Portfolio landlord criteria

The Mortgage Works portfolio landlord definition

A portfolio landlord is a borrower with four or more distinct mortgaged Buy to Let UK rental properties (or seven or more for remortgage applications without capital raising).

Additional information

This includes properties owned through a limited company, 'consent to let' properties and all BTL mortgages owned solely or jointly by the applicant(s).

We'll only accept applications from portfolio landlords that have at least two years' letting experience (at least one applicant must meet this requirement on joint applications). We won't consider foreign properties when assessing portfolio landlords.

If there are two applicants, we’ll use the combined number of rental properties for both. For example, if the first applicant solely owns three mortgaged properties and the second applicant solely owns five properties, they would collectively own eight properties in the portfolio.

Affordability assessment

All new mortgage applications with The Mortgage Works are assessed to ensure your client can cover their monthly mortgage interest payment.

We'll also assess the 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.

We have different products depending on the size of your client's portfolio, so please make sure to check our latest product guide prior to application. 

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

Existing portfolio rental calculation

Maximum LTV
Stress Rate
Interest Cover Ratio (ICR)
Up to 10 mortgaged BTL properties at completion
75% 4.50%

11 or more mortgaged BTL properties at completion
65% 5.50%

For applicants whose total BTL lending with the Nationwide Group BTL exceeds £1 million on completion, a stress rate of 5.50% will be used to assess the client’s existing and proposed BTL properties, alongside a maximum aggregate LTV of 65% (regardless of the number of properties).

Keying applications in TMW Online

  • We ask for your client's personal income on all cases.
  • At DIP stage, we look at gross annual buy to let income as well as the total number of properties, to identify if your client is/will be a portfolio landlord on completion of the application.
  • If your client has 4 or more mortgaged properties, we'll ask for details of the total value and outstanding mortgage balances secured against the portfolio.

Please note:

  • If a BTL property is jointly owned between your clients, you only need to enter them under one applicant, not both.
  • If you're creating multiple applications for the same applicant(s), please try to submit them at the same time.

Packaging applications (including Portfolio Portal)

Portfolio landlords with 11 or more mortgaged BTL properties need to provide three months' current account statements showing rental payments for their portfolio

All portfolio landlords will need to provide a property schedule, either by:

*When uploading the TMW property schedule form directly into the portal, please don't insert new columns into this spreadsheet, copy and paste over the cells or provide any additional information we haven't requested, as this will cause upload errors.

Once submitted, the details will be automatically validated and the results will be sent to our dedicated team of underwriters for assessment. We'll be able to assess the case more quickly if you're able to complete this as soon as you've completed the application.

See our Portfolio Portal guidance notes for more information.

Depending on case complexity and portfolio size, we may request further supporting information such as a business plan.

So your case can be processed efficiently, please submit all requested proofs and additional supporting information, but only when this is asked for.
