Understanding Buy-to-Let Mortgages: A Complete Guide

What is a Buy-to-Let Mortgage?

A Buy-to-Let (BTL) mortgage is a specific type of loan designed for people who want to purchase property as an investment to rent out to tenants. It’s different from a regular residential mortgage because you’re borrowing money to buy a property you won’t live in yourself.

Key Features of Buy-to-Let Mortgages

• Higher Interest Rates: BTL mortgages typically have higher interest rates than residential mortgages
• Larger Deposits: Usually require 25-40% of the property’s value as a deposit
• Different Assessment Criteria: Lenders look at potential rental income rather than just your salary
• Higher Fees: Arrangement fees and other charges are often higher

How Do Buy-to-Let Mortgages Work?

Interest Rate Options

• Fixed Rate: Interest stays the same for a set period
• Variable Rate: Interest can go up or down
• Tracker Rate: Follows another rate (usually ECB base rate) plus a set percentage

Repayment Types

1. Interest-Only: You only pay the interest each month
2. Capital and Interest: You pay both the loan amount and interest
