The question “how much mortgage can I get in Ireland?” is the starting point for every homebuyer. The answer determines which properties you can realistically view, where you can afford to buy, and how much deposit you need to save. In Ireland, mortgage borrowing is strictly regulated by the Central Bank, which sets clear limits on how much lenders can offer you.
This guide explains exactly how much you can borrow based on your income, what deposit you’ll need, and how affordability calculations work in practice. We’ll walk through real examples for different salary levels and explain when you might qualify for an exception to standard rules.
The 3.5x Income Rule: Ireland’s Core Borrowing Limit
The Central Bank of Ireland’s mortgage measures, introduced in 2015 and refined over subsequent years, set a maximum loan-to-income (LTI) ratio of 3.5 times your gross annual income. This is the foundation of how much you can borrow.
Your gross income means your salary before tax, PRSI, and USC deductions. If you earn €50,000 per year before deductions, your maximum mortgage is €175,000 (50,000 × 3.5).
For joint applications, lenders add both incomes together first, then apply the multiplier. Two borrowers each earning €40,000 have a combined income of €80,000, so can borrow up to €280,000.
This income multiple is a hard limit for the vast majority of mortgages. Irish lenders cannot routinely exceed it — they’re only permitted to grant exceptions in specific circumstances, which we’ll cover below.
What Income Counts?
Lenders assess your gross basic salary as the primary income source. Beyond that, they’ll consider:
- Overtime: If you’ve received consistent overtime for at least two years, lenders typically include 50-100% of the average amount
- Bonuses: Regular contractual bonuses may be included, usually averaged over 2-3 years
- Commission: Sales commission is assessed similarly to bonuses, with lenders taking a conservative average
- Rental income: Income from investment properties may be included, though lenders typically apply a discount (often 75% or 80% of actual rent)
- Second jobs: Regular additional employment income can count if well-documented
What doesn’t count: child benefit, one-off bonuses, irregular income, or income you expect to receive but haven’t yet earned.
For self-employed applicants, lenders examine your last two or three years of accounts. They typically use either an average of these years or the most recent year’s profit, whichever is lower. This means self-employed borrowers need comprehensive documentation and consistent earnings history.
Deposit Requirements and Loan-to-Value Limits
The Central Bank doesn’t just limit how much you can borrow relative to income — it also sets minimum deposit requirements based on the property value. These are called loan-to-value (LTV) limits.
First-time buyers can borrow up to 90% of the property value, meaning you need a 10% deposit. On a €300,000 home, that’s a €30,000 deposit and a maximum mortgage of €270,000.
Second and subsequent buyers can borrow up to 80% of the property value, requiring a 20% deposit. The same €300,000 property would need a €60,000 deposit, with a maximum mortgage of €240,000.
These LTV limits apply regardless of your income. Even if your income would allow you to borrow €350,000, you can’t get a €350,000 mortgage on a €300,000 property — you’re capped at the property value minus your minimum deposit.
How Much Property Can You Actually Buy?
Your actual purchasing power combines the income multiple and deposit requirement. Here’s the calculation:
If you can borrow €280,000 (based on 3.5x income) and you’re a first-time buyer with a 10% deposit requirement, you can afford a property worth up to approximately €311,000. That’s your maximum mortgage (€280,000) divided by 0.9 (since you can borrow 90%).
The formula: Maximum mortgage ÷ (1 - deposit requirement as decimal) = Maximum property value
For a second-time buyer with the same €280,000 borrowing capacity but needing a 20% deposit, the maximum property value drops to €350,000 (€280,000 ÷ 0.8).
Worked Examples: Different Salary Levels
Let’s look at concrete examples for different income scenarios.
Single Person, First-Time Buyer
Gross income: €45,000
Maximum mortgage: €157,500 (45,000 × 3.5)
Deposit required: 10%
Maximum property price: €175,000
Deposit needed: €17,500
This buyer needs to save €17,500 and can look at properties up to €175,000. After the deposit, they borrow €157,500.
