Understand the minimum mortgage deposit rules and hidden closing costs
Key Points:
The 10% Rule: Under Central Bank rules, the minimum mortgage deposit in Ireland is 10% of the property purchase price for both first-time and second-time buyers.
The “Real” Cash Target: While the deposit is 10%, you actually need 12% to 13% in total cash to successfully close a property purchase.
Essential Hidden Costs: You must save separate cash to cover non-mortgageable legal fees, valuation fees, and Stamp Duty (which is 1% of the property value).
The New-Build Buffer: If buying a new build, you need extra cash on hand for “grey box” expenses like flooring, appliances, and blinds that cannot be added to the loan.
State Help Available: If you are a first-time buyer purchasing a new build, government schemes like Help to Buy (HTB) can provide up to €30,000 directly toward your first-time buyer deposit in Ireland.
Central Bank Rules: What Is the Minimum Mortgage Deposit in Ireland?
When clients ask us, “How much do I need for a mortgage deposit?”, they usually expect a simple percentage. The short answer is that you generally need a 10% deposit of the property’s purchase price, regardless of whether you are a first-time buyer or second-time buyer (moving home). However, the real answer involves more than just the deposit. To safely close a sale in Ireland’s current market, you actually need approximately 12% to 13% of the purchase price in accessible funds. This covers your regulatory 10% deposit plus the “hidden” costs of stamp duty, legal fees, valuations, and surveys, all of which must be paid before you get the keys.
In this guide, we look beyond the basic percentages to calculate the total cash you need for your deposit and to buy a home in Ireland, breaking down the costs for first-time buyers, trader-uppers, and switchers (remortgaging / refinancing).
Mortgage Deposit Ireland – Go To:
Deposit core requirements: The 10% rule
The Central Bank of Ireland’s macroprudential rules are the starting point for every mortgage journey. These rules dictate the minimum “skin in the game” a buyer must have.
First Time Buyers (FTBs)
As a first-time buyer, you can borrow up to 4 times your gross annual income, but you are capped at 90% financing. This means you must provide the remaining 10% upfront.
Government Help: Ideally, if you are buying a new build, the Help to Buy (HTB) scheme can cover up to €30,000 of this requirement , meaning your actual cash contribution could be significantly lower.
Second Time (Trader Uppers)
A significant recent change has levelled the playing field for second-time buyers. Previously, you often needed a 20% deposit. Now, second-time buyers also only require a 10% deposit.
Income Limit: The borrowing limit for this group is typically 5 times gross annual income, though exceptions are possible.
Remortgage / Switchers
If you are refinancing (switching lender), you generally do not need a cash deposit. Instead, you need equity.
The 90% Rule: Most lenders will allow you to switch as long as you have at least 10% equity in your home (i.e., your mortgage balance is 90% or less of the home’s current value).
Mortgage Deposit: Real World Examples - What you Actually Pay
To make this concrete, let’s look at three typical scenarios we see at JC Mortgages.
Example 1: The First-Time Buyer (New Build)
- Scenario: Sarah and Paul are buying a new build home in Kildare for €400,000.
- Deposit Needed (10%): €40,000.
- Source of Funds: They qualify for the maximum Help to Buy rebate of €30,000.
- Cash Savings Needed: They only need €10,000 of their own savings to complete the 10% deposit.
Note: They will still need cash for Stamp Duty and fees (outlined below).
Example 2: The Second-Time Buyer (Trading Up)
- Scenario: The Murphy family is selling their apartment for €300,000 (with €100,000 mortgage remaining) and buying a larger house for €550,000.
- Deposit Needed (10%): €55,000.
- Source of Funds: They have €200,000 in equity from their sale (€300k value – €100k loan).
- Cash Savings Needed: The 10% deposit €55,000, while they will have the equity in the home they would need 10% to cover the deposit, before they get the sale proceeds. This may need a gift if trying to sell their existing home and buy at the same time.
Example 3: Remortgaging (The Switcher)
- Scenario: John bought his home 5 years ago. It is now worth €350,000 and he owes €250,000.
- LTV Ratio (loan to value): 71% (He owns 29% of the home).
