Mortgage in Principle and Bad Credit — The Smart Approach
Quick answer — Can I get an agreement in principle (mortgage in principle) with bad credit? Often yes. Most specialist adverse credit lenders will issue a mortgage in principle subject to their full underwriting criteria. Darryl Dhoffer will identify the right specialist lender for your credit profile and arrange the MIP through them avoiding unnecessary credit file searches.

A mortgage in principle also called a decision in principle or agreement in principle is a written indication from a lender that they would be willing to lend you a certain amount based on initial information. Estate agents and sellers often require one before accepting an offer.
With bad credit getting a mortgage in principle requires care. A hard search MIP leaves a footprint on your credit file. Multiple MIPs in a short period can damage your score further. Darryl Dhoffer always conducts a soft search assessment first which does not affect your credit file before recommending which lender to approach for a formal MIP.
Agreement in Principle, Decision in Principle and Mortgage in Principle: Are They the Same?
Yes. "Agreement in principle" (AIP), "decision in principle" (DIP) and "mortgage in principle" (MIP) all describe the same thing: a lender's early indication of how much it might lend you, based on the information you give. It is not a mortgage offer and it does not guarantee approval.
Before You Ask for an Agreement in Principle With Bad Credit
- Find out if the lender uses a soft or a hard search. A hard search leaves a mark on your credit file that other lenders can see. A soft search doesn't.
- Don't apply to several lenders to "see who says yes". Each declined or hard-searched application can make the next one harder.
- Check your credit file first. Look at all three credit reference agencies (Experian, Equifax and TransUnion) so that nothing on your file surprises you.
- Disclose everything. If a CCJ, default, missed payment or IVA is left out, the full application can be declined even when the agreement in principle was approved.
- Have your details to hand: proof of income, ID, the size of your deposit and a list of your regular commitments.
How it fits with a specialist broker. Darryl Dhoffer starts with a free assessment that does not involve a credit search. He then tells you which specialist lender suits your credit profile, so that any formal agreement in principle goes to the right lender first time. Where a hard search would do damage, a broker eligibility letter can sometimes be offered to an estate agent instead.

What an Agreement in Principle Does and Does Not Tell You
- It shows roughly how much a lender might lend, based on the details you gave.
- It is not a mortgage offer, and the full application can still be declined.
- Many lenders run a hard search for it, which can appear on your credit file. Some use a soft search.
- It usually lasts for a limited period, often around 60 to 90 days, depending on the lender.
Why Bad Credit Applicants Are Declined at This Stage
Lenders use automated scoring at agreement in principle stage, so an application can be declined even where a lender's published criteria seem to allow it. Newspage research sponsored by The Mortgage Geezer found the same pattern with CCJs. See CCJ mortgages and what to do if you are declined.
How to Get an Agreement in Principle With Bad Credit: 5 Steps
- Check your credit files first. Look at all three credit reference agencies (Experian, Equifax, TransUnion) so you know what lenders will see.
- Ask whether the search is soft or hard. A soft search does not leave a mark other lenders can see. A hard search does, so several can damage a thin or damaged file.
- Match the lender to your credit profile before applying. Each lender has its own limits on CCJs, defaults, IVAs and missed payments. Applying blind is how people collect avoidable declines.
- Gather your documents. See our list of documents needed for a bad credit mortgage.
- Apply once, to a suitable lender, and treat the result as an indication only. It is not an offer.

Frequently Asked Questions
Is an agreement in principle the same as a mortgage in principle? ›
Yes. Agreement in principle (AIP), decision in principle (DIP) and mortgage in principle (MIP) are different names for the same early indication from a lender. None of them is a mortgage offer or a guarantee of approval.
Should I get an agreement in principle before speaking to a broker if I have bad credit? ›
Usually no. A hard-search application to the wrong lender can leave a mark on your credit file and still end in a decline. It is safer to speak to a specialist broker first, who can point you to the right lender before any formal application.
Can I get an agreement in principle with a CCJ, default or IVA? ›
Often yes, with the right lender. Specialist lenders look at how old the CCJ, default or IVA is, how much it was for and whether it is satisfied. High street lenders are more likely to decline automatically, which is why choosing the lender before applying matters.
Can I get a mortgage in principle with bad credit? ›
Yes. Most specialist adverse credit lenders will issue a mortgage in principle subject to their full underwriting criteria. Darryl Dhoffer will identify the right specialist lender for your credit profile and arrange the MIP through them avoiding unnecessary credit file searches.
Does a mortgage in principle affect my credit score? ›
It depends on whether the lender uses a soft or hard search. Soft searches do not appear on your credit file. Hard searches do and multiple hard searches in a short period can reduce your score. Darryl always recommends a soft search assessment first before any formal MIP application to protect your credit file.
How long does a mortgage in principle last? ›
Most mortgage in principle certificates are valid for 60-90 days. If you have not found a property within that period you typically need to renew it. Darryl will advise on timing your MIP application to align with your property search.
Is a mortgage in principle a guarantee? ›
No. A mortgage in principle is based on initial information only. The full mortgage application involves a detailed assessment of your income credit file and the specific property. It is possible to be declined at full application even with an MIP if the full assessment reveals issues not disclosed at the MIP stage. Darryl ensures full disclosure at MIP stage to avoid this.
Do I need a mortgage in principle to make an offer? ›
Most estate agents request a MIP before taking an offer seriously. Some will accept a letter from a specialist broker confirming your eligibility. Darryl Dhoffer can provide a broker eligibility letter alongside or instead of a formal MIP in situations where a hard search MIP would be damaging.
Can a mortgage be declined after an agreement in principle? ›
Yes. An agreement in principle is not an offer. The lender can still decline at full application after checking your documents, income, affordability and credit file in detail.
Does an agreement in principle affect my credit score? ›
It can. A hard search leaves a record on your file that other lenders can see, while a soft search does not. Check which type the lender uses before applying.
Will an estate agent accept an agreement in principle if I have bad credit? ›
Many will, but some prefer a broker's letter confirming your position, particularly where a hard search could damage your file. A broker can often provide this.
How do I get an agreement in principle with bad credit? ›
Check your credit files, find out whether the lender uses a soft or hard search, choose a lender whose criteria fit your credit profile, and apply once. A specialist broker can match you to a suitable lender first so you avoid unnecessary hard searches. An agreement in principle is an indication, not a mortgage offer.
What do I need for an agreement in principle? ›
Why was my agreement in principle declined? ›
Common reasons are automated credit scoring, recent missed payments, the size or age of a CCJ or default, or income and affordability. A decline at this stage does not always mean every lender will decline you. See
what to do if you are declined.
