Problem with the housing is simple. Housing does not have any value, it's cosmetic item essentially. If different plots provided some sort of amazing benefits people would jump on it. However, most Free Companies do not even trust their leader and will not fork out the money. If you get kicked from the FC than you're out of cash. It maybe called FC housing but it's still tied to the leader and he decides on what happens with it.
Anyways, sorry dev team but housing is worth 0 money because it provides 0 benefits. You need to realize that people will pursue items that benefit them and housing has just no value.
