This guide provides a detailed comparison between Buy-to-Let mortgages and bridging loans, outlining their key differences, benefits, and ideal use cases.
What is a Buy-to-Let Mortgage?
Key Features of a BTL Mortgage
- Loan Term: 5 to 30 years
- Interest Rates: Lower than bridging loans (typically 4-6% as of 2024)
- Repayment Type: Interest-only or repayment
- Deposit Requirement: 25%-40% (can be lower with specialist lenders)
- Lender Requirements: Based on rental income and affordability
When to Use a BTL Mortgage?
- For rental-ready properties – If the property is habitable and can generate rental income immediately.
- For long-term investments – Ideal for investors seeking steady rental returns.
- For lower interest rates – BTL mortgages have significantly lower rates than bridging finance.
What is a Bridging Loan?
A bridging loan is a short-term financing option used to bridge the gap between buying a property and securing long-term finance or selling it for a profit. Bridging loans are ideal for properties that need renovation, conversion, or planning approval before they qualify for a mortgage.
Key Features of a Bridging Loan
✔ Loan Term: 3 to 24 months
✔ Interest Rates: Higher than BTL mortgages (typically 0.5-1.5% per month)
✔ Repayment Type: Interest rolled up (no monthly payments) or serviced
✔ Deposit Requirement: 20%-30% LTV (loan-to-value)
✔ Lender Requirements: Based on exit strategy (sale or refinance)
When to Use a Bridging Loan?
For uninhabitable properties – Ideal for auction purchases that require renovation.
For fast transactions – Securing finance within days rather than weeks.
For development projects – Suitable for conversions, extensions, and HMOs.

Case Study 1: Buying a Property Ready to Rent
Scenario
Sarah, an investor, finds a two-bedroom flat in good condition, currently tenanted. She wants a long-term investment with steady rental income.
Best Option
A Buy-to-Let mortgage is ideal since the property is mortgageable, and she can secure a low interest rate. Use our buy-to-let calculator to estimate potential borrowing based on rental income and property value.
Case Study 2: Buying an Auction Property Needing Renovation
Scenario
James buys a derelict house at auction for £150,000. It lacks a kitchen and bathroom, making it unmortgageable.
Best Option
A bridging loan allows him to complete renovations before refinancing onto a BTL mortgage.
Tips for Investors Choosing Between BTL Mortgages & Bridging Loans
Consider Property Condition: Mortgage lenders require properties to be habitable, while bridging lenders accept refurbishment projects.
Have a Clear Exit Strategy: If using a bridging loan, plan how you will repay or refinance before the loan term ends.
Factor in Costs: Bridging loans have higher interest rates, so they should only be used for short-term funding.
Work with a Specialist Lender: Auction properties and unique investment projects require lenders who understand fast finance.
Final Thoughts
If you’re buying a ready-to-rent property for long-term investment, a Buy-to-Let mortgage is the best option due to lower rates and longer terms.
If you need fast finance for a non-mortgageable property or short-term project, a bridging loan is the right choice.
