I don't think many home owners got a price for their land that allowed them to buy a similar house elsewhere.

The world is far from an ideal model where what you get is what you deserve.

Note the history of the East Side power plant, which depressed property prices. Ditto, I-35 construction plans. The article says the plant will become a park now. After the new developers locked in purchases.
