How Mortgage Affordability Is Calculated

The Central Bank of Ireland limits mortgage lending to 4 times your gross annual income (the loan-to-income, or LTI, limit). This is the primary constraint on how much you can borrow. Lenders also apply their own stress tests, typically checking you can afford repayments if interest rates rise by 2%.

Key Factors

Worked Example: Couple earning EUR 100,000 combined

Maximum mortgage (4x): EUR 400,000. Deposit at 10%: EUR 44,444.

Maximum property price: EUR 444,444. Monthly repayment at 3.5% over 30 years: approximately EUR 1,796.

Note: This is an estimate only. Actual lending decisions depend on your full financial circumstances. Always get formal mortgage approval before making offers on property.
