Learn how much you can borrow for a mortgage and exceptions that apply
Key Points:
- First-time buyers can typically borrow up to 4 times their gross annual income, while second-time buyers are generally limited to 5 times income.
- Most buyers need a 10% deposit, but the total property price you can afford depends on both your borrowing cap and the deposit you have available.
- Some applicants may qualify for mortgage exceptions, which can increase borrowing to as much as 75 times income for first-time buyers and 4.5 times for second-time buyers.
- Variable income such as overtime, bonuses, and commission can significantly affect borrowing power, but each lender assesses this income differently.
- Government supports like Help to Buy and the First Home Scheme can help bridge affordability gaps, while all lenders still apply affordability and stress tests before approval.
Borrowing limits based on our gross salary
One of the first questions we get asked at JC Mortgages is simple: “What’s the absolute maximum I can borrow?”
It’s the most important number in your property journey. It dictates whether you are looking at a semi-detached in the suburbs or an apartment in the city. But the answer isn’t always a simple calculator figure.
The Answer:
- First-Time Buyers can typically borrow up to 4 times their gross annual income.
- Second-Time Buyers (Movers) are generally capped at 3.5 times their income.
- Switches / Remortgaging the income limits generally do not apply in the same strict way.
However, as mortgage brokers who deal with mortgage lenders every day, we know the “official” rules are just the starting point. Between exceptions, variable income allowances, and schemes like the First Home Scheme, the final figure can vary significantly depending on who you apply with.
The “Golden Rules” of Borrowing (Loan-to-Income)
The Central Bank of Ireland sets limits on how much banks can lend to protect the economy. These are known as Loan-to-Income (LTI) caps. Here is exactly how the numbers work for every type of buyer.
First Time Buyers (FTB)
- Mortgage borrowing Limit: 4 x your gross annual income.
- The Deposit: You need a 10% deposit (90% Loan-to-Value).
First Time Buyers Maximum Borrowing Caps by Salary
The table below illustrates the standard maximum borrowing capacity for first-time buyers across different income levels, assuming the baseline 10% deposit requirement is met:
| Gross Annual Salary / Combined Income | Standard Borrowing Limit (4x Gross Salary) | Minimum 10% Deposit Required | Maximum Property Purchase Price |
|---|---|---|---|
| €50,000 (Single) | €200,000 | €22,222 | €222,222 |
| €70,000 (Single) | €280,000 | €31,111 | €311,111 |
| €90,000 (Joint) | €360,000 | €40,000 | €400,000 |
| €110,000 (Joint) | €440,000 | €48,888 | €488,888 |
| €130,000 (Joint) | €520,000 | €57,777 | €577,777 |
Second-Time Buyers
- Mortgage borrowing Limit: 3.5 x your gross annual income.
- The Deposit: You need a 10% deposit (90% Loan-to-Value) – this rule was relaxed in 2023, reducing the requirement from the previous 20%.
First Time Buyers Maximum Borrowing Caps by Salary
The table below illustrates the standard maximum borrowing capacity across various single and joint gross salary structures before any lender exceptions are applied for second time buyers:
| Gross Annual Salary / Combined Income | Standard Borrowing Limit (3.5x Gross Salary) | Minimum 10% Deposit Required | Maximum Property Purchase Price |
|---|---|---|---|
| €80,000 (Single) | €280,000 | €31,111 | €311,111 |
| €100,000 (Joint) | €350,000 | €38,888 | €388,888 |
| €120,000 (Joint) | €420,000 | €46,666 | €466,666 |
| €150,000 (Joint) | €525,000 | €58,333 | €583,333 |
Mortgage Switchers and Remortgages
The most critical factor for anyone changing lenders is that standard Central Bank mortgage lending rules do not apply to straight switchers. If you are moving an identical outstanding loan balance from Bank A to Bank B to secure a better rate, you are exempt from:
- The standard Loan-to-Income (LTI) limits (the 4x salary rule for first-time buyers or 3.5x for second-time buyers).
- The standard Loan-to-Value (LTV) minimum equity requirements.
Crucial Distinction: While the Central Bank rules do not block you, the individual retail bank you want to switch to will still run its own internal credit checks, affordability calculations, and stress tests to ensure you can comfortably meet the repayments.
