How does that work if I want something cheaper than a single family home such as a condo? I can't build a stand alone condo (I mean a stand alone 600 square foot house on a 0.05 acre lot would be awesome for me but zoning regulations prohibit that in practically all areas of the US). I'd need to organize dozens of people that also want a condo. That's not really feasible for me. I'd also say zoning generally prohibits this in most desirable areas. Developers have the ability to do a lot of legal work to get approvals and permits. Since they are getting approval for a large number of buildings or units, they can distribute that cost and so they can sometimes build in those desirable areas where it would be too costly for me to build as an individual.
