With the FC option, I'd probably also check what their policy is for booting people.

In the FC I run, if somebody let's us know theyre on hiatus or we have reason to believe they will be coming back after a little while for whatever reason (like we know of a situation that's taking their attention) then we don't boot them. Though in our particular case, we expect people to be active members when they are here, so we try to avoid having people just park. But every FC is different, so if you were to do this instead of apartments, always worth checking in how they approach this.
