A Mortgage in Principle, or MIP for short, is also known as an Agreement in Principle, Decision in Principle, Mortgage Agreement in Principle, or a Mortgage Promise. It’s a personalised document confirming an amount of money which a lender believes they would be able to lend you, based on the information you’ve shared in your application.
A Mortgage in Principle is specific to you and, together with your deposit, it can give you an indication of the property price range you can search within. So you can search for your new home with more confidence.