- Deposit Needed:
- Cost to Switch: Approximately €1,500 in legal and valuation fees.
- Benefit: Most lenders offer “cashback” (often €2,000 – €3,000). John effectively switches for free to get a lower interest rate.
Most online calculators stop at the deposit. However, you cannot complete a sale without paying the following transactional costs. You need these funds to be liquid (available in cash) before the sale closes.
| Addition to Deposit | Description | Cost |
|---|---|---|
| Stamp Duty | This is a government tax charged at 1% of the property value (up to €1 million) | On a €400,000 home: €4,000 |
| Legal Fees | Solicitor fees vary, but you should budget for professional fees plus VAT (23%) and “outlays” (Land Registry fees, search fees, etc.) | Estimated Cost: €2,500 – €3,000 |
| Valuation | Required by the lender to confirm the property price | Approx. €150 – €200 |
| Survey | Highly recommended for second-hand homes to check for structural issues (damp, subsidence) | Approx. €500 – €1,000 |
Often Overlooked: The “Grey Box” Reality of New Builds
Often overlooked is the cost of turning a house into a home. If you are buying a new build, you are essentially buying a “grey box.” It will likely come with painted walls and a kitchen, but no flooring and no window treatments.
You need to keep cash back for this. You cannot add these costs to your mortgage.
- Flooring (100 sq m house): Laminate/Carpets @ €50/sq m = €5,000.
- Blinds/Curtains: €1,500 – €3,000.
- Appliances: If not included, budget €2,500.
- Moving Costs: Professional movers for a 3-bed house typically charge €1,200 – €2,000.
Pro Tip: Do not spend your last euro on the deposit. Lenders like to see a “buffer” in your accounts to ensure you can afford these post-purchase expenses without taking out a personal loan (which could jeopardise your mortgage drawdown).
Timeline: When Do I Pay?
Understanding ‘when’ money leaves your account is just as important as ‘how much’.
| Payment Stage | Amont | Who Gets It | Refundable? |
|---|---|---|---|
| Sale Agreed | Booking deposit (approx. €5k – €10k) | Estate Agent | Yes, fully |
| Contract Signing | Contract deposit (balance of 10%) | Your Solicitor | No (binding) |
| Closing Day | Stamp Duty & Legal Fees | Your Solicitor | Non applicable |
| Post-Closing | Movers & Furniture | Suppliers | Non applicable |
Note: The Booking Deposit is part of your 10% total, not extra. If you pay €5,000 to the agent, you pay the remaining balance to your solicitor later.
Summary: Your Total “Cash to Close”
For a standard €350,000 Second-Hand Home:
- Mortgage Deposit (10%): €35,000
- Stamp Duty (1%): €3,500
- Solicitor & Outlays: €3,000
- Survey & Valuation: €800
- Immediate Furnishing/Moving: €3,000
- TOTAL CASH NEEDED: €45,300 (approx 13% of price)
Mortgage Deposit FAQs
No. Central Bank rules generally prohibit using borrowed funds (like a personal loan) for your deposit. Lenders will check your credit history and bank statements. If they see a recent loan drawdown used for the deposit, the mortgage application will likely be declined.
Yes. For eligible first-time buyers purchasing a new build, the Help to Buy (HTB) rebate is paid directly to the developer. This reduces the cash amount you need to hand over. If your HTB rebate is €30,000 and your required deposit is €40,000, you only need to transfer €10,000 yourself.
Yes. The booking deposit paid to the estate agent when you go “Sale Agreed” is fully refundable until you sign the contracts. If your survey reveals an issue or your finance falls through before signing contracts, you get this money back.
Not anymore. The Central Bank rules were updated recently. Second and subsequent buyers (trader-uppers) now generally only need a 10% deposit, the same as first-time buyers. The main difference is the borrowing limit (3.5 times income for second-time buyers vs. 4 times for first-time buyers).
Legal fees vary, but for a standard purchase, you should budget between €2,500 and €3,000. This includes the solicitor’s professional fee plus VAT (23%) and necessary “outlays” like Land Registry fees and search fees. Always ask for a quote that is “inclusive of VAT and outlays” to avoid surprises.
