What is a Mortgage in Principle (AIP or DIP)?
A Mortgage in Principle (sometimes called Agreement in Principle or Decision in Principle) is a quick mortgage lender estimate of how much you may be able to borrow based on your basic information such as your income. No formal documentation is required and it is not a binding mortgage offer, but it does provide instant clarity and demonstrates affordability to estate agents and sellers. It usually takes under 15 minutes to complete and you will get a downloadable mortgage in principle certificate.
How long does a Mortgage in Principle last?
Most AIPs are valid between 30 and 90 days. You’ll receive a digital certificate which specifies the exact duration as they can differ from lender to lender. If you don’t go through with a mortgage in the time frame and it expires, it is easy to get another one reissued during your property search.
Will a Mortgage in Principle affect my credit score?
No. We use soft credit checks only, which do not appear on your credit file or affect your credit score. You can reapply if your AIP expires or whilst you are making offers.
Does an AIP guarantee I’ll get a mortgage?
Not always, but it is a very good indication. A Mortgage in Principle is an estimate and is not guaranteed as final approval will always depend on full affordability checks, once you provide documentation and the property valuation is confirmed. We help guide you to strengthen your case throughout.
What documents do I need to get a Mortgage in Principle?
Officially speaking, it is possible to run a mortgage in principle soft credit check with just your income information. Of course, the more information available, the more chance that the mortgage in principle will accurately reflect what you can afford to borrow. If you chose to proceed with a mortgage application after your mortgage in principle certificate, then there are further checks to ensure the income information is accurate, and hard checks on your credit file to ensure there is nothing we weren’t aware of.
How fast can I get an AIP from The Mortgage Broker?
If you qualify, we can generate your AIP in under 15 minutes using our integrated technology and mortgage lender access. If you have found a property, we can get you offer ready quickly, or whilst house hunting, it is designed to provide immediate clarity and confidence whilst you are searching. Ultimately, it is better not to rush it as we want to ensure we search the 25,000+ products available.
Do you offer Mortgage in Principles for Buy to Let?
Yes and often Buy to Let applications require a mortgage in principle before making offers. The process is a bit different as lenders focus on the bigger picture, which includes your rental income and your property portfolio, rather than just your personal income. We’ll guide you through what’s needed, including stress tests and deposit amounts.
Can I get more than one Mortgage in Principle?
Yes you can get more than one mortgage in principle, and if you already have one, The Mortgage Broker can run a comparison and check it is the right one. In some cases, it can actually help to have more than one. If you’re comparing options or need an updated AIP with a new lender, we’ll help you get what you need. We make sure it doesn’t affect your credit and give you clean advice to move forward.

Frequently Asked Questions – Mortgage in Principle for your circumstances
Can I still get a Mortgage in Principle if I’ve got bad credit?
Yes, even with missed payments, defaults or CCJs, it is still possible to get a mortgage in principle. It is very normal to have such things on your credit file and it just means we may need to look at more specialist lenders who understand your situation. We work with over 130 lenders, including those who support clients with adverse credit. It is much better to be open as we have seen it all, and if you’ve got intent and honesty, we’ll do everything we can to help. Don’t worry, we have seen thousands of bespoke and complex scenarios which have resulted in a bad credit mortgage in principle being approved.
Read more about bad credit mortgages.
What deposit do I need with bad credit?
Usually 15% or more. If your credit issues are minor and you’ve got strong income, it could be lower, but generally speaking, the worse the credit, the higher the deposit needed. The good news is we’ll give you a clear picture up front and quickly, so that we can help you build a path to get there.
Can I get a Mortgage in Principle if I’m self-employed or a contractor?
You certainly can get a mortgage in principle being self employed, or a contractor. It’s one of the greatest myths in mortgages that being self employed means you can’t. It is however, very important to package applications correctly. We do have Lenders who accept less, but the standard is that mortgage lenders will want 2 years of accounts or SA302s, or may review your current contracts if you’re a contractor. We have specialists in this field and will make sure your income is properly presented and your affordability makes sense to lenders.
