British citizenship grants to US nationals increased by approximately 29% in the first half of 2026, according to newly reported analysis of Home Office figures. Separately, prime London buying agency Eccord says American clients are searching with budgets of £3 million to £30 million.
The citizenship analysis, attributed to Eccord and Schroders Wealth Management in The Luxury Property Forum’s 9 November report, records 3,911 grants between January and June, compared with 3,043 in the same period of 2025.
For a family considering a London purchase, the financing question can extend well beyond the deposit. The property will be priced in pounds, while earnings, investments, existing mortgages and business interests may remain principally American. Establishing how those resources support the acquisition is central to the borrowing decision.
American ties to Britain: the reported figures
Source: The Luxury Property Forum, 9 November 2026, reporting Eccord and Schroders Wealth Management analysis and Eccord’s client observations. Citizenship grants, property search budgets and completed purchases are different measures.
London searches range from family relocation to a part-time base
Eccord reports that Americans have represented approximately 40% of its prime central London home-search clients over the past two years. The agency describes families moving for work or education alongside purchasers seeking a London base, with some choosing to rent before buying.
The same report announced a New York discussion scheduled for 12 November involving Eccord, Schroders Wealth Management US and Boodle Hatfield, covering property, immigration and cross-border wealth. It was an advance announcement; it should not be read as a report of conclusions reached at that event.
Those different property objectives matter to a lender. A home occupied immediately, a residence used during school holidays and a property intended for letting require the purpose and occupancy to be established before suitable borrowing can be assessed.
Citizenship grants do not count new property buyers
The increase from 3,043 to 3,911 is 868 grants, or approximately 28.5%, rounded to 29%. It measures citizenship decisions, rather than applications, arrivals or house purchases. It does not establish how many recipients are wealthy, newly resident or looking for a London home.
The Home Office’s citizenship statistics distinguish naturalisation from registration. The routes reflect different circumstances, and a grant can follow an existing connection to Britain. Eccord’s client share is also specific to one agency; it cannot be used as the American share of the London housing market.
Property ownership and immigration status remain separate. Government citizenship guidance sets out eligibility routes according to personal circumstances. Buying a home does not itself confer British citizenship or permission to live in the UK.
A nationality-specific development within a divided prime market
Willow’s 13 November article, £5m-Plus London Sales Rise 13.6% as Prime Market Slows, examined October’s increase in higher-value transactions alongside a 17.5% decline across the wider prime market.
The American client observations add context to that discussion, but the datasets cannot be joined to explain the sales increase. The citizenship figures do not identify purchasers, and the transaction report does not establish that Americans drove October’s result.
A London purchase can leave the household finances largely in dollars
A prospective buyer may retain a US home and its mortgage, continue receiving American remuneration and fund school or family costs in both countries. The proposed UK mortgage therefore needs to be assessed alongside the commitments that remain after completion.
Residence, nationality and income currency are separate questions. A lender accepting dollar earnings may still restrict where borrowers can live or which immigration circumstances it accepts. A planned move can also change the employment arrangements on which an initial assessment was based.
For that reason, an early review should establish where each applicant lives now, whether employment will change, when the UK property will be occupied and which income will continue. A case based on the position before relocation may need revisiting if those facts change.
US earnings need to translate into sustainable sterling repayments
Salary, bonuses, partnership distributions and investment income should be explained separately. A substantial annual tax return does not necessarily show how much cash is received regularly, what is retained within a business or which payments are expected to recur.
The supporting records may include US tax returns, W-2 statements, K-1 schedules, payslips, company accounts and bank statements, according to the income and lender involved. The purpose is to connect declared earnings with accessible funds and the commitments those funds already support.
HSBC’s published foreign-currency criteria provide one example of the underwriting issue: accepted overseas income is converted to sterling and subject to a lender adjustment, often called a haircut, within affordability calculations. That is an illustration of lender treatment, not a universal formula or a recommendation of a particular bank.
Currency also matters after completion. If sterling strengthens against the dollar, the same sterling payment requires more dollars. A fixed mortgage rate does not fix that exchange rate. Deposit conversion and ongoing mortgage payments therefore need to be considered separately.
