Why Getting a Mortgage in Principle Makes You a Serious Buyer.

An Agreement in Principle (AIP), sometimes called a Mortgage/Decision/Offer in Principle, is one of the most powerful tools you can have in your home buying journey, especially in today’s fast-moving and competitive market.

Here’s why serious buyers start with having a mortgage in principle.

What is a Mortgage in Principle?

A Mortgage in Principle is a certificate that illustrates how much a mortgage lender is willing to lend you. It is an estimate of how much you can borrow based on a few basic checks, such as income, debt and a soft credit check. It’s not a binding mortgage offer, but it can be a vital first step that proves to sellers and estate agents you’re financially ready to buy.

At The Mortgage Broker, we offer free, no-obligation AIPs that take under 15 minutes. And they won’t affect your credit score.

Why Estate Agents Take You More Seriously with a Mortgage in Principle

Basically, it shows you are offer ready. In a competitive market, hesitation loses houses and Estate Agents will focus on those that are the most serious buyer. An AIP means you can make an offer on the spot if you find the property you want.

You look financially prepared, and Sellers prefer buyers who have already done the groundwork to illustrate they can afford the purchase price.

It speeds everything up and clears the way for the full mortgage application should you want to go to Mortgage Offer.

Is a Mortgage in Principle Essential?
It can be yes. If you are viewing properties that are in high demand or purchasing through a method such as an online auction.

Generally speaking it is better to illustrate proof of affordability, but you do not have to have a mortgage in principle to just see properties. Just imagine it like a car show room. You are affectively walking in with the money in your pocket, and showing them you are a serious customer.
