you go to the St Johns Administration building and click on remove roommates or something to that extent, and it allows you to click on different roommates at a time(if you only want to remove a few you can do that too) . After that they will automatically remove everyone you clicked and thats that. thats if you want to remove the sorority house. if you want to get out of one location like the sorority house all you do it make your sim go to another location instead of the school dont get very far after you noticed your roommates have already rode the bike or something then let your sim go to the school.. because with mine, mah roommates wanted to carpool so it slowed me all the way down.
