How Does Mortgage Work in London for Overseas Investors?
Overseas investors can access mortgage financing in the UK, typically requiring a deposit between 25–40%.

Securing a mortgage as an overseas investor in the UK is entirely possible, though the process involves specific requirements that differ from domestic buyers. Understanding these nuances early in your investment journey can help you structure the purchase effectively and secure the most competitive terms available.
Most international buyers will need to provide a deposit of between 25% and 40% of the property value. The exact percentage depends on several factors including the lender, your country of residence, income verification methods and the property type. Buy-to-let mortgages for overseas investors typically require higher deposits than residential mortgages.
Key Points
- Limited lender options compared to UK residents
- Interest rates may vary — typically 0.5–1.5% higher
- Rental income can be considered for buy-to-let
- Deposit requirement: 25–40% for overseas buyers
Lender options for international applicants have expanded in recent years, though the field remains more limited than for UK residents. Specialist international banks, private banks and select UK high-street lenders offer products tailored to overseas buyers. Interest rates typically sit 0.5% to 1.5% above equivalent UK resident rates.
Income verification is a critical step. Lenders will assess your global income and may require translated and certified financial documents. Rental income from the target property can sometimes be factored into affordability calculations, particularly for buy-to-let applications where projected rental yields meet minimum coverage ratios.
