Purely from anecdote, I think many people were in government owned housing and were able the cheaply buy when Communism fell. I'm sure there were various schemes, so not sure how often re-privatization happened below market rates, or even if there was such a thing as the "market" for the period directly after Communism. From stories I've heard in Poland there was somewhat of a mad dash to buy as much property and land as possible.

That's my impression as well in Romania, but I was too young to know what was going on back then and my family immigrated to the US shortly thereafter...
