> The real trick is convincing the families in those 6% single-family homes to move. No way; that would be a piece of cake. The only reason it's not happening now is that zoning law forbids it. If that were changed, homeowners would be falling over themselves to sell their land to apartment developers; it would be a giant windfall for them. In fact, you'd have to charge a steep development fee to reduce that windfall to something modest in order to ensure that only 6% volunteer to do it.
