The Central Bank of Ireland caps how much first-time buyers can borrow at 4 times their gross annual income. Beyond that ceiling, loan-to-value rules demand a 10% deposit — meaning both limits must be met before a lender will approve a mortgage.

What is the maximum mortgage borrow limit in Ireland?
The Central Bank of Ireland sets two hard caps that determine how much you can borrow: Loan-to-Income (LTI) and Loan-to-Value (LTV). These apply to all regulated mortgage lenders across the Republic of Ireland. LTI limits how much you can borrow relative to your salary, while LTV caps the loan as a percentage of the property price.
Central Bank rules on income multiples
For first-time buyers, the LTI ceiling sits at 4 times your gross annual income. That means a single buyer earning €50,000 gross could theoretically borrow up to €200,000 on income alone. A couple with a combined €100,000 gross income could reach €400,000 under this rule (Central Bank of Ireland). Second and subsequent buyers face a slightly lower ceiling of 3.5 times income. The Central Bank explains that these measures exist to ensure prudent lending and protect borrowers from overcommitting.
Crucially, lenders can exceed these limits for a small portion of their mortgage book. Up to 15% of first-time buyer lending and 15% of second/subsequent buyer lending can breach the standard LTI ceiling (Central Bank of Ireland). This flexibility exists to handle genuine edge cases — a buyer with an unusually large deposit or exceptional circumstances — but it doesn’t mean the limits are soft. Most borrowers planning a standard purchase should work within the 4× rule.
Loan to value caps
The LTV limit requires residential buyers to fund at least 10% of the purchase price themselves. For a €300,000 home, that means a minimum €30,000 deposit — leaving the lender to cover the remaining €270,000. Buy-to-let investors face a steeper requirement: they must fund 30% of the purchase price themselves, meaning only 70% LTV applies to investment properties (Central Bank of Ireland). LTI limits do not apply to buy-to-let, switcher, or lifetime mortgages under the current framework.
A first-time buyer couple on €90,000 combined gross can borrow up to €360,000 under the LTI rule. Both limits must be satisfied simultaneously.
What can I borrow on a 30k salary?
A single person on €30,000 gross annual income faces a straightforward calculation under Central Bank rules: 4× the gross income equals €120,000 maximum under the LTI cap. But that’s not the whole picture. Lenders also run their own affordability checks beyond the Central Bank minimums, examining your monthly income against existing debt repayments, living expenses, and the interest rate applied to your mortgage (JC Mortgages).
Example calculations
For a €120,000 mortgage over 30 years at an interest rate of 4%, monthly repayments hover around €573. If rates climb to 5%, that figure rises to approximately €644. Online calculators from EBS, AIB, and Bank of Ireland let you input your salary, existing commitments, and loan term to see where you land. These tools are useful starting points but they provide estimates, not loan offers.
Factors affecting borrow amount
Beyond the headline salary multiple, lenders factor in your complete financial picture. Bonuses and irregular income can partially count — 50% of the average non-guaranteed income over three years can be included in your gross income calculation (Mortgages.ie). Existing loan repayments, car financing, and child maintenance reduce the amount a lender considers you can afford monthly. Credit history also plays a role: missed payments or default markers are signals that lenders treat as red flags in a mortgage application.
How much is a 300k mortgage per month in Ireland?
A €300,000 mortgage requires meeting both the LTI and LTV thresholds. Under LTI alone, a borrower needs roughly €75,000 in gross annual income to support a €300,000 loan at the 4× multiple. Under LTV, a 10% deposit (€33,333) on a €333,333 property is required alongside the €300,000 loan. Monthly repayments on €300,000 depend heavily on the term length and interest rate applied.
Repayment examples
Borrowers can choose between shorter terms with higher monthly payments or longer terms with lower payments. A 20-year term at 4% interest results in monthly repayments of approximately €1,818. Extend that to 30 years and the payment drops to roughly €1,432 at the same rate. The Switcher.ie calculator allows you to model these scenarios with different term lengths. The longer you stretch the loan, the more you pay in total interest over its lifetime.
Interest rate impact
Interest rates directly determine what you can actually borrow for a given monthly payment. As of early 2026, Irish mortgage rates remain elevated compared to the eurozone average. A borrower comfortable with a €1,500 monthly payment at 4% could service roughly €313,000 over 30 years. At 5%, that same payment covers approximately €279,000 — a difference of €34,000 on the same income constraints. Bonkers.ie confirms that LTI rules apply regardless of income level, but the practical borrowing amount varies with prevailing rates.
