Buying Property in the UK as an American: Process, Taxes, and Financing

Americans can buy property in the UK with no legal restrictions. There is no citizenship or residency requirement, and you can own a home outright whether you live in Britain or are still in the U.S. The differences are financial, not legal: as a non-resident, you pay a 2% Stamp Duty surcharge on top of the standard rates, a further 5% if you already own a home anywhere in the world, and you will usually need a larger deposit (25% to 40%) through a specialist expat mortgage.

A few things to know before you start:

There is no ban on foreign buyers. Your nationality does not stop you from owning UK property.
Stamp Duty is higher for non-residents. Expect the 2% non-resident surcharge, and often the 5% additional-property surcharge too.
Your U.S. home counts against you. Owning property anywhere in the world can trigger the 5% surcharge on your UK purchase.
Buying is not a U.S. taxable event, but the mortgage can be. Paying off a foreign-currency mortgage can create a separate U.S. tax bill.

This guide walks you through the buying process, Stamp Duty surcharges, financing from the U.S., and U.S. tax considerations that catch American buyers off guard.

Americans Face No Legal Barrier to Buying UK Property

The UK places no restrictions on foreign nationals owning property. You do not need to be a citizen, a resident, or a visa holder to buy, and you can purchase as an individual from abroad. Most UK homes are sold either freehold (you own the building and the land) or leasehold (you own the right to live there for a fixed term, common with flats), and both are open to American buyers.

What you do not get as a non-resident is access to the cheapest mortgages or the lowest Stamp Duty rates. Those are the practical hurdles, and they are the rest of this guide. If a move is part of the plan, our guide to moving to the UK from the USA covers the wider picture.

How the UK Buying Process Works

The UK process differs from a U.S. closing, and the timeline usually runs eight to twelve weeks from offer to completion.

Search and offer: Listings are on Rightmove and Zoopla, or through local estate agents. Offers are made through the agent and are not legally binding at this stage.
Instruct a solicitor or conveyancer: They handle the legal work, searches, and contracts. A non-resident buyer is normal for them, though they will run extra identity and source-of-funds checks.
Survey and searches: A surveyor checks the property’s condition, and local authority searches flag any planning or boundary issues.
Exchange of contracts: This is the point of no return. You pay a deposit (typically 10%), and both sides are now legally committed. A completion date is set.
Completion: The balance is transferred, you get the keys, and your solicitor files the Stamp Duty return and pays the tax within 14 days.

Stamp Duty and the Surcharges Americans Pay

Stamp Duty Land Tax (SDLT) applies to property purchases in England and Northern Ireland. (Scotland and Wales run their own equivalents.) The standard residential rates, in place since 1 April 2025, are tiered, and you can confirm them on the government’s SDLT residential rates page.

Portion of price	Standard rate
Up to £125,000	0%
£125,001 to £250,000	2%
£250,001 to £925,000	5%
£925,001 to £1.5 million	10%
Above £1.5 million	12%

Two surcharges stack on top for many American buyers:

The 2% non-resident surcharge. If you were not in the UK for at least 183 days in the 12 months before you buy, you pay an extra 2% on the full price, set out in the government’s non-resident SDLT rates. You can reclaim it if you become UK resident within 12 months of the purchase.
The 5% additional-property surcharge. If you already own a home anywhere in the world, including your house back in the U.S., the UK purchase is an “additional” property and carries an extra 5% on the full price.

A Real-World Example

Sarah, still living in the U.S. and keeping her American home, buys a £500,000 flat in London. Her Stamp Duty stacks up like this:

Component	Amount
Standard SDLT on £500,000	£15,000
Additional property surcharge (5%)	£25,000
Non-resident surcharge (2%)	£10,000
Total Stamp Duty	£50,000

That is an effective 10% of the purchase price, far above what a UK resident first-time buyer would pay. If the London flat were her only home worldwide, she would skip the 5% surcharge and pay £25,000.

Financing a UK Property From the U.S.

You can get a UK mortgage as an American, but you will use a specialist expat or non-resident lender rather than a typical high-street deal.

Expect:

A larger deposit, usually 25% to 40% of the price.
A narrower set of lenders, since not every bank lends to non-residents or accepts U.S. income.
Documentation in U.S. dollars, which specialist lenders handle routinely, recognizing the dollar as a strong currency and working from U.S. tax returns and credit history.
Higher rates than a comparable UK-resident mortgage.

Many American buyers pay cash or make a large down payment to widen their options. Whatever route you take, the currency of your mortgage matters for U.S. tax, which is the next point.

What U.S. Taxes Apply When You Buy and Own

Buying a UK home is not itself a U.S. taxable event, and you do not report the property on the FBAR or Form 8938, because directly held real estate is not a financial account.

Three U.S. Tax Issues That Affect Your Return

Owning a UK home does touch your U.S. return in three ways:

The foreign-mortgage currency trap: the one that surprises people. The IRS treats your GBP mortgage as separate from the house. If the dollar strengthens against the pound between the day you borrow and the day you pay off or refinance, you can owe U.S. tax on a phantom currency “gain” under Section 988, taxed at ordinary rates, and the home-sale exclusion does not shelter it. We cover the mechanics in our answer on the Section 988 currency gain on foreign property.
Rental income, if you let it out: Rent is taxable in both countries, with the Foreign Tax Credit preventing double taxation. The details are in our guide to UK rental income for American landlords.
Capital gains when you sell: A future sale is taxable in the U.S. and may face UK Capital Gains Tax too, with the FTC and the Section 121 home-sale exclusion in play. That is its own topic, covered in our guide to Capital Gains Tax on UK property.

Owning a UK home can also pull your worldwide estate into UK Inheritance Tax once you have lived in Britain long enough, as explained in our guide to UK Inheritance Tax for Americans.

Frequently Asked Questions

Can Americans buy property in the UK?

Yes. There is no legal restriction on Americans or any foreign national owning UK property, whether you live in Britain or the U.S. The hurdles are financial: a higher Stamp Duty bill and a larger mortgage deposit, not a ban.

Do Americans pay extra Stamp Duty in the UK?

Usually, yes. Non-residents pay a 2% surcharge on top of the standard rates, and if you already own a home anywhere in the world, including in the U.S., a further 5% additional-property surcharge applies. The 2% non-resident surcharge is refundable if you become a UK resident within 12 months.

Can I get a UK mortgage as a U.S. citizen?

Yes, through a specialist expat or non-resident lender. Expect a deposit of 25% to 40%, a smaller pool of lenders, and slightly higher rates. These lenders are set up to verify U.S. income, tax returns, and credit history.

Is buying a UK house taxable in the U.S.?

No. The purchase itself is not a U.S. taxable event, and you do not report the property on the FBAR or Form 8938. U.S. tax can arise later, from rental income, a future sale, and the currency gain on paying off a pound mortgage.

Do I have to report my UK property to the IRS?

The property itself is not reported on the FBAR or Form 8938, because real estate held in your own name is not a financial account. You do report any rental income, any gain on sale, and any Section 988 currency gain on the mortgage. A UK bank account you open for the purchase is separately reportable if your accounts cross the thresholds.
