I find it a problem too, that players purchased a house (any size), get two buddies to start an FC, just to turn their house into an FC for the benefits it offers. This should not be happening. This is another loop hole that needs to be closed.

You want a workshop, and house buffs, then you should join an FC. Not occupy a large mansion with only 3 players, if that, just to take up desirable, good FC housing.

On my server the majority of mansions are bought by private owners and I see them with no activity from month to month, only to occupy it long enough so that they don't get evicted.

The housing situation is a mess, for sure. SE should have seen this coming. They should have had a residential are just for FC housing and not mix it in with privately own properties.
