A buyer in Dubai or Riyadh can borrow against a London rental flat, and many do, though not from the high-street lender they would use if they lived in Kensington. A smaller group of banks and building societies offers buy-to-let mortgages for non-residents, on stricter terms, and the loan is sized by the rent rather than by the buyer’s salary. That stress test, not the deposit, is what usually limits how much a prime London flat will borrow.

Buy-to-let mortgages for non-residents: deposits, rates, lenders and the stress test
Who offers buy-to-let mortgages to non-UK residents
A non-resident in the Gulf can get a buy-to-let mortgage through a broker from international banks, Channel Islands specialists or a few UK building societies. Expect a deposit of 25 to 40 per cent, a rate of roughly 5 to 6 per cent on a two or five year fix, an arrangement fee of 1 to 2 per cent, and six to ten weeks to offer. The catch is the stress test: rent must cover interest at a stressed rate by 125 to 145 per cent, so low-yield prime flats borrow less than their price suggests.
Three kinds of lender. The international arms of large banks, which lend to their own expatriate and offshore customers, often with a minimum income and a relationship requirement. Specialist lenders based in the Channel Islands and the Isle of Man, which exist to serve buyers abroad and understand a Gulf payslip. And a handful of UK building societies that accept non-resident applications through a mortgage broker, usually from a list of approved countries that includes the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain and Oman. The Islamic banks sit alongside these with purchase plans.
Why a specialist broker is the route to non-resident lenders
No lender advertises these terms to the public; a broker who places non-resident loans every week knows which lender takes which case, and that is the route we use.
Deposit needed for a non-resident buy-to-let mortgage
Expect to put in 25 to 40 per cent of the price, with 35 to 40 per cent the usual ask for a buyer with no UK footprint and 25 per cent available to a customer the bank already knows. The deposit must come from the buyer’s own verified funds; the anti-money-laundering checks in our separate guide apply in full and the lender’s are the strictest. Stamp duty, legal fees and the lender’s own fees are paid on top, from cash.
Non-resident buy-to-let mortgage rates and arrangement fees
In the autumn of 2026 a non-resident buy-to-let loan at 60 to 65 per cent of the price is priced at roughly 5 to 6 per cent on a two or five year fix, about half a point above the rate a UK resident would pay for the same loan, with an arrangement fee of 1 to 2 per cent of the loan added to it.
Most loans are interest-only, with the capital repaid when the property is sold. Valuation fees, the lender’s legal costs and a broker fee come to a few thousand pounds more. Rates move with the Bank of England and are quoted on the day; the figures here are for scale.
The rental stress test for non-resident buy-to-let mortgages
The loan is sized by the rent. The lender takes the rent its own valuer says the flat will achieve, and requires it to cover the monthly interest, calculated at a stressed rate above the actual one, by a margin of 125 to 145 per cent.
Stress test worked example on a 3,500 pound monthly rent
On a flat valued to let at 3,500 pounds a month, a lender stressing at 6.5 per cent with a 135 per cent cover requires interest of no more than about 2,590 pounds a month, which supports a loan of roughly 480,000 pounds. If the flat costs 1,000,000 pounds, the test, not the deposit rule, is what limits the loan to 48 per cent.
Why rental yield decides how much you can borrow
This is why prime London flats, with their low yields, support less borrowing than their price suggests, and why a regional flat at a 6 per cent yield borrows more easily. A buyer with substantial other income can sometimes top up a shortfall with that income, but not every lender allows it for non-residents.
Documents lenders ask for from non-resident borrowers
The documents a non-resident lender will ask for before it issues an offer:
- Identity and funds: passport and ID, proof of address, and six months of bank statements for the account the deposit comes from.
- Proof of income: three to six months of payslips and an employer letter, or two years of audited accounts for a business owner, with translations if needed. Many lenders set a minimum income, commonly 50,000 to 75,000 pounds a year equivalent.
- A credit footprint: non-residents rarely have a UK credit file; the lender substitutes a home-country credit report or a banker’s reference.
- Other property and borrowing: details of other property and borrowing anywhere in the world.
- The rental figure: the tenancy, or the valuer’s rental figure, for the stress test.
How long a non-resident buy-to-let mortgage takes
Six to ten weeks from application to offer, longer than a resident’s four, because the documents cross borders and the underwriter asks more questions. A decision in principle can be had in days and should be obtained before the search starts, so that an offer on a flat is made knowing the loan is there. The mortgage offer must be in hand before exchange of contracts, and the completion date is then set with the lender’s drawdown in mind. Our guide to buying without travelling sets the loan inside the overall timetable.
Borrowing through a company for non-resident buy-to-let
A company that holds rental property can deduct the whole of its finance cost against rent, where an individual gets only a 20 per cent credit, and most of the lenders above offer company buy-to-let loans at a slightly higher rate with the directors’ personal guarantees. For a single flat the extra administration outweighs the saving; for a portfolio built with borrowing it is usually the right structure, and our guide on holding through a company sets out the full comparison including the annual tax on enveloped dwellings, which is relieved for a genuine letting business.
