Buy-to-Let Mortgages in Southwark

🏢 Investing in Rental Property Across SE1

Southwark has become one of central London’s most dynamic rental markets — with strong demand from professionals, students and corporate tenants around London Bridge, Bermondsey, Borough and Elephant & Castle. Whether you’re investing in a modern flat or a period conversion, choosing the right buy-to-let mortgage is crucial.

We support landlords across SE1 with tailored buy-to-let mortgage solutions, including personal ownership and limited company (SPV) structures.

🏡 What Is a Buy-to-Let Mortgage?

A buy-to-let mortgage is designed specifically for properties that will be rented out to tenants. Unlike residential mortgages, lending is usually based on the rental income the property can generate rather than just your personal income.

Lenders assess the projected rental yield to ensure it covers the mortgage repayments, typically at a higher “stress rate” than the actual interest you’ll pay.

💷 Deposit Requirements & Affordability

Most buy-to-let lenders require a minimum deposit of 20–25%, although some will consider 15% for strong applicants. The rental income must usually cover between 125% and 145% of the monthly mortgage payments, depending on whether you’re a basic-rate or higher-rate taxpayer.

Affordability is also stress-tested — often at an interest rate of around 5.5%+ — even if you’re securing a fixed-rate product at a lower rate.

🏢 Buying Through a Limited Company

Many investors in Southwark now purchase buy-to-let properties through a limited company (Special Purpose Vehicle – SPV). This can offer potential tax advantages, particularly for higher-rate taxpayers, as mortgage interest is fully deductible as a business expense.

We help you understand the pros and cons of buying via a company vs. personal name, and guide you through what lenders will require in each case. Mortgage rates, fees, and stress-testing differ between the two paths — but both are viable depending on your investment goals.

📊 Rental Yield & Return on Investment

Rental yields in SE1 vary widely — prime areas near the river often offer lower yields but strong long-term capital growth, while fringe regeneration zones can provide better short-term returns.

We help you understand what lenders look for in terms of rental coverage and how to structure borrowing for both yield-focused and capital-growth strategies.

🧾 Other Considerations for Landlords

✅ Energy Efficiency

Most buy-to-let properties must have a minimum EPC rating of E or above. New proposals may tighten this requirement in future. We’ll help you understand how this affects your lending options.

✅ Tenancy Structure

Most lenders prefer properties let on a standard Assured Shorthold Tenancy (AST). If you’re letting to students, multiple tenants (HMO), or via short-lets, different products and criteria apply.

✅ Landlord Experience

Some lenders favour experienced landlords, while others offer products for first-time investors. We’ll help position your application accordingly.
