Almost half of all mortgages are going to first-time buyers.
The new BPFI Mortgage Approvals Report for August shows they make up 47.3% of total volume of mortgage approvals.
Overall, the number of mortgages approved has risen by 5.7% year-on-year.
Banking and Payments Federation Ireland Director of Public Affairs, Felix O'Regan, said first-time buyers continue to dominate the market.
Mr O'Regan said: "Well it's good to see the single-largest segment in the market remains first-time buyers. So whether you look at by volume or by value, almost half of all mortgages approved are going to first-time buyers.
"So they still remain, by far, the single most important part of the market."