Single Person, Second-Time Buyer
Gross income: €45,000
Maximum mortgage: €157,500
Deposit required: 20%
Maximum property price: €196,875
Deposit needed: €39,375
The same income level gets you less purchasing power as a second-time buyer because you need a larger deposit. The mortgage amount is the same, but you can afford a slightly higher property price because your deposit contribution is bigger.
Couple, First-Time Buyers
Combined gross income: €80,000 (€40,000 + €40,000)
Maximum mortgage: €280,000 (80,000 × 3.5)
Deposit required: 10%
Maximum property price: €311,111
Deposit needed: €31,111
Two average salaries combined open up substantially more options. This couple can target properties in the €280,000-€310,000 range with a deposit just over €30,000.
High Earner, Second-Time Buyer
Gross income: €75,000
Maximum mortgage: €262,500 (75,000 × 3.5)
Deposit required: 20%
Maximum property price: €328,125
Deposit needed: €65,625
A higher earner faces the challenge of saving a larger deposit. Even with substantial income, the 20% deposit requirement means saving €65,000+ before you can purchase.
Lender Exceptions: Borrowing Above 3.5x Income
The Central Bank allows Irish lenders to grant exceptions to the 3.5x income limit, but these are strictly controlled by quota.
First-time buyers: Up to 20% of the value of first-time buyer mortgages drawn down in a calendar year can exceed 3.5x income. In practice, this means roughly one in five first-time buyer mortgages can be granted at higher multiples, typically 4x income.
Second and subsequent buyers: Only 10% of these mortgages can exceed the income limit.
Exceptions typically go to:
- Borrowers in high-cost areas (Dublin, Cork city centres) where 3.5x income doesn’t match property prices
- High earners with strong credit histories and substantial deposits
- Applicants who can demonstrate exceptional affordability
You cannot rely on getting an exception. Banks prioritise applicants who are closest to approval and have the strongest applications. If you’re depending on 4x income to afford a property, you’re taking a significant risk that your mortgage may not be approved.
Lender exceptions also don’t override LTV limits. You still need your 10% or 20% deposit regardless of income multiple.
Affordability: The Other Half of the Equation
Meeting the income multiple and having your deposit doesn’t automatically guarantee mortgage approval. Lenders must also assess affordability — your ability to make monthly repayments both now and if interest rates rise.
Irish lenders conduct stress tests. They calculate whether you could still afford repayments if interest rates increased by 2% above the current rate. If your disposable income after meeting the higher repayments would be too tight, they may reduce the amount they’ll lend you, even if it’s below 3.5x income.
Monthly Commitments That Reduce Borrowing
Lenders examine all your monthly financial commitments:
- Car loans and personal loans
- Credit card balances (even if you pay them off monthly)
- Childcare costs
- Existing mortgages or investment property loans
- Regular maintenance payments or financial support obligations
High monthly commitments reduce your affordability. Someone earning €60,000 with no debts will borrow more than someone earning €60,000 with a €400 monthly car loan and €200 in credit card payments.
Typical Monthly Repayment Calculations
As a rough guide for 2026 (with rates around 3.5-4% for fixed terms):
| Mortgage Amount | Monthly Repayment (25 years, 3.75%) | Annual Cost |
|---|---|---|
| €150,000 | €770 | €9,240 |
| €200,000 | €1,027 | €12,324 |
| €250,000 | €1,284 | €15,408 |
| €300,000 | €1,541 | €18,492 |
| €350,000 | €1,797 | €21,564 |
Lenders typically want your mortgage repayment to be no more than 35% of your net (take-home) income. If you earn €50,000 gross (approximately €3,200 net per month), a €1,100 monthly repayment would be about 34% of net income — right at the upper limit of what most lenders accept.
Comparing Irish Lenders: Who Offers Most?
While all Irish lenders must follow Central Bank rules, they differ in how they assess income and affordability. Some are more generous with overtime or bonus inclusion; others are stricter on debt commitments.
