Central Bank of Ireland rules apply limits to the amount that lenders in the Irish market can lend to mortgage applicants. These limits apply to loan-to-income (LTI) ratios and loan-to-value (LTV) ratios for both primary residences and rental properties, and are in addition to lenders' individual credit policies and terms. For example, a lender may have a limit on the percentage of your take-home pay that can be used to pay your mortgage.

A limit of 3,5 times your annual gross income applies to applications for a mortgage on a primary home. This limit also applies to people with negative net worth who apply for a mortgage for a new home, but not those who apply for a loan to purchase a rental home.

Lenders have some discretion when it comes to mortgage applications. For first-time buyers, 20% of the value of mortgages approved by a lender may be above this limit, and for second and subsequent buyers, 10% of the value of those mortgages may be below this limit. above this limit.
