Not many viewers to this forum because overseas property investment has dried up from Ireland.-Too many people got their figures burnt, including me who stupidly bought in 2006 in Florida (thus my resentment of you buying A Florida place at a bargain price!).
Greek property is almost unkown by the Irish who are heavily into Algarve, various Spnish coasts -and in recent years Bulgaria and Turkey.( mainly from working class Irish).
As a travel agent with a few shops I got to know where people had property - and was amazed in my Ballyfermot ,Tallaght shops at the no. of Turkey/Bulgaria buyers compared to ,say, my naas or city shops where many people had bought near Port/Sp golf courses.
Greece rarely came up from any social class.
If I was younger and wanted to buy in Greece ( and I do share a "villa" in samos and flat in Athens with my siblings) it would have to be close to a lively centre/airport.
Winters on Greek isands or anywehee in greece can be much colder and dismal than people realise Jan-March is miserable. The local busy town turns inton ghost towns as half the population is in the big cities and the rest go early to bhed and huddle round the TV. thr proeprties ,even new ones , are rarely cosy. Loads of marble which is lovely but bloody freezing for a few months.
Crete would be a climatic exception ,especially the south coast -rarely chilly in Winter. rhodes,too, is better than many. Corfu can be wet and cool for many months - far too damp as well.
Evia - but where? My cousins have a place on the southern tip at Marmara ,beautiful but needs aboat trip to get there from rafina -mind you thats near Athens airport.
Personally I prefer northern Evia (nr Edipsos) but that's a long drive from Athens.
My choice would either be on the mainland within an hours drive of Athens .Only becaue I get stir crazy without places to visit, or one of the nearby islands in the Saronic Gulf - Aegina, Poros or Sptses -all with good hydrofoil connections.
Having said all the above iI'd go for Marbella or Nice. Strange for someone with Grek connections speaking fluent Greek,but ease and cost of connections to other places in west Europe, and lots of places to visit nearby are important.
Less important so for others perhap
