A property might let quicker in the town itself but at the moment they move a bit slowly in the outlying area where i live. That might well change once the bypass opens (rumour has it, the Gorey part will be done by July).
That said, everyone I know who has a rental property here is selling up, including the one I'm currently in.
As everyone above has said, if you gave more info we'd be better placed to give opinions.
