That's if there are available builders. It took my mother the better part of a year to get her roof replaced, because there was no one available to do the job. I'd also argue that the place she lives in rural VA is pretty awful in most respects other than having space and she's not all that far from a town.
My hunch is that the housing crisis is simple supply and demand. People want to live in cities because of the better access to entertainment, amenities, and services. There aren’t enough houses to fill that demand. There’s no great city on earth that has a glut of housing. If there were, people would flock to that city to fill the housing. I think that’s the very nature of a city. In some sense, the more people that want to live in a city, the higher the quality of the city. That’s also directly correlated with housing cost, sadly.
If you have the money to outright buy a rural property and build a house there, it's not a bad place to live. But you don't want to have to depend on the limited job market with an expensive mortgage and limited buyer pool.
