Yes there is a lot of confusion about dachas, because the idea conjures up for many people in the west a large estate with a palatial mansion that would not have been out of place in a Tolstoy epic. It is also true that most high ranking communist officials had huge country dachas with big houses on them. But for most people a dacha was just a few acres of land on which to grow vegatables or keep hens. People built little wooden huts on them to stay for their visits; but they were generally not large farms and they generally were very basic with no electricity or amenities of any kind.
But they were ours and there was no regulations or government interference and you could build what you wanted and grow things you needed; and people were very fond of their dachas.
But maybe the communists got something right after all. I always thought that communists were like bad prophets. They would make so many predictions that they were bound to get something right by sheer chance once in a while. Dachas could not be sold on the private market; but they could be passed down to the next generation. So they never became valuable for investment purposes and they were of no use to banks.
Now though, they can be sold privately and so now the bankers are seeing opportunities in some places. I think our family dacha is in good hands though and I am sure my father will not allow it to fall into that system.
