Income criteria

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.


Stress rates

To reflect the different taxable income levels of landlords, we apply the following stress rates:

Stress rate Product term under 5 years 5 year fixed products 10 year fixed products
65% LTV or below 65.01% LTV to 75% LTV Over 75% LTV 75% LTV or below Over 75% LTV
Remortgage (without capital raising) 4.50% 4.99% 5.50% 4.50% 4.99% 4.00%
All other application types 5.50% 5.99%

Exceptions apply:

  • For 2 year fixed/variable rate products, the higher of stress rate or product pay rate +2% will apply.
  • For 5 year fixed products, the higher of stress rate or product pay rate will apply.
  • For 10 year fixed products, the higher of stress rate or product pay rate +0.75% will apply on all applications.
  • For remortgage applications without capital raising, the higher of stress rate or product pay rate (pay rate +0.50% if variable) will apply for product terms up to and including 5 years. 

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.

For applicants with existing Nationwide Group BTL lending of £1 million or above, an assessment will be made on any existing BTL properties to ensure sustainability (regardless of the number of properties). A stress rate of 5.50% and ICR of 145% will be applied to the client’s existing BTL properties, alongside a maximum aggregate LTV of 65%.

For further advances, individual loan elements will be stressed separately in line with the above.


Interest Cover Ratio (ICR)

In order to ensure the correct ICR is applied to the application, you need to key 100% of all existing BTL income.

To reflect the different taxable income levels of applicants, we have a range of ICRs that are applicable dependant on the customer and/or application. The gross rental income, confirmed by the valuer, must cover the monthly mortgage interest payment by at least:

125% ICR

Applies to Limited Company applications (except HMO) and those in personal names where the following criteria is met:

  • Applicants declare themselves to be Lower rate taxpayers and;
  • Declared annual income is less than £50,000 per applicant, upon completion of the mortgage (less than £43,430 in Scotland).

Of the existing BTL income input at DIP stage, we'll take into account the following in our assessment of an applicant’s overall income:

  • 75% of all rental income (including existing and proposed BTLs with TMW)
  • 100% of all other sources of income.

To qualify for the 125% ICR, applicants can 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 we'll add 75% of the new property’s proposed gross rental income to the applicants’ annual income. For joint applications, we'll add half of the 75% proposed gross rental income to each applicants’ annual income.

In order to validate that all applicants are lower rate tax payers and income meets the policy above, proof of income will be required in the form of a latest SA302 or tax calculation and the accompanying tax year overview (dated within 18 months of the DIP). See table below.


145% ICR

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

170% ICR

  • Applies to all HMO applications, regardless of tax status
