Getting a Decision in Principle (DIP)

A Decision in Principle confirms what we'd be prepared to lend to you. It’s also known as an Agreement in Principle (AIP) or a Lending Certificate.

An estate agent may ask to see your Decision in Principle before they will let you view a property. You’ll be able to download your Decision in Principle certificate from our online application portal.

Stamp duty and your application

The current stamp duty holiday means you won’t pay the tax on a property purchase, up to a certain amount.

Until 30 September 2021, you won’t pay stamp duty on the first £250,000 of a property purchase.

To benefit from the holiday, your mortgage must complete by this date.

If you’re buying in Scotland or Wales, different rules apply.

To find out more, visit the GOV.UK guide to Stamp Duty (opens in a new window).

If you're applying with an LTV between 85.01% and 95%

  • The most we can lend is £500,000.
  • We will only accept applications if you’re buying a house or a bungalow – not for flats, maisonettes, coach house flats or coach houses.
  • We will only accept applications to buy pre-owned properties, not new build homes.

Existing Nationwide mortgage members

  • If you’re applying for a new mortgage, an Early Repayment Charge (ERC) may apply. You’ll find details of any ERC payable on your original mortgage offer.
  • If you want to keep your existing product features, moving your existing deal (porting) to your new home could be right for you.
