MORTGAGE GUIDANCE

Mortgage in principle explained

Mortgage in principle explained

A mortgage in principle is an indication of how much a lender may be prepared to lend, based on information considered at an early stage. It is also known as an agreement in principle, decision in principle, AIP, DIP or mortgage promise.

It can help you plan a property search, but it is not a mortgage offer or a guarantee that a mortgage will be approved. The lender will carry out further checks before making a formal offer.

Your home may be repossessed if you do not keep up repayments on your mortgage.

THE BASICS

What is a mortgage in principle?

What is a mortgage in principle?

A mortgage in principle is an early indication from a lender of the amount it may be prepared to lend. Different lenders use different names: agreement in principle, decision in principle, AIP, DIP and mortgage promise are commonly used terms for a similar early-stage assessment.

What it can help with

It can give you context for a property search and may help demonstrate to an estate agent or seller that you have considered your mortgage position.

What it does not mean

It is not a mortgage offer, does not guarantee a full mortgage will be approved, and does not confirm that a particular property will meet the lender’s requirements.

A full application involves further checks

Before issuing a formal mortgage offer, the lender will normally assess your full circumstances, supporting documents and the property. The outcome may differ from the earlier indication.

GETTING READY

What information do you need to get one?

What information do you need to get one?

The exact questions and checks vary between lenders. An agreement in principle usually uses the information available at that stage, so it helps to have an accurate picture of your finances and plans.

Your finances

Your income, regular spending, existing borrowing and the amount you plan to contribute as a deposit may all be relevant.

Your deposit

Knowing the size and source of your deposit can help you prepare for the questions a lender may ask later in the application.

Your plans

You may want to think about the property price range, the kind of mortgage you are considering and your wider moving costs.

WHAT TO EXPECT

How does a mortgage in principle work?

How does a mortgage in principle work?

A lender or adviser uses the information you provide to make an initial assessment. Some lenders may carry out a soft credit search, while others may use a hard search, so it is sensible to check what type of search will be used before you proceed.

How long does it take and how long does it last?

Some decisions are available quickly once the required information is supplied. Their validity period can vary by lender, so check the date and any conditions that apply.

How accurate is it?

It reflects information considered at an early stage. The lender may reach a different decision after reviewing evidence, the full application and the property.

Do you need one before viewing or making an offer?

Not always, but an estate agent or seller may ask whether you have considered your mortgage position before progressing an offer.

Can you get more than one agreement in principle?

You may be able to approach more than one lender, but consider the type of credit search each will use and avoid making decisions based on a single early indication.
