I've always wondered why solutions like modular, "tiny", or even 3d printed homes haven't taken off more when there is such a lack of affordable housing. I know some of it is stigma, some lack of land or cost of land near more densely populated areas...but it's definitely not a quality issue (excluding 3d print, that's too new).

It would be a way better use of money than renting for many people. But how do we get around the "trailer park" stigma? Maybe that's a pipe dream.
