The application

Buy-to-let definitions

We do not lend on MCOB regulated buy-to-lets i.e. Where the property is being let to a family member. Consumer buy-to-let (CBTL) rules will apply to remortgage applicants who don’t own any other let properties and either:

  • Wish to let their current residence whilst purchasing a new residential property (known as a let to buy)
  • Have inherited the property and wish to let it 
  • Have themselves or a close relative, previously resided in the property, and now wish to let it. 
Investment Property Loans (IPL) will apply to anyone either:
  • Purchasing a property specifically to let
  • Remortgaging an existing rental property
All advisers submitting a CBTL application will need to hold the relevant CBTL FCA permissions in addition to their normal mortgage permissions.

The way we assess buy-to-let applications and the choice of products on offer will be the same for both CBTL and IPL.

Rental income

The rental income must cover at least 160% of the monthly interest part of your mortgage payment, which is currently calculated at 4.25% on an interest only basis.

  • The rental income is based on your estimate, subject to confirmation from the valuer. The valuer will assess the rental income based on a family dwelling for an unfurnished property.
