Manowar:
Check above! :-)
All places are really dependant on what folks want... "paradise" is not necessarily of relevance if someone likes the middle of Manhatten etc.
Another country which still has connotations that, for some reason, puts people off is Nicaragua. The truth is Nicaragua is not some war zone :-)
Today, Nicaragua has excellent comms, decent roads (better than Costa Rica) and banking facilities are no problem.
The main factor about Nico is land values - tho these are being grabbed up now - there are still loads of deals on properties with character and all the original fittings blah.
The cost of living in Nico is about 30% that of Costa Rica and they welcome folks from abroad. Tax? They are something to hold the carpet down.
