Cheaper flats like 15k are almost certainly a scam, and unless you are paying a high monthly bribe for "maintenance" you may get a letter from the local authority that your papers are not in order and the building has to be demolished or otherwise fix your newfound legal issues with the land/permits. Things like that are very common in rural areas.
In bigger cities there are other scams and other rules to follow. Apparently another scam with fake POAs or corrupt judicial enforcers is picking up pace these days too.
Politics being corrupt means that anytime you want law to protect you, there would be a hand expecting bribe. Also, usually medical care in such places tends to be subpar. Etc etc etc.
It might be a good investment, unless taxation on owned property is/will become bad. Unless you speak well local language, dealing with many things related to ownership will be a pain.
