Why is she looking at 4 bedroom homes? If you're going to plunk down a million dollars of other people's money, it damned well better be a house with more than 4 bedrooms and 2.5 bathrooms. I'm not saying 14 bedrooms, but if those kids become teenagers in that house with only 2.5 bathrooms it's going to be World War III.
ETA: I suppose she could stick some of the kids in that massive closet or the media room.
