Think about affordability in two stages: first the regulatory borrowing limits, then your own household budget. A lender's maximum approval is a ceiling, not a recommendation.
Start with the payment, not just the maximum loan
Two households with the same income can have very different affordable mortgage amounts. Existing loans, childcare, transport, savings goals and other regular spending all affect the payment a household can comfortably maintain.
Use our main calculator to test different loan sizes and rates, then compare the payment with your real monthly budget.
Understand the Central Bank limits
For standard owner-occupier lending, the current Central Bank mortgage measures generally cap borrowing at 4 times gross income for first-time buyers and 3.5 times gross income for second and subsequent buyers. The standard loan-to-value limit for both is 90%, meaning a 10% minimum deposit. Buy-to-let lending generally has a 70% LTV limit.
Lenders can use a limited allowance for some lending above the standard limits, but you should not build your budget around receiving an allowance. The lender still makes an individual credit and affordability decision.
Four constraints to check
- Income: gross income affects the regulatory LTI ceiling, but lenders assess which income they will count.
- Deposit: a larger deposit reduces the mortgage required and may improve the LTV available to you.
- Monthly affordability: the payment must fit your household budget after normal living costs and other commitments.
- Stress and lender criteria: lenders use their own assessment policies, which can mean you qualify for less than the regulatory maximum.
Stress-test the payment yourself
Do not build your budget around today's cheapest rate. Try a higher rate in the calculator and see whether the payment would still be manageable.
A useful test is to compare the payment at your expected rate with a rate that is one or two percentage points higher. This is not a lender stress test; it is simply a way to understand your own resilience.
Don't forget the costs outside the mortgage
Your deposit is not the only cash you need. Buyers can also face stamp duty, legal fees, valuation and survey costs, moving costs, repairs, furniture and insurance.
CCPC recommends budgeting for these additional costs when planning what you can afford. Keep a separate buffer rather than using every euro of available cash for the deposit.
A bigger deposit can change the picture
Suppose a property costs €350,000. A 10% deposit is €35,000, leaving a €315,000 mortgage. A €70,000 deposit would reduce the mortgage to €280,000.
A larger deposit can lower the amount borrowed and may improve your LTV, but it is not automatically best to put every available euro into the property. You still need cash for buying costs and emergencies.
What if you are buying with someone else?
For joint applicants, the relevant income can be combined for the Central Bank's LTI framework, subject to the lender's assessment of the income. The same principle applies: the maximum theoretical loan is not the same as a comfortable household budget.
FAQ
How much mortgage can I afford in Ireland?
There is no single percentage that works for every household. Work backwards from your actual essential spending, savings goals and other debts.
Should I borrow the maximum mortgage a bank may offer?
No. The maximum regulatory amount is a ceiling. Borrowing less can leave more room for savings, repairs, rate changes and other life costs.
Does a bigger deposit increase how much house I can afford?
It can reduce the mortgage you need and may improve your LTV position, but your income and monthly affordability still matter.
Can I borrow more than 4 times my income in Ireland?
Lenders have limited allowances above the standard LTI limits. Whether you receive one is entirely dependent on the lender and your circumstances.
