There is plenty of houses... there is 1000s of houses on all servers that is bought and not being used... look at the empty wards... suggesting some rafle or whatever is not the solution, suggest an auto demolition time moved down to 15 days, that way you gotta stay subscribed to keep a house, and if you unsubscribe for a while, it will go instantly in auto demo mode.

Then you got your houses, also put upkeep on houses, so you actually have to work for it, and more on FC houses, meaning x6 times harder to keep as you need if I recall correct 6 people to start an FC, that way you can nullify more 1 person FC's and multiple 1 person FCs on same account/server.