What is the minimum salary for a 300k mortgage?
Working backwards from a €300,000 mortgage, the minimum gross annual income depends on which cap bites first. Under the 4× LTI rule, you need approximately €75,000 gross per year — or you could apply with a partner whose income pushes the combined total to that threshold. If your income falls short, a larger deposit reduces the required loan size and may bring your monthly payment within affordability limits.
Income requirements
The Central Bank’s LTI limits apply to your gross income before tax and national insurance contributions. Net (take-home) pay is not the relevant figure for these calculations. Lenders examine your payslips to establish gross annual income and may average figures if you receive regular overtime or bonuses. For self-employed applicants, lenders typically look at two to three years of audited accounts to establish an income figure.
Second applicant boosts borrowing power
Adding a second applicant to your mortgage application can significantly increase your borrowing capacity. Where one applicant earns €40,000 gross, the maximum single-applicant LTI borrow is €160,000. Adding a second earner at the same income level doubles the combined gross to €80,000 and pushes the 4× cap to €320,000 — comfortably covering a €300,000 mortgage. This is a common strategy for single applicants wondering whether they can qualify alone.
A second applicant’s income is helpful, but lenders also examine joint debt obligations. If the second applicant carries significant existing loans, the net benefit to your mortgage application may be smaller than the raw income multiple suggests.
Can a 70 year old get a 20 year mortgage?
Age restrictions on mortgage terms vary by lender in Ireland. While the Central Bank sets macroprudential limits on LTI and LTV, it does not impose a maximum age limit for mortgage term end dates. That decision is left to individual lenders, each applying their own policy. Most lenders in Ireland will not extend mortgage terms beyond the applicant’s retirement age, which means a 70-year-old borrower seeking a 20-year term would typically be declined on age grounds alone.
Age restrictions
The typical maximum term end age across Irish lenders falls between 65 and 70 years. Some lenders use the applicant’s expected retirement date as the ceiling, meaning a 55-year-old planning to retire at 65 would max out at a 10-year term. Switching lenders — or choosing a lender with more flexible age policies — can sometimes unlock longer terms for older applicants. Local Authority mortgages and certain specialist lenders may offer more lenient age criteria.
Retiree options
Pension income can be considered in affordability assessments, but lenders apply different treatment to pension income compared to salary. A retiree with a private pension of €30,000 gross per year could borrow up to €120,000 under the 4× LTI rule. Bridging loan products have emerged as a niche option for retirees purchasing a new home before selling their existing property — and under a targeted amendment announced 8 April 2026, principal home bridging loans are now exempt from LTI limits (Central Bank of Ireland). Bridging loans carry a maximum term of 18 months, with LTV still capped at 90% for principal homes.
Retirees seeking longer mortgage terms face a structural tension: stretching payments over 20 years reduces monthly pressure but conflicts with lenders’ term-end age policies. Lifetime mortgages, available from some specialist providers, sidestep term restrictions but typically carry higher interest rates and different risk profiles.
How many times my salary can I borrow for a mortgage Ireland?
The straightforward answer is 4 times your gross annual income if you are a first-time buyer, or 3.5 times if you are buying as a second or subsequent buyer. These are the regulatory caps set by the Central Bank of Ireland and apply uniformly across all regulated mortgage lenders. Bonkers.ie confirms this applies regardless of income level — a €200,000 earner and a €40,000 earner both face the same 4× ceiling as first-time buyers.
These multiples are not suggestions — they are hard regulatory limits for the vast majority of mortgage transactions. Up to 15% of a lender’s first-time buyer mortgage book can exceed the 4× limit, but this exemption exists for edge cases, not for borrowing. A borrower who walks into a bank expecting to borrow 5× salary will be declined under standard criteria.
Can a single person get a mortgage in Ireland?
Single applicants absolutely can get mortgages in Ireland. The Central Bank’s LTI and LTV rules apply equally to single and joint applicants. A single person on a qualifying income can borrow up to the full 4× multiple without a partner. The practical constraint for single applicants is often income level — a single earner on a modest salary may need to look at lower-priced properties or explore schemes like the First Home Scheme to bridge the affordability gap.
Lenders treat single applicants on their individual merits, examining income stability, employment type, and credit history. JC Mortgages notes that final borrowing amounts depend on lender-specific criteria beyond Central Bank rules — a lender may decline a single applicant despite meeting the LTI/LTV requirements if other affordability concerns arise.
