London Buy-to-Let: What Overseas Investors Should Research First

The Short Answer

Start with the full cost, not the price. Stamp duty, including any surcharge that applies to non-UK residents, legal fees, survey, lender costs and furnishing all sit on top of the purchase price. Then check the tenure and charges of the specific building, and who will let and manage the property. Rates and rules change, so confirm each one with the official source on the day.

We deliberately do not quote yields or rents for "London" as a whole. They vary widely by area and building, and a single figure would mislead. Use current listings and published data for the exact postcode, and note the date.

Build the Budget First

• Purchase taxes. Stamp Duty Land Tax applies in England, with higher rates for additional properties and a surcharge for some non-residents. Check the current rates on GOV.UK. See our worked buy-to-let budget example.
• Full cost of buying. Read the full cost of buying UK property from abroad.
• Exchange rate. If you convert from another currency, the rate on completion day affects your real cost. See GBP exchange rate risk.

Check Tenure and Charges

Many London flats are leasehold. The lease length, ground rent, service charge and any planned major works matter as much as the purchase price, because they reduce your net income and affect what a future buyer will pay.

• Ask how many years remain on the lease. A short lease is harder to sell and finance. See short leases explained.
• Ask for the service charge accounts and any notices about works. See Section 20 consultation.
• Check the ground rent terms. See ground rent for leasehold flats.

Understand Tenant Demand

Rental demand in London depends on the area, the type of home and the tenants it suits: young professionals, families, students or corporate tenants. Look at how long comparable homes take to let and at the rent they achieve in the same building or street. Use real listings and, where available, ONS or other published rental data, and record the date you looked.

Be sceptical of any yield quoted without the rent, the price, the costs and the date behind it.

Know a Landlord's Duties

• Energy performance and safety certificates are required for rented homes. See EPC rules for landlords and landlord safety certificates.
• Tenancy deposits must be protected. See tenancy deposit protection.
• Right to Rent checks apply to tenants in England. See Right to Rent checks.
• Some London boroughs run landlord licensing schemes. See landlord licensing in England.
• Tenancy law in England is changing under the Renters' Rights Act, so check the current position on GOV.UK before you let.

Line Up the Right People

• A conveyancing solicitor who has handled purchases for overseas clients. See choosing a conveyancing solicitor.
• A letting agent that is clear about fees, client money protection and what is included. See letting agents for overseas landlords.
• A tax adviser for the non-resident landlord rules and your home-country tax position.
• A mortgage broker if you plan to borrow. See UK mortgages for overseas buyers.
