True, the model is low and slow. I believe rehabs of degrading row houses are more common in the urban chapters than scratch built: they buy, fix up, and sell to homeowners, involving them and community as my comment above. But yeah, the model doesn't work well for dense housing like condos so they aim elsewhere. If you want to house huge numbers of people quickly, this is not the way to go maybe.
