In addition to the sibling comment, you can also find relatively cheap housing in some of the Sunbelt although I understand that the real housing crash in Las Vegas has largely recovered.

If you're serious about it, you really need to think about your non-negotiables, your strong preferences, and how high you're willing to go for "cheap" housing. For some people the answer might be a condo in a smaller city that isn't in demand. For others, it might be a house that's out in the sticks someplace. There's also a huge difference between cheap as in $100K and cheap as in $300K.

Contra another post, you probably don't want land that isn't already engineered. Of course, also consider Internet. I know tech people who manage with satellite but there are a lot of compromises.

I'm a big fan of western/piedmont of NC for remote workers. It's not the absolute cheapest compared to the midwest, but the weather is better if you don't love snow, and it's still extremely cheap if you're in some non-hip parts (Greensboro, High Point, Winston Salem are very affordable small cities that have universities, and other less-connected mountain towns like Morganton/Wilkesboro/Marion/Hickory are even cheaper, but less vibrant), and there are plenty of roads connecting you to airports and bigger cities with more robust economies (Atlanta, Nashville, Charlotte). Asheville is probably the nicest remote work city in NC, and would definitely beat Dayton culturally, but it's nowhere near as cheap.
