While what Miranda says may make sense, I'm interested to know the opinions of Irish people (where market prices after joining the EU have dramatically risen). Have many Irish immigrants actually returned to Ireland after that?
Also, I noticed (on this forum too) there are more and more requests like "Looking for someone to sell my property in Poland, will pay high commission." So the speculators are trying to cash in, but it's not so easy to sell a Polish property for a good price anymore.
Seeing as you asked for an Irish opinion......
Although prices are up & inflation is over 5% already for this year I would still rather be in the EU. It was 35 years ago that we joined and things were much worse then. High unemployment, high taxes, Industrial strikes and of course the violence up north.
Things are alot better now!
