Stage 3 of 9

Get your Mortgage Agreement in Principle

An AIP (sometimes called a Decision in Principle) is the letter that says a lender would, in principle, lend you a specific amount. It's not a guarantee, but estate agents won't take you seriously without one.

0 of 0 items ticked

An AIP is a soft check. The lender runs a quick credit search and a basic affordability assessment based on what you tell them about your income and outgoings. They issue a letter saying "based on this, we'd lend up to ยฃX." It's typically valid for 30-90 days.

Two ways to get one: direct from a lender (free, but you're tied to their products), or through a broker (the lender pays the broker, and some brokers also charge a fee, so ask upfront, in return the broker has access to dozens of products to find the best fit). For most people, a broker is the right answer.

What to do at this stage
Decide: broker or direct? (For most people, broker wins)
Have your documents ready, payslips, bank statements, ID
Get the AIP issued (usually within 24-48 hours)
Save the AIP certificate as a PDF, you'll need it for offers
Check the expiry date and diary it
Understand what could change between AIP and full offer
AIP โ‰  Mortgage Offer

An AIP is not a promise. It's a 'based on what you've told us, this looks fine.' The actual mortgage offer comes later, after the lender has verified your documents, valued the property, and run full underwriting. Between AIP and offer, things can change. Don't take on new credit, don't change jobs if you can help it, and don't make big purchases until completion.

When you've worked through everything in this stage, mark it complete to track your overall progress.
