What Documents Do I Need For Mortgage Approval?

Applying for a mortgage in Ireland is a big step, and preparation is everything. The more organised you are before you meet with a lender or broker, the smoother the process will be. Having your documents in order not only speeds things up but also shows that you’re financially disciplined, something lenders love to see.

Whether you’re a first-time buyer, self-employed, building your own home or switching lenders, this guide will give you a full picture of the paperwork and information you’ll be asked for.

And if you’ve already had an application refused, don’t worry, you’re not alone. We’ve explained the most common mortgage refusal reasons and what to do next here.

What do I need for a mortgage application?

In most cases, you’ll need the same documents for your application regardless of your financial situation or the details of the property you have in mind. Below, we explain what they are and why you need them – plus some additional documents that specific types of buyers may need.

Your deposit

Under the mortgage lending rules of the Central Bank     , the deposit requirement depends on your situation:

• First-time buyers: 10% of the property value.
• Second-time and subsequent buyers: 10% of the property value.
• Buy-to-let buyers: typically 30%.

For example, if you’re a first-time buyer purchasing a €350,000 home, you’ll need a deposit of €35,000.

It’s important to show where your deposit has come from. Lenders will want to see a track record of savings built up over time, not just a lump sum appearing suddenly. If part of your deposit is a gift (e.g. from parents), you’ll need a signed gift letter stating the funds don’t need to be repaid.

Proof of identification

A valid photo ID is essential. You can use:

• A valid passport, or
• An Irish driver’s licence.

Make sure it’s in date expired documents won’t be accepted.

Proof of your Personal Public Service Number (PPSN)

Lenders are required to collect your PPSN as part of checks with the Central Credit Register (CCR). Your PPSN is typically      found on:

• Your
• A tax assessment from Revenue.
• Correspondence sent from the Department of Social Protection.

Proof of address

To verify your address, you’ll need a recent (within the last three months):

• Utility bill (e.g. electricity, gas, broadband), or
• Bank statement.

Digital statements are usually accepted these days, provided they show your name and address clearly.

Proof of income

This is one of the most important parts of your application. Lenders want reassurance that you can comfortably meet monthly repayments. To prove this, you’ll generally need:

• Employment Detail Summary (from Revenue Online Service). This has replaced the old P60.
• Three months’ worth of recent payslips.
• If your income includes overtime, bonuses, commission or shift allowances, lenders may also request up to three years of Employment Detail Summaries to confirm a track record of variable income.

If you have non-PAYE income (like rental income or freelance work), you’ll need to prove your taxes are fully up to date. This usually means:

• A Revenue statement confirming your taxes are paid, or
• A letter from your accountant confirming the same.

Proof of employment

Your employer will be asked to complete a Salary Certificate. This confirms:

• Your basic annual salary.
• Your employment status (permanent, contract, probation).
• Any regular allowances.

If you’re currently on leave (e.g. maternity leave), your employer will need to provide a letter confirming your return date and that your contract remains unchanged.

Bank statements

Lenders will look at six consecutive months of bank statements for all current and savings accounts. This gives them a snapshot of how you manage your money. They’ll check for:

• Regular savings.
• Rent payments (if applicable).
• Overdraft use.
• Referral fees or unpaid items.
• Gambling transactions.

A few things to keep in mind:

• Make savings and rent payments through your bank account (not cash) so there’s a clear paper trail.
• Set up standing orders with clear labels like “Rent” or “Savings” to make your statements easy to follow.
• Avoid irregular spending and overdraft reliance in the run-up to your application.

Credit card and/or loan statements

Your credit history is checked through the Central Credit Register (CCR). This includes:

• Credit cards.
• Car loans or personal loans.
• Existing mortgages.

If you’ve missed payments or regularly incur late fees, this will count against you. Remember: negative marks stay on your CCR record for up to five years.

To strengthen your case:

• Pay at least the minimum on credit cards every month, ideally clear the balance in full.
• Set up a direct debit for repayments to avoid missing deadlines.
• Reduce outstanding debt before applying.

Additional documents

Depending on your circumstances, lenders may ask for extra paperwork.

If you’re self-employed

The process is more detailed because lenders need to be sure your income is stable. Typically, you’ll be asked for:

• Two to three years of certified accounts, signed off by your accountant.
• Business bank statements (usually sixto twelve months’ worth).
• Revenue Notices of Assessment for the same period.
• A Tax Clearance Certificate.

If you’re building your own home

Self-build mortgages are slightly different. Lenders see them as higher risk due to fluctuating costs and timelines. You’ll need:

• A site map (Property Registration Authority or Ordnance Survey Ireland style).
• Planning permission (with at least 18 months left before expiry).
• Architect or engineer’s report with professional indemnity insurance.
• Project costings and building plans.
• Valuation of the site and build.
• A Certificate of Inspection during the build stages.

Funds are usually released in stages as the build progresses, not as one lump sum.

If you’re switching mortgages

Switching can save thousands over the life of your mortgage, but it still involves a full application process. Lenders will want to see:

• The same core documents listed above (ID, income, bank statements, etc.).
• A redemption statement from your current lender showing your outstanding balance.
• Details of your current mortgage protection policy (you may need to update or replace this when switching).

The new lender will provide a switcher pack, which guides you through the process.

Final thoughts

Mortgage applications can feel paperwork-heavy, but there’s a good reason for it. Lenders want to be sure you’re a safe bet that you can afford repayments, manage your money responsibly      and have the proper documentation to back it up.

The key is preparation. Gather your paperwork early, keep your accounts in good order, and if you’re self-employed or planning a self-build, allow extra time to get everything in place.
