Approval in Principle Ireland: What It Is, How Long It Takes, and What Comes Next

You can't put in a serious bid on a house in Ireland without an Approval in Principle. Estate agents won't take you seriously, and sellers won't engage. But many buyers don't fully understand what AIP actually confirms, how long it takes to get, and — critically — what it doesn't guarantee.

Here's everything you need to know before you approach a lender.

What Approval in Principle Actually Means

Approval in Principle (AIP) is a conditional commitment from a lender that, based on the information and documentation you've provided, they are prepared in principle to offer you a mortgage up to a specified amount.

The key word is "conditional." AIP is not a binding mortgage offer. It does not commit the bank to lending you that amount. It confirms that you've passed the lender's initial eligibility assessment, income verification, and financial history review. Full mortgage approval — the actual loan offer — comes later, after a specific property has been valued by the bank's approved valuer and the bank's legal team has reviewed the property title.

AIP is what allows you to bid competitively. Without it, you're effectively asking a seller to wait while you work out whether you can afford to buy.

Documents Required for an AIP Application

Getting your documentation together before you approach a lender will determine how quickly the process moves. Irish lenders typically require:

Identity and residency: Passport or national ID, plus proof of current address (utility bill or bank statement less than three months old).

Income documentation: Three months of recent payslips and a letter from your employer confirming your permanent employment status, current salary, and contract type. If you've recently started a new job or are in a probationary period, many lenders will require you to wait until probation is complete.

Self-employed applicants: Two years of audited accounts signed by your accountant, and two years of Revenue notices of assessment (the official tax confirmation from Revenue that shows your assessed income).

Bank statements: Six months of statements from all bank accounts — current accounts, savings accounts, and any loan accounts. This is where lenders scrutinize your financial behaviour. Consistent savings growth, regular rent payments, and clean account management matter significantly.

Evidence of deposit: Bank statements showing your deposit savings history. If any of your deposit is coming from a parental gift, the giftor typically needs to sign a letter confirming the gift is non-repayable.

Existing commitments: Details of any existing loans, credit card balances, or Buy Now Pay Later agreements.

How Long Does an AIP Take in Ireland?

Processing times vary by lender and time of year, but as a working estimate:

• Online-first lenders and credit unions: 5 to 10 business days for a straightforward application with complete documentation
• Bank branch applications: 2 to 4 weeks depending on the lender and underwriter queue
• Broker-assisted applications: Typically faster, as brokers know which lenders are moving quickly at any given time

The biggest delays come from incomplete applications. If a document is missing or unclear, the underwriter will request it and your application goes to the back of the queue. Get everything together before you submit, not after.

How Long Does AIP Last?

Most lenders issue AIP letters valid for six months. You can typically extend an AIP for a further six months by submitting updated payslips and bank statements. If your financial circumstances haven't changed, renewal is usually straightforward.

If your AIP expires before you go sale agreed, you'll need to reapply — which resets the process and requires fresh documentation.

AIP and LTI Exceptions: A Critical Distinction

Most AIP letters are issued at the standard Central Bank limits — four times your gross income, 90% LTV. If you're hoping to secure an LTI exception (borrowing up to 4.75 times your income), many lenders will not commit to the exception at AIP stage.

Instead, they issue AIP at the standard rate, with a note that you may be considered for an exception once you're sale agreed on a specific property. This creates a frustrating situation: you may be bidding on homes you couldn't technically afford under your AIP limit, trusting that the exception will be approved once you go sale agreed.

The way to manage this risk is to be very clear with your mortgage broker or lender about whether the exception is integral to your purchase plan. Some lenders are more willing to pre-approve exceptions than others. A broker who works across multiple lenders can identify which institutions are currently more flexible on this front.

What Happens Between AIP and Full Mortgage Approval

Once you're sale agreed on a property:

1. Bank valuation: The lender appoints their own approved valuer to assess the property. You pay a fee (typically €150 to €300) for this valuation. If the bank's valuation comes in below the sale agreed price, the bank will only lend against the valuation figure — not the purchase price. You'd need to fund the gap yourself or renegotiate with the seller.

2. Loan offer: Once the valuation is satisfactory, the bank issues a formal loan offer (also called a letter of sanction). This is the binding mortgage commitment.

3. Mandatory insurance: Before the bank releases funds, you must have mortgage protection insurance and buildings insurance in place. Both must be submitted to the lender.

4. Drawdown: Your solicitor arranges the transfer of funds on closing day. The mortgage is drawn down at this point.

Should You Use a Mortgage Broker?

Mortgage brokers in Ireland work across multiple lenders, which gives them insight into who is moving fast, who is likely to approve exceptions, and which lenders are best placed for your income profile. Given that broker fees are typically paid by the lender rather than you, there's a reasonable case for using one — particularly if your application is anything other than straightforward (self-employed, recently changed jobs, higher LTI request).

Brokers can also help you present your application in the strongest possible way, identify the right lender first rather than making multiple applications, and manage the documentation process.
