Your future Dimrat presidential nominee.
Thats $625,000 per home. I'm a builder and could build a great tiny home out of a $4,500 shipping container. I suspect I could get it done for $20K or less all-in. Of course the city fights me on the use of containers because they dont understand them and how structurally sound they are (they stack them 6+ tall and ship them across the ocean, I think they can handle being installed on a gravel sure without an expensive foundation)
Here's one I use for a gym:
Its called a high cube refers to its (height which is the tallest available), open side. Its engineered to be structurally sound with both doors fully open which means I could pop a wood framed wall inside with doors and windows and then close the thing up when not in use to achieve a high degree of security.