How much can I borrow if I’m self-employed?
Borrowing calculations for self employed depend on your income and how it’s presented but we will aim to get you 5.5x your income. Some mortgage lenders will use your average over two years, others might just take your most recent year. Contractors can sometimes borrow more using their day rate. It is key to get advice here, as we can establish your needs and select the right criteria to go for as we know how each lender calculates things. We will find you one that works best for your circumstances.
I’ve just gone self-employed – can I still get a Mortgage in Principle?
Yes, but it’s a little more complex if you are newly self employed. Most lenders want at least one year of trading history, sometimes two. If you’ve recently transitioned from a PAYE role in the same industry, or have a strong contract in place, we may still have options. We’ll review it all and give you a real answer once we know the exact position and assess the most appropriate mortgage lender for you.

Can I get a Mortgage in Principle on a weekend or out of hours?
We can gather all the information 24/7 that we require to run you a mortgage in principle. At The Mortgage Broker, we are all about speed and delivery, and we have all the digital tools and A.I. in place to do things online. However, we always chose to only gather information out of hours, and run this quickly with a specialist adviser when we are back in office hours. That way we can be sure it is the right mortgage in principle certificate for your circumstances.
We are open 6 days a week, but have 24/7 live chat if you submit an enquiry.
Can I get more than one Mortgage in Principle?
You can – and in some cases, it helps. If you’re comparing options or need an updated AIP with a new lender, we’ll help you get what you need. We make sure it doesn’t affect your credit and give you clean advice to move forward.
The mortgage deal The Mortgage Broker found us came to £300 less per month, than our original AIP told us from a different broker, and we had our mortgage offer within a week of applying.

Getting a Mortgage in Principle
Get StartedA mortgage in principle, means that the lender has indicated their willingness to loan a certain amount of money based on the initial facts they have received. This is a principle agreement, which illustrates they are happy with the initial circumstance of the borrower and the amount required on the mortgage. However, it is not a financial commitment and always depends on a full assessment of the borrower’s as well as on the property being purchased.
The most common term for a lender giving an acceptance on the initial facts is a decision in principle. However, this is also known as a mortgage in principle, an agreement in principle or an offer in principle. Fundamentally, they are all just different ways of saying the same thing. The important fact is, the lender has accepted the initial affordability and circumstances of the borrowers financial position.
No. However, this does illustrate that you are mortgage ready having satisfied initial checks and this does carry a lot of weight when making an offer on a property. This is sometimes a requirement and puts you in a much better position than others with estate agents, or other means such as auction. However, a decision in principle is not a financial commitment from the lender.
Can I get an mortgage in principle with The Mortgage Broker?
Yes.
Buying a property is stressful enough, worrying about the mortgage is something you simply don’t need to have on your plate. Whether a first time buyer, an experienced property landlord or are looking to move home, our team at The Mortgage Broker are focused on getting you mortgage ready in the fastest and simplest way possible.
Our goal is to ensure you understand your financial position clearly, with transparent advice and thorough searches of the mortgage market options available, so that we can get you that offer in principle and put you in a strong position for your property purchase.
With some simple information, we can access lenders, and understand if they are willing to provide an offer in principle to you, based on your financial position.
Therefore, to answer the question, can you get an mortgage in principle? You simple speak with our expert mortgage advisers so we can understand the income of all the applicants (if there is more than just you buying), how much deposit you have and how much you are looking to borrow. With this we can assess your affordability and eligibility against different lenders criteria and then assess whether you can get an offer in principle. This can be done with out the need for looking at your credit file, and all documentation if we are confident you have provided the information. However, this will all be required for a full mortgage application.
