Congratulations, you’ve received your mortgage in principle! But what happens next? Many buyers aren’t sure what to do after getting an agreement in principle. In this article, we’ll explain the essential actions to take next, from finding a property to securing your mortgage.

What Does Getting Your Mortgage in Principle Mean?

Your mortgage in principle, also called a decision in principle or agreement in principle (AIP), is an indication of how much you can borrow from a mortgage lender. Now that you have a decision in principle certificate, you can start viewing properties with confidence. Your AIP was issued after a soft credit search that didn’t impact your credit score.

What Should You Do Immediately After Getting Your AIP?

Once you get an AIP for the mortgage you want, start viewing properties within your confirmed budget. Your agreement in principle proves you’re a serious buyer to estate agents and sellers. Use a mortgage calculator to understand your monthly repayments at different property prices. Contact estate agents and let them know you have your certificate ready, as this positions you as someone who can move quickly.

How Long Is Your AIP Valid, and Will It Affect Your Credit Score?

Your mortgage in principle typically lasts 60 to 90 days. You should aim to find a property and make an offer before it expires. The soft credit check for your AIP didn’t affect your credit rating. However, you should protect your credit rating now by avoiding new credit applications or large purchases. When you apply for a mortgage later, lenders will run a hard credit check and review your credit history with credit reference agencies.

How Should You Use Your AIP When Making Offers?

When you find a property you love, make an offer and present your mortgage decision in principle to the estate agent. This proves you can afford the mortgage and proceed quickly. In competitive markets, having your certificate ready helps you secure properties faster than buyers who still need to get a decision in principle.

What Documents Should You Gather to Apply for a Mortgage?

While house-hunting, gather the documents for your full mortgage application. These include proof of income, bank statements showing your deposit, proof of identity, and details of outgoings. A mortgage adviser at Eden Hawk can tell you exactly what lenders need, preventing delays.

What Happens When Your Offer Is Accepted?

Once your offer is accepted, contact your lender immediately to progress from agreement in principle to full application. You’ll need to formally apply for a new mortgage with detailed property information.

What Happens During Your Full Mortgage Application?

Your full application involves detailed checks: document verification, affordability assessment to ensure you can afford the mortgage repayment, and property valuation. The lender reviews your financial circumstances thoroughly. This is when you move from “might borrow” to receiving an official mortgage offer. The process takes 2-4 weeks.

Will Your AIP Definitely Lead to an Official Mortgage Offer?

While a mortgage in principle makes it easier to secure lending, it isn’t a guarantee. The lender could decline if your financial circumstances change, the valuation reveals issues, or checks uncover affordability problems. However, if you’ve been honest and nothing has changed since you got your AIP, you should progress smoothly.

Should You Borrow the Maximum Your AIP Shows?

Just because lenders say you can borrow a certain amount doesn’t mean you should. Most lenders offer 4 to 5.5 times your salary. A mortgage calculator can help you choose a mortgage based on your income and consider whether monthly repayments fit comfortably within your budget.

What Should You Avoid After Getting Your Decision in Principle?

Avoid major financial changes: don’t apply for new credit, change jobs, or make large credit purchases that could affect your credit score. These changes impact your full application. Also, don’t delay your property search, since your AIP is valid for a maximum of 90 days.
