How does this buy-to-let calculator work?

This calculator assumes that:

  • You have £25,000+ income a year
  • You're not a first time buyer
  • You have a deposit of at least 20%

Increase your property value. Because almost all buy-to-let lenders need a deposit of 20% from you, this calculator caps the amount you can borrow at 80% of the property value. You might be able to borrow more than it shows you: create an account and we'll find out for you.

Increase the monthly rent. Lenders usually want your monthly rent to be 25% higher than a high 'stress test' interest rate they set to test your application. If you're able to charge tenants a higher rent, that usually means you can borrow more.

Lenders usually want a minimum 20% deposit for buy-to-let properties. Your deposit doesn't affect how much you can borrow, but it does open up cheaper interest rates for you.
