Rental prices in Dublin rose by 7.5% in the three months from April to June, the latest Daft.ie rental report shows today.
Prices outside of Dublin rose by 1% over the same three-month period and Daft.ie says that the average rent is now €825, compared to €792 the same time last year.
Daft.ie said the increase in Dublin rents is due to a 43% fall in the number of available properties to rent, with 2,395 properties available at the start of this month compared to 4,212 at the start of August 2012.
Other cities outside of Dublin city have seen a combined 27% fall in the number of properties available to rent in the last 12 months.
Today's report shows that rental prices have risen in Cork and Galway by 2% and 3% respectively, while they fell by 3% in Waterford and were stable in Limerick.
Ronan Lyons, Daft.ie's economist, said the gap between Dublin rents and much of the rest of the country is a trend seen consistently over the last 12 to 18 months.
