Income criteria

Interest Cover Ratio (ICR)

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:

ICR
Buy to Let and Let to Buy
HMO and 
Limited Company
HMO
Limited
Company 
Buy to Let
Lower rate tax
Higher rate tax
125%
160%
175%
125%

When calculating the maximum borrowing, this will include any product fees you want to add to the loan. If the product fee is being added to the loan, this can exceed the maximum LTV. But it can't exceed the maximum loan amount.

125% ICR applies to all Limited Company applications (except Houses in Multiple Occupation). And those in personal names where the following criteria is met:

  • Applicants declare themselves to be Lower rate taxpayers and;
  • Declaring their gross annual income is less than £50,271 per applicant, upon completion of the mortgage. This is less than £43,662 gross income in Scotland.
  • Personal applicants can have no more than 3 rental properties (with or without a mortgage). This includes any The Mortgage Works applications in progress.

Of the existing buy to let income input at Decision in principle stage, we'll take into account the following in our assessment of an applicant’s overall income:

  • 75% of all rental income. This includes existing and proposed buy to lets with The Mortgage Works.
  • 100% of all other sources of income.  

Read our 'Understanding affordability' page on how we calculate affordability and how much your client could borrow.

Additional ICR information

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

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 taxpayers and income meets the policy above, we'll require proof of income in the form of the latest SA302. The only acceptable SA302 should cover the years 2023/24. Or tax calculation and the accompanying tax year overview dated within 18 months of the DIP. See table below. 

We'll treat any applicant that has recently left employment, retired or started self-employment as a higher rate taxpayer.

Pay rates

Check our product finder to find out what the pay rate is for your product.

Further advances

We'll continue to stress individual loan elements separately in line with the above. However, the Stress Rate applied to existing lending will be set to a minimum of the Stress Rate applicable to the new borrowing. Please download our further advance calculator for support calculating potential further borrowing.


Minimum income

There is no minimum personal income requirement. Proof of personal income may be requested to support an application. We'll use this with other information relating to the landlord and the property. This is to validate that the loan is going to be used for its intended purpose.

Non-portfolio applications 

We'll carry out further underwriting. We may require additional proofs to support sustainability by requesting one or more of the following evidence: 

  • 3 months' bank statements
  • Personal savings to support 6 months’ rental income
  • Additional household income*
  • Available household funds to act as a sinking fund.*

* We'll only consider household income/sinking fund where the third party is a spouse/ partner of the applicant. They'll need to hold a joint residential mortgage with them.

We may decline the application if we consider the exposure to be too high. For example, where they have a large residential mortgage solely owned. Or a large amount of unsecured debt not consistent with the household income.


Income proofs

We'll require income proofs for landlords using the 125% ICR. We may also request proofs for applications with a 165% ICR or higher. For example if there are high levels of unsecured debt, Nationwide Group BTL exposure over £1million.

Income included in assessment:

  • Gross earned income (employed/ self employed)
  • Pension income
  • Total gross rental income

Acceptable proof of income:

Landlord Type Income type Proof
Experienced Landlord Self employed Tax calculation & Tax Year Overview
Employed/retired
First Time Landlord Self employed
Employed/retired Latest payslip/pension statement
No taxable income 3 months bank statement

Adverse Credit

Where there is adverse credit, we apply a range of factors to determine how we assess applications.

  • In general we won't accept applicants who have had in the last six years: 
    • an Individual Voluntary Arrangement (IVA)
    • a property subject to a previous repossession
    • a County Court Judgement (CCJ) / Court Decree registered against them
    • discharged bankruptcies (we'll consider after 6 years)
  • We also won't consider lending to applicants with:
    • a Bankruptcy Restriction Order or Bankruptcy restriction undertaking in place
    • if applicants are in mortgage arrears. However, we can consider minor historic arrears by exception.
    • current or previous defaults. However, we can consider strong applications by exception.

Top Slicing

We don’t allow surplus earned income to be used to cover any rental shortfall.
