It wears thin, after a while. "Been there, done that" in my early 20's, for about 18 months... it was more exciting then because I was "young and hopeful" but that was offset by being broke... even then, I realized there are certain comforts of life you just can't have in a suitcase.

I have no experience with Greece, but my parents were expats and property owners in Spain for many years, and it was a pretty smooth lifestyle one the initial paperwork was in place.

I hope the legalese and immigration-ish stuff settles for you sooner, rather than later. With the general state of the Greek economy, one would think they'd fast track anyone who's already committed to investing financially in real estate... all the best to you.
