Stress rates and interest cover ratio (ICR)

To reflect the different taxable income levels of landlords, we apply the following rental checks to ensure your client can cover their monthly mortgage interest payment:

Tax rate
Stress rate
20% or less
40% or more

Exceptions apply:

4.99% stress rate
• A fixed rate product that has a term of 5 or more years
• A remortgage up to and including 65% LTV without capital raising
5.99% stress rate
• Overall Buy to Let lending with the Nationwide Group is over £1m (before or after the new loan)
170% ICR
• Applications for Houses in Multiple Occupation (HMO) regardless of tax status

  • For remortgage applications without capital raising and fixed rate product terms of 5 or more years, the higher of stress rate or product pay rate (product pay rate + 0.50% for variable products) will apply.
  • For all other applications, the higher of stress rate or product pay rate + 2% will apply.
  • For Further Advance applications where the existing product is ending within 3 months, the higher of follow on rate + 2% or 5.50% will be used to stress the existing loan.
  • For existing customers switching products, no rental assessment will apply.

5.50% stress rate applies for all other applications.

For remortgages, we'll apply the lower of the current rent or estimated rental value as given by the valuer. Rental income denominated in a currency other than pounds sterling (GBP) isn't accepted.

Interest Cover Ratio

125% ICR

  • Landlords must be lower rate tax payers (gross income of £45k or less in England/Wales or £43k or less in Scotland) upon completion of the mortgage.
  • Landlords must have no more than 3 rental properties (with or without a mortgage), including any TMW applications in progress.
  • For purchase and Let to Buy applications, 75% of the proposed gross rental income will be added to current gross income to account for the increase in taxable income.
  • Proof of income will be required see table below

145% ICR

  • Applies to landlords who don't meet the criteria above

170% ICR

  • Applies to HMO applications, regardless of tax status

Minimum income

There is no minimum personal income requirement, however, proof of personal income may be requested to support an application. This will be used with other information relating to the landlord and property, to validate that the loan will be used for its intended purpose.

Income proofs

Income proofs will be required for landlords using the 125% ICR and may be requested for applications with a 145% ICR or higher (e.g. if there's high levels of unsecured debt, Nationwide Group BTL exposure over £1m).
