Anyway just for the info i wonder if it is possible to buy one of such houses and farm land?

As far i know, modern Russian legislation allows to buy farm land. In practice, it works not always well, but most likely no one will prevent the population of such houses  :D

So people dont like such houses? For example these houses on picture are damaged to some degree but they could be easly restored. But if they are too damaged it is easy to build new larger and better wooden houses. Russia is full of forests so wooden log houses in rural area are most logical to me. I have build banya with my father so i have some experience ;D. But i am not planing to go to Russia becouse we already have a house in Slovenia.  :D
