Sellers are having to wait an average of 9 months to shift their home, as buyers hold out for better deals.
According to the latest survey by property website, Daft.ie, some properties aren't shifting at all.
Of the 3,000 properties for sale at the start of 2010, some 1,000 have still not sold as housebuyers either hold out in the hope of a further price or because of the lack of mortgages being approved by the beleaguered banks.
The average asking price is now €210,000 - down 43% since the peak of the property boom around four years ago.
Ronan Lyons, economist with Daft.ie, signalled little change in the market with prices continuing to be pushed down.
"Prospective buyers find it difficult to get the finance, while owner-occupiers are often restricted by negative equity," he said.
"As a result, the market is moving very slowly.
"Of the 3,000 properties posted for sale 15 months ago at the start of 2010, one in three is still for sale, although in Dublin the figure is closer to just one in six."
Asking prices have fallen by 4.1% in Dublin since the start of the year and almost 5% in Galway.
In Cork and Waterford, prices have dropped by about 3%.
Limerick has seen falls of just 2%, while outside the main cities, asking prices are down by an average of 2.7%, the smallest fall in three years.