The “Secret Menu”: Mortgage Exceptions
You may have heard friends say, “I got 4.5 times my salary.” This is what is known as an exception. Lenders are allowed to break the rules for a small percentage of their customers.
The exception limits are:
- First-Time Buyers: Can potentially borrow up to 75 x income.
- Second-Time Buyers: Can potentially borrow up to 5 x income.
Will I get a mortgage exception?
Banks don’t hand these out easily. To qualify, you generally need:
- Higher than average income (often €60k+ for singles, €100k+ for couples).
- A “clean” financial record (no missed payments, no gambling transactions).
- A strong savings habit.
Broker Note: Not all banks release exceptions at the same time. Some run out by June; others save them for later in the year.
Variable Income: Your “Hidden” Borrowing Power
This is the biggest gap we see in online calculators. If you earn a base salary of €50,000 but make another €10,000 in overtime, commission, or bonuses, how is that calculated?
- Bank A might ignore your overtime entirely.
- Bank B might take 50% of your average bonus.
- Bank C might take 100% of your guaranteed overtime.
This can swing your borrowing power by €40,000 or more.
Never assume your borrowing limit based on your basic salary alone. Let us assess your payslips to see which lender treats your variable income most favourably.
Bridging the Gap: Government Schemes
If the Central Bank of Ireland’s rules don’t give you enough to buy the home you want, two government schemes can essentially “top up” your budget.
| Help to Buy (HTB Scheme) | First Home Scheme (FHS) |
|---|---|
| This is a tax refund of up to €30,000. | The government takes an equity share in your new build home (up to 30%). |
| Impact: The HTB scheme does not increase your borrowing limit (the loan itself), but it increases your deposit. This reduces the mortgage amount you need, making the 4 x limit easier to fit into. | Impact: If the bank lends you €300,000 but the house costs €400,000, the FHS can provide the missing €100,000 (subject to criteria). |

Summary Table: Maximum Mortgage Borrowing Amount
| Buyer Type | Standard Income Cap | Min. Deposit Required | Maximum Property Purchase Price |
|---|---|---|---|
| First-Time Buyer | 4 x Income | 4.75 x Income | 10% |
| Second-Time Buyer | 3.5 x Income | 4.5 x Income | 10% |
| Fresh Start* | 4 x Income | 4.75 x Income | 10% |
| Buy-to-Let Investor | Varies (Rent coverage) | N/A | 30% |
*Fresh Start: Applicants who are divorced, separated, or have gone through insolvency may be treated as First-Time Buyers again.
The “Stress Test”: Can you afford to pay your mortgage?
Regardless of the mortgage borrowing rules, every bank performs a Stress Test. They check if you could still afford your mortgage if interest rates rose by 2% above the current rate.
If you have high childcare costs, expensive car loans, or credit card debt, the bank may lend you less than 4 x your income to ensure you pass this stress test.
Top Tip: Clear short-term debt (like car loans) before applying. It often boosts your borrowing capacity significantly more than the value of the loan itself.
Mortgage Borrowing Amount – FAQs
While payslips prove you have cash flow, they do not verify the sustainability of your income. A Salary Certificate is a specific, mandatory document that must be signed and stamped by your employer. It confirms your employment status (e.g., permanent vs. probation) and explicitly separates guaranteed salary from variable income (overtime/bonuses). Lenders require this to apply the correct risk weighting to your earnings.
Not necessarily. While three years was the traditional standard, many lenders in 2025 accept two years of certified accounts, Revenue Form 11s, and Chapter 4 receipts. Lenders typically assess your borrowing capacity based on the average net profit of these two years. However, if your most recent year shows a decline in profit, they may base their offer solely on that lower figure.
Lenders are legally required to check the CCR for any loan application. The register records details of all loans of €500 or more, including credit cards, overdrafts, and personal loans. It does not provide a “credit score” but displays a factual history of your repayments. Any active loans found here will be deducted from your net disposable income, directly reducing the maximum mortgage amount you can borrow.
Once you submit a full documentation pack, securing an Approval in Principle (AIP) typically takes 5 to 10 working days. This approval is generally valid for 6 months, giving you a window to find a property. Once you go “Sale Agreed,” progressing to a full formal Loan Offer (which requires a property valuation) can take an additional 2 to 4 weeks.
