"This index takes the speculation and surmise out of renting," commented Ann Marie Caulfield, the Director of the PRTB.
"All our data is based on actual rents being paid for private accommodation right across the country, and this is very valuable information for all stakeholders concerned," she added

Unlike other rent reports the index is based on actual rents paid for rental properties as opposed to asking rents.
The report was compiled by the ESRI and the data is based on the PRTB's register of tenancies.
The report shows that compared to Q1 2012 there has been a 2% increase in rents in Q1 2013, a 2.3% increase in Dublin rents and a 0.8% increase in rents outside Dublin.
Rents in Dublin fell in the first quarter of 2013 by 1.9 % when compared with the final quarter of 2012
This was due to a weakening of apartment rents in Dublin, which declined by 3.9%.
Outside Dublin rents grew by 1.7%, having fallen in the fourth quarter of 2012.
It is intended to publish the report on a quarterly basis. (Source Irish Landlord and RTÉ News )
