Well, since i have to go against the majority opinion in Life 1 so:
Did this girl tell her that she will like to have a separate house after marriage? If not then she has no right to ask for it.
Is the husband filthy rich? Can he scure a new house that easily? it takes people a lifetime to get a house these days. Does he have enough time to manage his own family life and take care of parents from two different houses?
Some one should knock some sense into this girl.
No response from girls?
