Sadly, the biggest obstacle to housing in most communities is zoning. Most communities have strict zoning laws that force out affordable options.
Financial formulas also work against the creation of affordable housing. The financial formulas prevent banks from giving loans to affordable houses on expensive land.
The technology of building has advanced to a point where it is possible to put more and more people into affordable homes. Unfortunately, the financial and political structures of the world seem to preclude such options.
yes the ppl making the zoning rules and causing the issue are the same ones saying they want to fix the housing problems, go figure :) but mind you there would be some land suitable for low income housing, as we have trailer park communities now etc, so there would be a place for printed homes in the market somewhere and it would be nice to see more options on the lower end of the scale with tiny homes and mobile as well at least in some places they are trying as with other rent-to-own solutions too
