She is looking at national details. Real-estate prices are very much localized in my experience. I can have a property that is plummeting in value, while a neighborhood just on the other side of the main road is nicely increasing in value.
To me if I sell for no profit at the time the house is sold, I won. If I pay rent X every month, I will never get that rent back. If I pay the same X amount on a mortgage, even if I get half of it back, that is a gain of 50% over rent.
