Buy-to-Let Mortgage Brokers in West London
Whether you are purchasing your first rental property or growing an existing portfolio, we find the buy-to-let mortgage that works hardest for your investment.
Introduction
What Is a Standard Buy-to-Let Mortgage?
A buy-to-let (BTL) mortgage is a specialist product designed for properties purchased with the intention of renting them out, rather than living in them as a primary residence. They are assessed and priced differently from residential mortgages — with lenders typically placing significant emphasis on the expected rental income from the property, rather than purely the borrower's personal income.
West London remains one of the most resilient and high-demand rental markets in the UK. Areas such as Ealing, Hammersmith, Chiswick, and Brentford consistently attract young professionals, families, and international tenants, making rental yields attractive and void periods relatively short.
As an independent mortgage intermediary, West London Property & Let compares buy-to-let products across our full lender panel — from competitive high street rates to specialist products for more complex scenarios — ensuring your investment is financed in the most effective way possible.
Who is it for?
Is a Standard BTL Mortgage Right for You?
A standard buy-to-let mortgage is typically suited to landlords who:
- Are purchasing a single rental property (not via a limited company)
- Have a deposit of at least 20–25% of the purchase price
- Expect rental income to cover at least 125–145% of the monthly mortgage payment (the lender's rental coverage requirement)
- Have a personal income of at least £25,000 (required by some lenders)
- Are not planning to live in the property at any point
- Hold four or fewer mortgaged buy-to-let properties (five or more triggers 'portfolio landlord' criteria)

Frequently Asked Questions
How much deposit do I need for a buy-to-let mortgage?
Most BTL lenders require a minimum deposit of 25%, though some products are available at 20% LTV. A larger deposit will unlock better rates and lower your monthly outgoings.
How is rental income assessed?
Lenders calculate whether the expected rent covers a stressed version of the monthly mortgage payment — typically 125–145% of the interest-only cost at a notional stress rate of 5–5.5%. We will calculate this for any property you are considering.
Can I use a BTL mortgage for a flat above a commercial property?
Some lenders will consider this; others will not. We can identify which lenders will accept the property type in question.
What is an interest-only BTL mortgage?
Most BTL mortgages are offered on an interest-only basis, meaning monthly payments cover only the interest charge. The capital balance is repaid at the end of the term — usually through sale of the property.
Do I need to be an existing homeowner to get a BTL mortgage?
Not always, but many lenders do require it. We work with lenders who will consider 'first-time landlords' who do not currently own their own home.
