Is it reasonable to expect her to move out when she can't afford it? I can't think of anything more reasonable. Housing isn't guaranteed. This isn't simplistic.

Is it reasonable to expect her to move out when she can't afford it? I can't think of anything more reasonable. Housing isn't guaranteed. This isn't simplistic. It's how the housing market works. It might not be fair, but that doesn't make it wrong. Plenty of us have had to face a move because of cost. It's not easy, but we don't whine about it, we accept the consequences and we deal with life.