Substantial assets still need a clear route into the purchase
A buyer’s net worth may be spread across brokerage accounts, business holdings, existing property and trusts. The amount available for exchange and completion can be materially different from the headline asset total.
The funding plan should identify the deposit, purchase costs and reserves to be retained, then establish when each source becomes available. Funds from an investment sale, company distribution or family gift can require different supporting records. The transfer history should make their origin clear to the professionals handling the transaction.
A strong US credit history can support the wider picture, but it should not be assumed to substitute automatically for a lender’s UK requirements. The available route depends on how residence, credit evidence, income, deposit and property fit together. There is no single deposit percentage that applies to every American buyer.
Retaining investments requires a comparison of borrowing costs and risk
Some purchasers may prefer a mortgage to selling a substantial investment holding. That can preserve their existing market exposure, while adding interest costs and repayment obligations. The expected return on retained assets is uncertain and should not be treated as a guaranteed way to cover the borrowing.
Borrowing against an investment portfolio is a separate arrangement from a mortgage secured on the property. The SEC and FINRA’s investor guidance on securities-backed credit explains that falling collateral values can lead to demands for additional security or repayment, with securities potentially sold if the shortfall is not met.
Where a private bank proposes lending alongside an investment relationship, the whole arrangement needs examining: eligible assets, custody or management requirements, fees, security and access to cash. A large purchase price alone does not establish that this is the appropriate route.
Tax and ownership decisions need to reach both sides of the Atlantic
The IRS states that US citizens abroad generally remain subject to US tax on worldwide income, with reliefs and reporting requirements depending on their circumstances. Moving to Britain does not, by itself, bring American tax obligations to an end.
That makes coordination important before selling investments, distributing company funds or choosing how to own the property. A structure that appears convenient for UK borrowing may have different consequences in the United States. Ownership and the source of purchase money should be agreed with the relevant legal and tax advisers before the mortgage application relies on them.
Citizenship, permission to reside and tax residence should also be kept distinct. The timing of a move can affect the wider financial position even where the property purchase itself has not changed.
The useful starting point is the purchase plan
For an American household searching in London, the early questions are practical: how the home will be used, how much borrowing is required, where the deposit is held and which US earnings and commitments will continue. Renting first can provide time to settle those decisions, but it does not replace the need to assess future mortgage eligibility.
Willow can bring that information into a single financing review, compare suitable lender routes and coordinate the application with the buyer’s other advisers through to completion. The recent figures give a reason to examine this market closely; the finance still needs to fit the individual household, property and timetable.

Explore UK Property Finance for US BuyersFrequently asked questions
Does the 29% increase mean 29% more Americans bought UK homes?
No. It is the rounded increase in British citizenship grants to US nationals between the first halves of 2025 and 2026. The figures do not count property purchases. Eccord’s search budgets and client share describe its own business, not the whole London market.
Do American buyers need British citizenship to obtain a UK mortgage?
British citizenship is not a universal mortgage requirement. Lenders assess nationality, residence, immigration circumstances, income, deposit, credit evidence and property use. Buying a property does not itself grant citizenship or permission to live in the UK.
Can US dollar earnings support a sterling mortgage?
Potentially. Acceptance depends on the lender and the applicant’s circumstances. Lenders can use different conversion methods and adjustments when assessing dollar income. Exchange-rate changes can also alter the dollar cost of sterling payments after completion.
Can I keep my US investments when buying a London home?
Potentially, if suitable borrowing and sufficient purchase funds are available. A property mortgage and a loan secured on investments involve different security and risks. Retaining investments leaves market exposure in place, while investment-backed borrowing can require additional collateral or repayment if values fall.
What should I prepare for a US-buyer mortgage assessment?
Provide the intended property use and purchase budget, current and planned residence, income records, US liabilities, credit information and details of the deposit and its source. Explain any employment changes, company or trust involvement and assets you wish to retain. The exact documents depend on the lender and transaction.
