Buy to Let
mortgage calculator

Mortgage calculators

Buy to Let mortgages have different eligibility and affordability requirements to standard mortgages. In addition to general affordability stress testing, lenders also stress test Buy to Let mortgages based on the expected rent.

Use this Buy to Let mortgage calculator to work out

  • How much you could potentially borrow based on the expected monthly rent paid by the tenant.
  • The minimum monthly rent you need to potentially secure a Buy to Let mortgage amount.

How much can I borrow?

Mortgage calculator
Lenders normally only lend up to 75% of the property value, may apply a different rental stress test calculation based on your income level and other criteria. With this in mind, you will benefit greatly from talking to one of our expert mortgage advisors about your Buy to Let plans.

How much rent do I need?

Mortgage calculator
This Buy To Let mortgage calculator is aimed at giving you an idea of how much rental income would be required to borrow a certain Buy to Let mortgage amount. However, as lenders use different mortgage stress testing figures for calculation purposes, the actual required rent amount will likely fall between the figures displayed.
