Ronan Lyons, Economist at Trinity College Dublin and author of The Daft.ie report, says an increase in properties available to rent in Dublin has caused price rises in the capital to slow down.
"There have been perhaps 10 or 12,000 new rental homes coming onto the market in Dublin over the last couple of years.
"They're starting to have an effect, but the rest of the country hasn't seen any new rental supply.
"In Dublin, if the additional supply comes on stream, we might see relatively stable rent over the next while. That's a bit of an if, but that's probably the most optimistic we can be in the country.
"Elsewhere, the supply is very tight. The number of homes available to rent is incredibly low.
"It's a little bit better than it was 12 months ago, but they were unprecedented levels."
"And with smaller scale landlords leaving the market, the lack of new supply together with really strong demand means that there's still very strong upward pressure on rent."
