Earlier quoted context omitted.
You're not wrong. Greece experienced a property bubble that is bursting painfully slowly. Homeownership is high in greece; it's part of the culture and successive governments protected it despite its heavy cost as a populist measure (e.g. by instituting laws that disallowed foreclosures). The bubble has not yet burst completely, that's why rent prices are very cheap.
Is it worth moving to Greece at this point if you have sufficient (ways of generating) capital to sustain your lifestyle? Or would that be a fools errand given the state of the economy?
The problem though is that there is always a danger of a Venezuela style collapse but you can always move out.
