House prices have fallen by almost 3% over the last three months, with the rate of inflation expected to flatline by the end of the year.
The details are contained in the latest report from property website, MyHome.ie, in conjunction with Davy.
The asking price for houses nationally - during the third quarter is down 2.8% on the previous quarter - to an average of €269,000.
In Dublin meanwhile, the average asking price was down 1.4% in the quarter, to €376,000.
"Everyone knows there's been a big slowdown in Dublin," said Davy Chief Economist, Conall McCoille.
"But it's outside Dublin where you know inflation is running at 4.8% but we think that's coming to an end pretty quickly," he added.
"So why is this? First of all affordability, houses in Dublin and Ireland aren't cheap relative to incomes.
"But, also Brexit itself. We're seeing a very clear message from the surveys, from the estate agents we speak to. That people are holding off on transactions now over the uncertainty."
