Buy to Let Mortgage Calculator

Our buy to let calculator assesses a landlord’s affordability for a mortgage based on the likely or actual rental income that the property is able to achieve. The calculator is able to accommodate a range of buy to let sectors, including standard, limited company, Consumer Buy to Let and regulated ‘family’ buy to let.

You will need to enter your loan type, whether you’re a higher rate tax payer, the loan amount and rental income together with the rate of your intended product. You can find our current range of buy to let mortgages on our website.

Our buy to let mortgage calculator will then give a simple pass or fail result, or ask you to refer to one of our Mortgage Advisers or our Intermediary Sales Support team, where they can find out more about your circumstances and assess your affordability more closely.

Holiday Let mortgages and the use of background or earned income (Top Slicing) are assessed differently. If you would like us to consider either of these options in an affordability assessment, please contact us to find out more.

The calculator results are for illustrative purposes only and the result is not a mortgage offer or a decision in principle. All mortgage applications are still subject to full underwriting checks.

To discuss an application in more detail, our mortgage advisers are available on 01623 676345, mortgage intermediaries should call 01623 676360 or you can enquire online.
