Demystifying Mortgage Terminology
When entering the property market, buyers encounter a confusing array of acronyms and terms. Two of the most commonly used, and often misunderstood, are AIP and MIP. As multiple mortgage lenders and financial advisors confirm, these are not distinct products but rather different names for the exact same thing: a preliminary, non-binding assessment of your borrowing potential. The core function of this document is to give you a clear, early indication of your budget, making you a more attractive prospect to estate agents and sellers.
What is an AIP (Agreement in Principle)?
An Agreement in Principle, or AIP, is a written or digital document from a mortgage lender outlining the amount they are provisionally prepared to lend you. This estimate is based on the information you provide about your income, existing debts, and credit history during an initial check. It is important to note that an AIP is not a formal mortgage offer and is subject to further checks and the lender's final valuation of the property you intend to buy.
- How to get one: You can obtain an AIP directly from a lender online, over the phone, or with the help of a mortgage broker. The process is typically quick and often involves only a 'soft' credit check, which doesn't affect your credit score.
- What it contains: The document usually specifies the maximum amount you can borrow, subject to verification of your income and financial details in a full application. It may also list the type of mortgage product, though this is provisional.
- Purpose: An AIP serves as proof to sellers and estate agents that you are a serious buyer who is financially capable of making an offer on a property within a specific price range.
What is an MIP (Mortgage in Principle)?
Similarly, a Mortgage in Principle (MIP) is a statement from a lender that essentially serves the exact same function as an AIP. The difference lies purely in the terminology used by various financial institutions, with some favoring MIP and others using AIP. Like an AIP, it is a non-binding estimate of a potential loan amount and does not guarantee that a formal mortgage will be granted later.
- Process: The application process for an MIP is identical to an AIP, involving an initial financial review that provides a preliminary borrowing figure.
- Value in the market: Presenting an MIP to an estate agent during the property search can give you a significant edge over other buyers who have not yet secured pre-approval.
- Not a promise: It is a common misconception that an MIP is a formal loan offer. It is merely an indication of what a lender might be willing to lend you, assuming all the details you provided are accurate and the property valuation meets their criteria.

Why the Different Terms Exist
The interchangeable use of AIP, MIP, and sometimes DIP (Decision in Principle) can be attributed to the lack of standardized terminology across the mortgage industry. Different lenders and brokers have adopted their own preferred term to describe this initial stage of assessment. For the homebuyer, understanding that these terms refer to the same process is the most crucial takeaway. The specific name on the document is far less important than what it represents: a crucial step in preparing to buy a home.
Ultimately, whether your lender provides an AIP or an MIP, the objective is the same: to give you a strong starting point for your property search. It allows you to focus your efforts on homes within your budget and provides a level of reassurance to sellers and agents that you are a qualified and serious buyer.

Conclusion
In summary, the distinction between an AIP and an MIP is purely semantic. Both terms describe the initial, non-binding agreement from a lender that estimates your borrowing potential based on your financial details. For prospective homebuyers, the focus should not be on the name of the document, but on leveraging this preliminary approval to navigate the competitive housing market with confidence. By obtaining either an AIP or an MIP, you establish a clear budget and demonstrate your readiness to proceed with a purchase, streamlining your home-buying journey.
