This is one of those questions I get from overseas applicants a lot – what is the average rent in Ireland. Of course it differs for a number of reasons (location, if you want to share etc). Thankfully, Daft do periodic reports on this. According to them, average rent is now €765/month.
A 1 bed letting in Dublin varies from €620 to €991, with an average of €797/month.
