A Mortgage In Principle is one of the first (and smartest) steps you can take when starting your journey to buy a home. Also known as an Agreement in Principle (AIP) or Decision in Principle (DIP), it is a statement from a lender saying that, in theory, they’d be willing to lend you a certain amount based on a quick look at your finances.
It’s not a guarantee, but it’s a strong indication of what you can afford – and it shows estate agents and sellers that you’re serious. In fact, many estate agents now ask to see a mortgage in principle before they’ll let you book a viewing. It helps filter out time-wasters and speeds up the buying process.
The good news is that getting one is often fast and free. You’ll usually need to provide some basic details about your income, spending, and credit history, and in return, you’ll get a letter or email confirming how much you might be able to borrow.
At Chatsworth Mortgage Group, we help clients secure their agreement in principle with no stress, no jargon, and plenty of support. It’s a small step that makes a big difference in getting you closer to your new home.
Is A Mortgage In Principle The Same As A Mortgage Offer?
This is a common point of confusion – and one that’s important to clear up. A agreement in principle is not the same as a mortgage offer.
A agreement in principle is a quick snapshot of what a lender might offer you, based on the information you provide. It usually involves a soft credit check and doesn’t require full documentation. Think of it as a helpful estimate.
A mortgage offer, on the other hand, comes later in the process. It’s a formal confirmation that the lender has fully reviewed your finances, credit history, and supporting documents, and they’re ready to lend you the agreed amount – subject to property valuation and legal checks.
So while a mortgage in principle is useful for early-stage planning, it’s not a guarantee. You could still be declined later if your circumstances change, your credit score drops, or issues arise during the full application.
That’s why it helps to work with a team like Chatsworth Mortgage Group. We make sure your agreement in principle is realistic and reliable, and we’re here to guide you all the way through to your final mortgage offer.
What You’ll Need Before You Apply
Before applying for a mortgage in principle, it helps to have a few key bits of information ready. This will make the process quicker and more accurate.
Most lenders or brokers will ask for basic personal and financial details, including:
- Your full name and address history
- Employment details and income (including payslips or self-employment info)
- Monthly outgoings, such as credit card payments or loans
You’ll also need to confirm your identity with photo ID (such as a passport or driving licence) and proof of address. These details help lenders estimate how much you might be able to borrow.
Depending on the provider, they may carry out either a soft or hard credit check. A soft check won’t affect your credit score, while a hard check might leave a mark. It’s worth asking which type they’ll use before applying.
We can help you gather all the right information upfront, so your application runs smoothly and reflects your real situation.
How To Apply For A Mortgage In Principle
Applying for an agreement in principle is often simpler than people expect. You can apply online, through a bank, or with the help of a mortgage broker.
Here’s a step-by-step outline:
- Provide your financial and personal details.
- Agree to a credit check (usually soft at this stage).
- The lender or broker assesses your information.
- You receive a document confirming how much you might be able to borrow.
Some banks issue these instantly online, while others may take a day or two. The document you receive will usually be valid for 60 to 90 days and can be shown to estate agents as proof you’re ready to buy.
With Chatsworth Mortgage Group, we’ll walk you through the whole process, explain every step in plain English, and help you choose the right lender for your needs. It’s quick, stress-free, and fully tailored to you.
How Long Does An Agreement In Principle Last?
A mortgage in principle doesn’t last forever, but it does give you a useful window of time to start your property search. Most are valid for between 60 and 90 days, depending on the lender.
That means you have around two to three months to find a property, make an offer, and progress towards a full mortgage application. If your mortgage in principle expires before you’ve found the right home. Don’t worry, you can usually reapply quite easily, especially if your financial situation hasn’t changed.
Some lenders might ask for updated documents or run another credit check before issuing a new agreement, so it’s a good idea to keep everything on hand just in case.
At Chatsworth Mortgage Group, we keep track of these dates for you. If your mortgage in principle is about to run out, we’ll remind you and help you renew it with minimal fuss, so you can stay focused on house hunting.
Will It Affect My Credit Score?
One of the biggest concerns people have is whether applying for an agreement in principle will damage their credit score. The good news is that most lenders only carry out a soft credit check at this stage.
A soft check allows the lender to see your credit history without leaving a mark on your report. It won’t impact your score and won’t be visible to other lenders. This means you can apply for a mortgage in principle without worrying about affecting your chances of getting credit elsewhere.
Some lenders do use hard credit checks, which do appear on your report and may impact your score slightly, especially if multiple checks are done in a short period. Always ask which type of check will be used before you apply.
We only work with lenders that explain this upfront. We’ll help you make informed decisions and protect your credit profile while getting you ready for the next step.
Common Questions First-Time Buyers Ask
Can I make an offer with just an agreement in principle?
Yes, most estate agents and sellers are happy to accept offers from buyers who have a mortgage in principle. It shows you’re serious and gives confidence that your finances are in order.
Can I be declined for a mortgage later, even with a mortgage agreement in principle?
Unfortunately, yes. An agreement in principle is based on the initial information you provide. If anything changes, or if issues come up during your full application – such as a lower credit score or problems with the property you may still be turned down.
What happens after I get a mortgage in principle?
You can start viewing properties and making offers. If your offer is accepted, the next step is to submit a full mortgage application, which involves a detailed review and a property valuation.
Do I need an agreement in principle to view properties?
Not always, but many estate agents prefer it. It helps filter serious buyers from those just browsing. Some sellers may even prioritise buyers who already have one in place, especially in a competitive market.
Will having a mortgage agreement in principle speed up the process?
Yes. It means you’ve already done the groundwork, so when you find the right property, you can move quicker. It also helps avoid delays when dealing with brokers, solicitors, and lenders later on.
Can I apply for more than one mortgage in principle?
You can, but be cautious. Too many hard credit checks in a short time may affect your score. Always check whether a lender uses a soft or hard search first.
