The average price for a three bed semi-detached house in Dublin is €433,000 - down 2.2% on last year.
According to a new REA House Price Index, house prices in Dublin have fallen by more than €1,000 a month over the past three months - €4,500 overall.
However, prices in Dublin are still well above the national average asking price which is just over €236,000.
REA says areas such as South County Dublin have fallen by €6,500 in three months to €419,000, while North County Dublin areas such as Swords, Skerries and Balbriggan have remained the same with prices averaging €322,500.
It also says increased availability of new homes has had a "suppressing effect" on prices in some commuter areas such as Kildare, north Wicklow and Meath.
Cork City showed a slight rise of 0.8% to €320,000, while Waterford City reported a quarterly increase of 2.4%.
Developer Michael O'Flynn from O'Flynn Group says the drop in prices in Dublin is just temporary good news.
"Is it good news? I don't think so.
"I think that the market is quite dysfunctional, and this is just another element that's proving that what's there at the moment in the housing area isn't stable, and isn't going to last".
