What is a Buy-to-Let Mortgage?
A buy-to-let (BTL) mortgage is designed specifically for individuals who want to purchase property to rent it out rather than live in it. These mortgages have different eligibility criteria and are assessed largely on expected rental income, not just your personal salary.
We’ll help you understand the rules, costs, and tax considerations—ensuring you make the most informed decision for your investment.

- Rental income must meet minimum coverage (usually 125–145% of mortgage payments)
- Landlord insurance may be required
