How Much Can I Borrow with a Buy to Let Mortgage?
- The amount you can borrow depends on the rental income you expect to earn from the property.
- Typically, you’ll need a higher deposit amount for a Buy to Let mortgage, usually 25% of the property value.

Mortgage Interest Rates and Fees

Applying for a Buy to Let Mortgage
Agreement in Principle

- You may need to provide additional documentation, such as proof of rental income or property valuations.

Remortgaging and Changing Mortgage Terms
Remortgaging Options
- You can remortgage your existing Buy to Let property to take advantage of better interest rates or to release equity.

- You can remortgage with the same lender or switch to a different lender.
Additional Considerations
Buy to Let Mortgage Types

Small Portfolio Landlords
