I mean, in my FC only a few people are actively in that house due to other things to do like end game and leveling. So lets say the active people take a break. Suddenly its a chore to make sure we don't lose our houses.

I mean, I say make it to where if the FC itself isn't active for 35 days, then to forfeit the house. That way you know for sure the FC is dead instead of they just aren't in the house all the time.
