I live in one of the cities on that list. It is definitely a thing. People can move here and pay cash for homes, after selling their homes in an extremely high COL area.
But this city isn’t a red city by any means. It’s just another blue city in a red state. Which a lot of the ones on that list are.
The OpenDyslexic font helped with me. Does a similar thing.
