I feel like this wouldn't be hard for SE to do. 4 people sharing a small house is fine, but maximum of 4 in a mansion is an awful lot of space for very few players. Can we at least share with 6 or 8? Tenant numbers that scale with house size would be reasonable.

Please don't make this into a "that's what fc housing is for" thread, there's a difference between sharing with 6 vs 100. It's not a solution to the housing problem in general, but I feel it's a step in the right direction.
