Have you asked why they don't want to live in? If the house is icky, can it be updated to accommodate trends? Is it the cost? Are the girls just not that into living there? Is it badly located? First I'd find out the problem, second I'd try to fix the problem, and third I'd make sure all new members understand there is a commitment to the physical structure. If having a house on campus isn't optional, then the girls have to live in it. Period. If every girl can't commit to the house itself, then either the house has to go or the girls have to go. But before playing hard ball with the membership I'd take a good hard look at the problem and seek resolution.