What is a red flag in a mortgage?
Mortgage lenders in Ireland watch for several signals that can derail an application. Payment arrears history on existing credit, county court judgments (CCJs), and voluntary arrangements with creditors all appear on credit checks and raise concerns. High levels of existing debt relative to income — known as debt-to-income ratio — also flags risk. Lenders also examine employment status: probationary periods, self-employment without audited accounts, and casual or zero-hours contracts can all complicate approval.
Overborrowing relative to stated income is another risk — if your loan application asks for an amount that doesn’t align with your documented income, lenders will probe further. Large cash deposits without a clear paper trail can also prompt questions about the source of funds. Mortgages.ie advises that borrowers should present a clear, consistent financial picture to avoid triggering manual review processes that slow down approvals.
How much can I borrow from a credit union?
Credit unions in Ireland have significantly expanded their home lending capacity under updated rules that took effect on 30 September 2024. The home lending limit for credit unions increased from a combined 15% of total assets (covering both home and business lending) to 30% of total assets for home lending specifically (Gov.ie). Based on total credit union assets of approximately €22.05 billion, this change unlocked an estimated €6.6 billion in additional home lending capacity across the sector.
Credit unions are not bound by the Central Bank’s LTI/LTV rules in the same way as regulated mortgage lenders, giving them potentially more flexibility for borrowers who don’t fit standard criteria. However, each credit union sets its own lending policy, meaning borrowing limits vary from one credit union to another. The Department of Finance stated that the changes reflect the growing competence and capability of credit unions while giving them space to compete more effectively in the home lending market.
What are the mortgage measures Central Bank of Ireland?
The Central Bank’s mortgage measures are macroprudential rules introduced in 2015 and updated since then. They set limits on Loan-to-Income (LTI) ratios — how much you can borrow relative to salary — and Loan-to-Value (LTV) ratios — how much of the property price a lender can cover. The Central Bank of Ireland explains that these measures aim to control house price inflation and ensure prudent lending standards across the system.
The measures apply to all regulated mortgage lenders — banks, building societies, and non-bank lenders — creating a level playing field. Lenders that exceed the limits for more than their allowed exemption quota face regulatory consequences. Switcher.ie provides a clean summary table of LTV and LTI limits by buyer type. The system allows flexibility through exemptions while maintaining overall market stability — a balance that has drawn praise from international regulators studying Ireland’s approach.

Frequently Asked Questions
What is a red flag in a mortgage?
Lenders watch for payment arrears history, CCJs, high debt-to-income ratios, employment on probation, and large cash deposits without a clear source trail. Overborrowing relative to stated income also triggers closer scrutiny.
How much can I borrow from a credit union?
Credit unions can now lend up to 30% of their total assets for home loans following rule changes effective 30 September 2024. Each credit union sets its own lending policy, so borrowing limits vary. Credit unions are not bound by Central Bank LTI/LTV rules in the same way as banks.
What are the mortgage measures Central Bank of Ireland?
The mortgage measures are macroprudential rules that cap how much lenders can advance relative to borrower income (LTI) and property value (LTV). First-time buyers face a 4× LTI cap and 90% LTV ceiling. The measures were introduced in 2015 and updated in 2023, with a 2026 amendment covering bridging loans.
Can a 70 year old get a 20 year mortgage?
Most Irish lenders will not extend mortgage terms beyond the applicant’s expected retirement age, typically 65–70. Some lenders and specialist products offer more flexible age criteria. Lifetime mortgages are available for older borrowers but carry different terms and risks.
What is the minimum salary for a 300k mortgage?
Under the 4× LTI rule, you need approximately €75,000 gross annual income to support a €300,000 mortgage. Adding a second applicant or increasing your deposit can help bridge the gap if your income falls short of this threshold.
How much is a 300k mortgage per month in Ireland?
Monthly repayments on €300,000 depend on term and interest rate. At 4% over 30 years, expect roughly €1,432 per month. At 5% over 30 years, the figure rises to around €1,610. Use an online mortgage calculator to model your specific scenario with current rates.
For first-time buyers in Ireland, the borrowing question has a clean answer on paper: 4 times your gross salary, with a 10% deposit saved. The reality of your monthly payment, your lender’s individual affordability check, and the specific property you’re targeting all add layers that make the final number specific to your situation. Run the numbers on a lender’s calculator before you make an offer — knowing your ceiling means you shop with confidence rather than hope.
