Buying a home in Ireland is not just about finding the right property. One of the biggest questions buyers ask is simple: how much deposit do I actually need?
The short answer is that it depends on whether you are a first-time buyer, a second or subsequent buyer, or buying an investment property. Your lender also has to follow the Central Bank’s mortgage measures, although there are limited exceptions.
Here is a practical guide to what buyers in Ireland need to know in 2026.
The basic deposit rules in Ireland
In Ireland, mortgage lenders are generally bound by loan-to-value (LTV) limits set under the Central Bank’s mortgage measures. LTV is the percentage of the property price you borrow compared with the property value.
Your deposit is the part you pay from your own funds.
First-time buyers
If you are a first-time buyer purchasing a home to live in, you can typically borrow up to 90% of the property value. That means you usually need a 10% deposit.
Example:
- Home price: €350,000
- Maximum mortgage at 90%: about €315,000
- Minimum deposit: about €35,000
Second and subsequent buyers
If you have bought a home before and you are buying another principal residence, you can typically borrow up to 80% of the property value. That means you usually need a 20% deposit.
Example:
- Home price: €350,000
- Maximum mortgage at 80%: about €280,000
- Minimum deposit: about €70,000
Buy-to-let buyers
For buy-to-let properties, the general maximum is lower again. A lender will usually lend up to 70% of the property value, so buyers generally need a 30% deposit.
Because this article is aimed at home buyers, the rest of this guide focuses mainly on owner-occupier purchases.
Deposit is only one part of affordability
A common mistake is thinking that if you have the deposit, you are ready to buy. In reality, Irish lenders also apply loan-to-income (LTI) limits.
For many borrowers, the standard limit is based on a multiple of your gross income. This means your deposit might be enough, but your income may still cap how much you can borrow.
So in practice, the amount of house you can buy is usually limited by whichever is lower:
- the LTV rule based on your deposit, or
- the LTI rule based on your income
That is why two buyers with the same savings can end up with very different budgets.
Can a bank lend more than the standard deposit rules allow?
Sometimes, yes.
The Central Bank allows lenders to make a limited number of loans outside the standard mortgage measures. These are often called exceptions. That does not mean you are entitled to one. It means a lender may choose to approve some borrowers above the usual limits each year.
In practice, this can help buyers who are strong on affordability but slightly short on deposit or income multiples. However:
- exceptions are limited
- they are lender-specific
- they may be used up or applied selectively
- approval is never guaranteed
So if you are planning your purchase, it is safer to budget based on the standard rules first.
What counts as your deposit?
Your deposit usually comes from one or more of the following:
- regular savings
- a gift from family
- inheritance
- proceeds from the sale of another property
- in some cases, other provable funds accepted by the lender
Lenders will normally want a clear paper trail showing where the money came from. If part of your deposit is gifted, the bank will usually ask for written confirmation that it is a genuine gift and not a loan that must be repaid.
This is one reason buyers should avoid moving large unexplained sums into their account shortly before applying.
The real question: how much cash do you need upfront?
The deposit is the biggest upfront cost, but it is not the only one. Buyers in Ireland should also budget for:
- stamp duty
- solicitor’s fees and outlays
- valuation fee
- survey or engineer’s report if you choose to get one
- moving costs
- possible mortgage protection and home insurance setup costs
If you spend every euro on the deposit, you may leave yourself too tight for the purchase to complete smoothly.
A simple example
Let’s say you are a first-time buyer purchasing at about €300,000.
You may need roughly:
- Deposit at 10%: about €30,000
- Stamp duty and legal/professional costs: extra cash on top
The exact total will vary, but many buyers find they need more than just the headline deposit before they are truly ready.
Do you need a deposit before viewing homes?
No, but you should know your likely budget.
Before you get emotionally attached to a property, it helps to work out:
- your available deposit
- your likely borrowing capacity
- your monthly repayment comfort level
- your extra purchase costs
This gives you a realistic search range and helps you act faster when you find the right place.
If you are browsing privately listed properties, tools that help you Get matched with homes can save time by narrowing the search to homes within your realistic budget.
Why asking price and mortgage valuation are not always the same
Another point buyers often miss: your mortgage is usually based on the lower of the purchase price or the lender’s valuation.
So if you agree to pay more than the valuer thinks the property is worth, you may need to fund the difference yourself.
Example:
- Agreed price: €360,000
- Bank valuation: €350,000
- First-time buyer max lending at 90% of valuation: about €315,000
In that scenario, your required cash contribution may be more than a simple 10% of the agreed purchase price.
This is especially important in competitive areas where bidding pushes prices up quickly.
How to sanity-check the price before you offer
Before making an offer, check comparable sold prices and wider price trends.
Two useful places to start are:
- the Residential Property Price Register for past sale prices
- the CSO Residential Property Price Index for broader market direction
Neither will tell you exactly what a specific home is worth today, but together they can help you judge whether the asking price looks broadly in line with the local market.
If you are buying in a city where competition is stronger, local supply matters too. You can browse Homes for sale by owner in Dublin or Homes for sale by owner in Cork to compare what is currently on the market in similar areas.
What if you are trading up or buying after selling?
If you already own a home, your deposit may come partly from the equity released when you sell. But remember that the standard rule for second and subsequent owner-occupier buyers is generally a 20% deposit.
That can come as a surprise to movers who assume the first-time buyer rules still apply.
If you are both selling and buying, timing matters. Talk to your solicitor early about how sale proceeds, booking deposits, and completion dates may line up.
Does Local Property Tax affect mortgage approval?
Not directly as a deposit rule, but it still matters.
When buying a home, you should check the Local Property Tax position for the property and understand the ongoing ownership costs. Lenders are focused mainly on mortgage affordability, but buyers need to look at the total monthly cost of owning the home, not just the loan repayment.
What about BER and running costs?
In Ireland, residential property ads should include BER information when required. That matters for buyers because the deposit is only the start of the financial picture.
A cheaper home with a poor energy rating may need significant spending after purchase. A more efficient home may cost more upfront but less to run.
So when working out how much cash you need, include a buffer for:
- immediate repairs
- heating system upgrades
- insulation or efficiency works
- furnishing and appliances
A practical deposit checklist for Irish buyers
Before you start bidding, try to have these points clear:
1. Know your buyer status
Are you:
- a first-time buyer
- a second/subsequent buyer
- a buy-to-let investor
This affects your likely deposit requirement.
2. Confirm your usable savings
Count only money that is:
- genuinely available
- easy to evidence
- not needed for other essential costs
3. Keep extra funds aside
Do not leave yourself with only the minimum deposit. Legal and purchase costs still need to be paid.
4. Check local sold prices
Use the Property Price Register and wider CSO data to pressure-test the price before offering.
5. Be realistic about lender exceptions
Treat any exception as a bonus, not the plan.
6. Consider total monthly ownership cost
Think beyond the mortgage repayment to insurance, tax, utilities, maintenance, and BER-related running costs.
Final thoughts
For most buyers in Ireland in 2026, the starting point is straightforward:
- first-time buyers usually need about 10%
- second and subsequent home buyers usually need about 20%
- buy-to-let buyers usually need about 30%
But the genuinely useful answer is this: you need more than the bare minimum deposit to buy with confidence.
You also need to account for income limits, legal costs, valuation risk, and the real cost of owning the property after you get the keys.
