I would devote my time to building high quality, durable, and energy efficient 3bd 2ba homes in the rural areas surrounding major metropolitan areas, which I would then sell at material cost. Buying my first home (mobile/manufactured) has been a combination of the best and worst thing I've ever done. The house cost nearly 3 times what my grandparents paid about ~30 years ago in the same neighborhood (on the same stre…
Ive actually did some market research into this. Turnkey container houses, built out on trailers (with enough facade to make it look good, but since its not a permanent dwelling you don't have to pay property tax on it). The big issue that I found is that people aren't actually interested in cheap houses, they just want something that is affordable at a discount but will grow in value, just like their parents did.
If the market says the cheapest house in a market is $250k then that is my budget ceiling for equipment and materials, while all labor is provided by myself and any like-minded individuals in a similarly absurd situation. The 'difference' I would be making is the invisible-to-the-market value created by putting the cost of labor and any expected profits back into making the home a standing testament to human engineering.
There would be no marketing, no sales pitches, no brand or company associated with the construction of these homes. Simply going from place to place doing my best to make an insignificant difference at a societal scale and a silent but substantial difference to the families who eventually occupy those homes both now and in a hundred years.
