Department of Finance officials are preparing a detailed analysis of institutional investor activity in the housing market over the last three years.
The analysis will set out options around possible changes to the 10% stamp duty rate on investors buying more than ten properties.
A change to the ten-property threshold is also set to be examined.
The review is expected to go to the Government party leaders soon.
Last June, Taoiseach Simon Harris asked the then minister for finance Michael McGrath to get his officials to look at this issue again.
In a letter to the minister at the time, Mr Harris wrote that the bulk purchasing of homes that are needed by first-time buyers cannot be tolerated.
The Taoiseach suggested too that the higher rate of stamp duty on the bulk purchasing of homes may not have been entirely successful in its goal.
