i actually knew a woman from the former eastern block (croatia) she and the majority of adults from that time owned a commie block apartment that was gifted to them pretty much for free by the government. nobody uses them because they were built so far away from the city that it was genuinely not worthwhile and most people would go on to either buy their own property or obviously move abroad (as was her case).  one thing commie blocks are good for: padding the "house owners" stats for propaganda.
