There has been a 2% increase in average national rents in the first quarter of this year, according to a new report from the Private Residential Tenancies Board.
However, in Dublin rents fell in the first quarter of 2013, down by 1.9%, when compared with the final quarter of 2012.
This is due to a weakening of Dublin apartment rents, which declined by 3.9%.
Outside Dublin, rents grew by 1.7%, having fallen in the fourth quarter of 2012.
The PRTB has also launched a new online database of rents which will allow people check rent levels for different locations and different dwelling types.
