Pretty much any area where the population growth is really slow. The township I'm at had a population of about 900 some odd people back in 1992 and now they have about 1200, and the entire county has like 12,000 people total. The trade-off is that if you want to go to Costco, you have to be willing to drive for an hour and a half or more, and you are going to have to make some of the things that you are used to having when you live in a city or a metropolitan area, like electricity or water for sewer, and you're going to have to haul your own trash. Low population rural counties cost way less to live in, even with the extensive amount of driving you're going to have to do and the gas. We bought this land we are on for about $12,000, and it was owner financed and we were able to win the bid for it for $600. Would you rather pay $2,500 bucks a month or $3,000 for a mortgage on a house that you will never truly own, or would you rather just live in a camper with septic and well water and solar and starlink for internet? When the land is cheap, building your own home becomes a lot more accessible especially if you're using greener building methods like earthbag or cob or hay bale.
