The OP want's to stay in Ireland, why are you talking about the People's Republic?Towns like Midleton or Carrigtuohill in Cork for example would all be within a few minutes train commute to Cork, and houses would cost far less than similar in Dublin.
Coastlines of East & West Cork on your doorstep, Ferry to France from down the road in Ringaskiddy and Cork Airport will get you anywhere else via Amsterdam, Aer Lingus goes every day.
