Stress rates and interest cover ratio (ICR)

To reflect the different taxable income levels of landlords, we apply the following Interest Cover Ratios (ICR) and Stress Rates:

Buy to Let and Let to BuyHMO
Tax rate of 20% or lessTax rate of 40% or more
Stress rateProduct term under 5 yearsFixed rates 5 years and over
65% LTV and lower65% LTV to 75% LTVover 75% LTV
Remortgage (without capital raising)4.99%5.50%4.99%
All other application types5.50%5.99%

Exceptions apply:

  • 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 applications, the higher of stress rate or product pay rate + 2% (whichever is higher) 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.

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.

  • 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 in the form of a SA302 or tax calculation see table below

170% ICR

Portfolio landlord affordability assessment

All new TMW mortgage applications are assessed to ensure your client can cover their monthly mortgage interest payment, as per the existing policy.

We’ll also assess their existing portfolio to ensure the overall aggregate LTV and ICR is sustainable. The assessment will be based on the entire portfolio, including the new property and any rental properties without a mortgage.

The following rental calculations and maximum LTVs will apply across your client’s portfolio:

Rental calculation

  • Up to 10 mortgaged BTL properties
  • Nationwide Group BTL Lending up to £1,000,000
  • 11 or more mortgaged BTL properties
  • Nationwide Group BTL Lending over £1,000,000

Maximum LTV

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).

Acceptable income:

  • Gross earned income (excluding bonus, overtime and commission)
  • Pension income
