A few questions for returned player

[Mikasa_Ackerman]

Hi all, I have been away for 2 years and now I'm trying to re-learn my roles now.

1) I recently bought a room in a FC estate and furnish it with bed and stuff. But I do not have the option of "Log out" or "Exit" like the one in the inn when I click on my room's bed. I was wondering if it gives the same rested experience as the inn if I just log out in my room?

2) What is maximum number of retainers you can have? I heard the expansion gives more retainer? I bought the expansion but can't seems to find the clues on getting additional retainers except from mogstation.

3) I read SE are freeing up more estates from inactives. How do I know which one is avaliable? The icons are really confusing sometimes.

Cheers
