It took several years for another mmo, Mabinogi, to implement a housing system. It's sort of it's own little city, and there are around four or five located on the map where players can buy a house in a village-type setting, and pay taxes to a castle, run by various guilds. Not that the details really matter, and the differences between B&S and Mabinogi are vast, but it could be entirely possible. Originally, Mabinogi wasn't intended to have the housing system, but in the end it got two different ones far down the road. My preference for a housing system to be implemented here isn't strong either way; it would be interesting to see, and I'm sure it could be done if there was higher demand for it in KR.
