Killiney is a coastal south-Dublin suburb with sea views, DART access and low rental turnover. Larger detached homes dominate; genuine long-term rentals are scarce. Rents are premium. Watch for short-term or corporate-let listings mislabelled as long-term, and verify RTB registration.
Since 1 March 2026, a national rent control system applies across Ireland, including Killiney. Rent increases are capped at the lower of 2% per year or the general rate of inflation, and rent may be reviewed once every 12 months.
