What Is a Mortgage Agreement in Principle and How Do You Get One?
If you have started looking at properties online, chances are you have come across the phrase mortgage agreement in principle at some point. Maybe an estate agent mentioned it. Maybe a friend who recently bought told you to get one sorted. Maybe you saw it on a listing and thought “right, what does that actually mean?”
You are not alone. It is one of those phrases that gets thrown around a lot without anyone really explaining what it involves.
So let us fix that.
What Actually Is a Mortgage Agreement in Principle?
In simple terms, a mortgage agreement in principle is a written statement from a lender saying they would, in principle, be happy to lend you a certain amount of money. It is based on some initial checks rather than a full application, so it is not a guarantee. But it gives you a realistic and honest starting point before you get too deep into your property search.
You might also see it called a decision in principle, a mortgage in principle or an AIP. Different lenders use different names for it but they all mean the same thing.
Think of it as a useful first step that tells you roughly where you stand before you fall in love with a house you cannot actually afford.
Why Does It Matter?
Here is the practical bit.
Having a mortgage agreement in principle does a couple of really useful things. First, it gives you a clear budget. Instead of guessing what you might be able to borrow and browsing properties based on a rough estimate, you actually know. That makes your search a lot more focused and a lot less frustrating.
Second, it shows estate agents and sellers that you mean business. In a competitive market, sellers want to know that a buyer is serious and prepared. Having an agreement in principle ready to go can genuinely put you ahead of someone who does not have one.
Some sellers will not even entertain an offer without one, so it is worth getting sorted sooner rather than later.
What Do Lenders Check at This Stage?
The good news is that it is not as complicated as it might sound.
When you apply for a mortgage agreement in principle, the lender will take a look at a few things to get a sense of your financial situation. That usually includes your income, your existing debts and credit commitments, how much deposit you have and your credit history.
One thing worth knowing is that some lenders carry out what is called a soft credit search at this stage, which does not leave any mark on your credit file. Others do a hard search, which does show up. It is worth checking which type a lender uses before you apply, and this is actually one of the reasons a good mortgage broker is so helpful here. They know which lenders do what, which means they can steer you in the right direction without unnecessary searches building up on your file.
How Long Does It Last?
Most agreements in principle are valid for between 60 and 90 days. If yours runs out before you find somewhere you want to buy, it can usually be renewed without too much hassle.
Just try to keep your financial situation fairly stable during that time. Starting a new job or taking out new credit could affect things when it comes to your full mortgage application later.
Does It Guarantee You Will Get a Mortgage?
Honestly, no, and it is important to be upfront about that.
An agreement in principle is based on the information you provide at that point. When you make a full mortgage application, the lender goes into much more detail. They verify everything, look at bank statements and carry out a full credit check. If everything lines up, great. If something unexpected comes up, it can change things.
This is why being accurate from the start matters, and why having a broker in your corner who can help you prepare properly is genuinely worth it.
How Do You Get One?
You can apply directly with a lender or go through a mortgage broker. Both work, but going through a broker means someone is looking at your full picture first and pointing you towards lenders who are a good fit for your situation rather than just the first name that comes to mind.
At City Mortgage Solutions, helping first-time buyers get their mortgage agreement in principle sorted before they start seriously viewing is something we do every day.
Get in touch with our team and we will walk you through it from the very beginning, no jargon, no pressure.
When Is the Right Time to Get One?
Before you start viewing properties in earnest, ideally.
You do not need to have found a home. You do not need to be ready to make an offer tomorrow. Getting your mortgage agreement in principle in place early just means that when the right property does come along, you are already one step ahead and not scrambling to get things sorted in a rush.
It also helps you avoid one of the most common first-time buyer mistakes we see, which is spending weeks viewing properties without really knowing what you can afford.
One Last Thing
Getting a mortgage agreement in principle does not lock you into anything. You are not committed to that lender. You are not committed to buying. It simply gives you clarity, and a little bit of confidence, as you start your search.
That is never a bad thing.
Frequently Asked Questions
Is a mortgage agreement in principle the same as a mortgage offer?
Not quite. An agreement in principle is an early indication of what a lender might be willing to lend. A mortgage offer is the formal, binding commitment that comes after a full application and property valuation.
Will it affect my credit score?
It depends on whether the lender does a soft or hard credit search. Soft searches do not affect your score at all. Hard searches do leave a footprint, though the impact is usually small and temporary.
How long does it take?
Often the same day, sometimes within a few hours. A broker who knows the market can usually move quickly once they have your information.
Do I need one to view properties?
No, but having one ready makes a real difference when you want to make an offer.
Can I get one if I am self-employed?
Yes, absolutely. It might involve sharing a bit more detail about your income, but it is very much possible. A broker who understands self-employed mortgages can make that process much smoother.