You don’t necessarily need to know how much you want to borrow if you haven’t yet found a property. We can advise you how much you may be able to get via a mortgage and the costs associated with this, with all other costs such as stamp duty considered in our affordability checks. We can then get an offer in principle for you, so you are mortgage ready.
The Mortgage Broker have over 12,000 mortgage products available to us across our panel of 96+ Lenders, and we understand which Lenders criteria may suit your circumstances best. If we can get your information up front as efficiently as possible, then we can quickly determine the right lender that fits your needs and apply for an offer in principle within a very short time frame.
There are two different types of searches that lenders will do to assess whether you are eligible for an offer in principle or not. In order to get an offer in principle, some lenders only require a “soft footprint search” or “soft credit check”. This enables pre-approval, and checks your credit report for informational purposes only. These background checks do not affect your credit score and are not visible to other lenders. The reason for a soft search, is that it enables high level background checks identity verification and a credit search as mentioned, in order to satisify the pre-approval process of an offer in principle. This will include searches for things such as credit card debts and loans. A full search however, also commonly known as a “hard search” or “hard credit check”, is more visible as it indicates that you are actively seeking credit by way of a mortgage. If you want to get a decision in principle from a lender and this includes a more formal credit report and background check, our team of mortgage advisers will be sure to talk you through this as it is important to know the impact of these. The reason for this is because it can have a negative impact on your credit file if you are refused a decision in principle which other lenders can then subsequently see. To ensure you are not affecting your credit score negatively, it is important to get an offer in principle through a mortgage broker, as their experience and knowledge of lending criteria, will ensure you go the right lender for your circumstances.Will you search my credit file to get an offer in principle?
What steps does a mortgage broker do to get an offer in principle?
Once our mortgage advisers gets the basic information from you, such as income, employment status, deposit, goals etc, the steps taken to get an offer in principle are typically as follows:
- Research Lenders
Searching the market for the best rate, and most suitable mortgage for your situation is key to a successful mortgage in principle. This will ensure that only the lenders that will support your product needs are considered.
- Application
The Mortgage Broker are integrated with Halifax and can get you an offer in principle within 15 minutes. We have over 12,000 other products that we can quickly search, and we can complete an application for you via our service and platforms. Of course, we also have years of relationship building and creditability behind us, so we do it online, but also speak over the phone directly if required.
- Credit Check
The lender will always perform a credit check when assessing the viability of your mortgage application. For an offer in principle, this is often just a soft check, but our team of advisers all know exactly which lenders do what and will advise you on this. The credit check is an important part of the process to establish creditworthiness and helps the lender to determine how much they are willing to lend you.
- Assessment
The lender will assess all the information that we provide them. This process is becoming increasingly digital and it is imperative that the information is presented correctly to ensure the best chance of finding the most cost-effective mortgage offer in principle.
- Decision
If all is successful with the information and application, then the lender will provide you with an offer in principle. This essentially outlines an initial acceptance based on the facts and illustrates how much the lender is willing to lend you.
The decision in principle is not a guaranteed offer of a mortgage. It is an indication of how much the lender is willing to lend you, but this is always subject to further checks and assessments by way of an income and expenditure budget review. This is why is is so important to use a mortgage broker when applying for a decision in principle, to ensure that you are presented correctly, and are applying to lenders that we know will follow through with their initial decision based on the criteria they have and your financial circumstances.
Do I have to get a decision in principle to make an offer on a property?
This depends on the method of your property purchase. It is becoming more and more common, that properties are being bought and sold via online auction. If you are purchasing through an online auction, more recently known as the Modern Method of Auction, then you are required to have a decision in principle before making an official bid. This is because you are expected to complete within 56 days and you must be mortgage ready to make this commitment.
Generally speaking though, it is not a requirement to have a mortgage offered in principle in order to make an offer on a house. Estate agents and sellers will take you more seriously as a buyer, but it is not normally a requirement. Sellers can stipulate that they require you to prove you have a decision in principle before considering your offer.
