – if that’s your angle, our guide on whether US expats should invest in UK buy-to-let weighs up the pros, cons and best locations.
The key variables are not where in the US you live – they are your income structure, your UK credit position, and whether the lender you approach is genuinely set up to handle a US-based application. Those factors matter far more than your zip code.
Start With a Conversation Before Anything Goes In
The most common mistake US expats make when arranging a UK mortgage is approaching a lender – or a broker who does not handle US cases specifically – before understanding how that lender will actually assess the application. A decline at that stage costs time, leaves a mark on the credit file, and makes the next step harder.
We work with US-based expats and foreign nationals from initial conversation through to completion. Before anything is submitted, we want to understand your income structure, your US tax position, and which lenders are currently the right fit for your profile. That conversation costs nothing and changes the outcome significantly.
If you are living in the US and thinking about UK property – whether a first purchase, an addition to a portfolio, or a remortgage on something you already own – speak to us before you speak to anyone else.
Expat Mortgages UK is a specialist broker directly authorised and regulated by the Financial Conduct Authority. We work exclusively with expats and foreign nationals buying UK property with overseas income. Your home may be repossessed if you do not keep up repayments on your mortgage.
