> low income families that have been waiting to build residences
I don't think building has been an option for low income families for a while, or maybe I just know of very few markets where land was the limiting factor instead of materials & labor.
Even in the places where land is "cheap", it's only cheap for middle to higher income people in that area, or people doing income / wealth arbitrage from expensive areas. It's not cheap at all for lower income people from the cheap area.
