I wouldn't expect a significant difference, except that you won't have housing bills while you don't have a house.
Mightn't they have housing fees/parlor fees of some sort if the chapter is looking at building a house in the future? Or for storage/suite expenses? I thought pretty much all groups had some sort of housing/parlor fee these days even if there isn't a snowball's chance in hell of them getting a regular old stand-alone house-corp'ed house.
