To buy property in such places makes only sense if you consider to live there for several years, otherwise better to rent something - if something is going seriously wrong, you can disappear and will not lose anything.
About property there is also the question on which name it might be registered. Not all properties can be registered in foreigner's name.
Be careful with advice coming from local girlfriends... just a warning.
About money in the bank, don't do it. Just keep a small amount for your daily needs in a local bank in local currency and otherwise keep your savings away from such countries.
The cheapest place in Eastern Europe (and elsewhere) does not mean it is for you, the foreigner, a really comfortable place.
So-called 'cheapest places' often have problems, like short supply of goods, criminality, missing regular clean water supply, electric power shortage, visa related problems for long-stay, problems about medical care, unstable government... etc.
Do not focus on 'cheapest country' and to 'advice from girlfriends'.
Maybe create a small data-bank in your computer and compare pro and contra of various countries and cities.
