UK mortgages for overseas and expat investors.

Yes. Three groups of lenders serve overseas buyers:

• International banks with UK operations, which lend to clients in their own network abroad.
• Specialist buy-to-let lenders that accept non-resident and expat applicants, often through brokers only.
• Private banks, for larger loans and clients with significant assets under management.

Eligibility depends on your nationality, country of residence, income currency and the property. Some lenders accept applicants from the Gulf, Hong Kong and Singapore readily and decline others. A specialist broker narrows this down before you apply.

Typically 25–40% of the price. HSBC, for example, sets a minimum deposit of 25%, with more required on the largest loans, and a minimum income of £50,000 for non-resident buy-to-let lending (HSBC criteria, checked October 2026). Other lenders set their own thresholds.

On a £250,000 apartment:

Stamp duty and fees cannot be borrowed, so the cash needed is the deposit plus £20,000 stamp duty plus legal and lender fees. See the costs and taxes guide for the full list.

Buy-to-let lending rests on the rent, not just your salary. Lenders apply an interest coverage test: the expected rent must exceed the mortgage interest by a set margin, calculated at a notional stress rate higher than the rate you will actually pay. If the rent does not pass, the lender cuts the loan and you put in a larger deposit.

The margin and stress rate vary by lender and by borrower. Higher-rate taxpayers and individual borrowers are usually tested more strictly than companies, because tax takes a larger share of their rent. Longer fixed rates can attract a lower stress rate.

Lenders also weigh:

• Your personal income and assets, often with a minimum income.
• Your age and the term, since the loan must be repayable within the lender's age limits.
• The property. Some lenders restrict very small studios, apartments above commercial premises or blocks with unresolved building safety issues.
• Your experience as a landlord, which helps but is rarely essential.

Your income and the mortgage are in different currencies, and both lenders and you need to plan for that.

• Lenders discount foreign income. Many apply a haircut to income in another currency, or accept only certain currencies. Income in major currencies, including the Gulf currencies pegged to the US dollar, is generally accepted by lenders that specialise in overseas borrowers.
• The rent is in sterling. Rent pays the sterling mortgage directly, which matches the currencies for the monthly payments. The mismatch is in your deposit, any shortfall you fund and the value of your equity in your own currency.
• Currency risk works both ways. If sterling weakens after you buy, your apartment and your rent are worth less in your home currency; if it strengthens, they are worth more. Fix the rate for your deposit and completion funds with a forward contract if you want certainty.

Some private and international banks lend in other currencies against UK property. That removes one mismatch and creates another: the loan balance in sterling terms moves with the exchange rate.

Yes. British nationals working abroad are among the best-served overseas borrowers, particularly those employed by large companies or in the Gulf and Asia. The process is the same as for any non-resident; holding a UK passport widens the lender choice but does not remove the stress test or the deposit requirement. Your stamp duty position depends on where you have spent your time, not your passport.

Investors building a portfolio often buy through a UK special purpose vehicle (SPV), a limited company set up only to hold property. Mortgage interest is a deductible cost for a company, whereas individuals receive a credit at the basic rate. From April 2027 that credit is 22% while property income is taxed at up to 47% (Autumn Budget 2025), so the gap matters more for higher-rate taxpayers.

Against that, fewer lenders offer SPV loans to non-resident directors, almost all require personal guarantees, and profit drawn from the company is taxed again. Company purchases also pay the higher stamp duty rates. Decide on the structure before you exchange: moving a property into a company later is treated as a new purchase.

This is where overseas buyers most often go wrong.

1. Pay the deposit in cash. Lenders do not lend on a building that does not yet exist. The exchange deposit, typically 10%, comes from your own funds.
2. Get an agreement in principle early. Ask a broker to confirm you are lendable and on what terms before you exchange, so you know the completion balance is achievable.
3. Apply near completion. Mortgage offers are valid for a limited period, typically months rather than years. If the building takes longer to complete than the offer lasts, the offer lapses. Apply when the completion date is close enough to fall inside the offer period.
4. Expect a valuation at completion. The lender values the finished apartment against the market at that time. If it values below the price, you fund the gap.
5. Keep a cash buffer. Rates, criteria and valuations can all move during a long build.

Cash buyers complete faster, avoid valuation risk and keep every pound of rent. Their yield equals the net yield on the property. Borrowing adds a return on your own money if the rent after costs exceeds the interest, and reduces it if it does not. Many overseas investors buy in cash, let the apartment, then refinance once a tenant and a track record are in place.

• Refinancing. Your rate at the end of a fixed period may be higher than the rate today.
• Currency. Equity and income in your home currency move with sterling.
• Valuation. A down-valuation at completion requires more cash.
• Rule changes. Tax on rent rises in April 2027; lender stress tests change with rates.
