I saw this in the live letter

Q2: Is the timing for purchasing plots in Shirogane the same for free companies and individual players?

A2: We are currently in the middle of investigating how much of the player population owns housing, so this is still being decided.
I really think it should be open to FCs and individual. I know there are a lot of people who make an FC with just them self to buy a house anyway. Shouldn't really have to wait if I decide I want to move to the new area as an individual. It would just seem easier if both open at the same time.