High-Level Lender Comparison
| Lender Feature | More Generous Approach | Stricter Approach |
|---|---|---|
| Overtime income | Include 100% of 2-year average | Include 50% only |
| Bonus income | Accept 1-year recent bonuses | Require 3-year history |
| Self-employed | Consider most recent year | Average 2-3 years, take lower |
| Credit history | Minor issues overlooked | Zero tolerance for missed payments |
| Exceptions | Willing to use exception quota | Reserve exceptions for exceptional cases |
AIB, Bank of Ireland, and Permanent TSB are the largest lenders and generally compete strongly on rates and lending criteria. Haven, Avant Money, and Finance Ireland can sometimes be more flexible on exceptions or income assessment. Credit unions may have different approaches entirely for smaller mortgage amounts.
Working with a mortgage broker gives you access to multiple lenders simultaneously, and brokers know which lender is most likely to approve your specific situation.
Special Circumstances: Non-Standard Applications
Self-Employed Borrowers
Self-employed applicants face additional documentation requirements. You’ll need:
- Two to three years of certified accounts (signed by an accountant)
- Tax returns and tax clearance certificate
- Evidence of business continuity and stability
Lenders assess self-employed income conservatively. If your profit was €50,000, €55,000, and €60,000 over three years, they might use €50,000 or an average of €55,000, then apply the 3.5x multiplier. This means your maximum mortgage could be €175,000-€192,500.
Contract Workers
Contractors earning via limited companies face similar scrutiny to self-employed borrowers. Those on fixed-term employment contracts (e.g., 12-month contracts) can often be treated as PAYE employees if they have contract history and renewal likelihood.
Single Parents and Separated Applicants
Maintenance payments you receive can sometimes be included as income (typically if they’re court-ordered and have a long remaining duration). Maintenance you pay reduces your affordability. Childcare costs are factored as monthly commitments, which can significantly impact what you can borrow.
Applicants with Credit Issues
Missed loan or credit card payments in the past 12 months will cause problems. Most lenders reject applications outright if you have recent arrears. Older credit issues (2+ years ago) may be overlooked if your current credit conduct is perfect.
County Court Judgements (CCJs) or debt settlements remain on your record for five years in Ireland and will typically prevent mortgage approval during that time.
The Help to Buy Scheme and First Home Scheme
First-time buyers have access to two government support schemes that can increase purchasing power.
Help to Buy provides a tax rebate of up to 10% of the property value (maximum €30,000) for new builds. This rebate can be used as part of your deposit, effectively reducing the cash you need upfront. However, you still need to demonstrate you can afford the property, and the rebate doesn’t increase your 3.5x income limit.
First Home Scheme is a shared equity scheme where the government takes an equity stake in your property (up to 30% for new builds, 20% for older properties, with higher percentages in certain areas). This reduces your mortgage requirement. If you’re buying a €300,000 property with 30% government equity, you only need a mortgage for €210,000, making it accessible on a lower income.
The First Home Scheme has maximum property price limits (€325,000-€500,000 depending on location and property type) and income limits (€70,000 for a single applicant, €100,000 for joint applicants).
Practical Steps: Calculating Your Mortgage Capacity
- Calculate gross income: Add up your total annual gross salary including reliable overtime or bonus
- Multiply by 3.5: This is your maximum mortgage under Central Bank rules
- Determine buyer status: First-time (10% deposit) or second-time (20% deposit)
- Calculate maximum property price: Divide your maximum mortgage by 0.9 (first-time) or 0.8 (second-time)
- Calculate deposit needed: Subtract maximum mortgage from maximum property price
- Stress test affordability: Use a mortgage calculator with current rates plus 2% to check monthly repayments fit your budget
Before viewing properties, get a mortgage approval in principle. This confirms exactly how much a lender will offer you based on a full assessment of your income, debts, and credit history. An AIP is valid for six months and makes you a serious buyer when you find the right property.
What If You Can’t Borrow Enough?
If the 3.5x rule means you can’t afford properties in your target area, you have several options:
Increase your income: A pay rise, promotion, or taking on additional work all increase your borrowing capacity directly
Buy with a partner or family member: Joint applications combine incomes, dramatically increasing what you can borrow
Save a larger deposit: This doesn’t increase your mortgage amount, but it increases the property price you can afford
