I live in "fly over territory," otherwise known as Iowa. The particular town we live in is pretty hip -- lots of people in the "creative classes" -- and it is geographically very beautiful. But our 3-4 county region outside of the main hub is poor. If you are lucky to have a "good" job or -- as in our case two -- you're very lucky. (This town is tough for dual career couples.) Housing is expensive relative to incomes, but it is possible to live frugally in many other ways here. There's also not tremendous pressure to keep up with the Joneses. On many levels and in regard to FIRE, living here has been good for us.
But, the ugly truth is that housing is a real problem. The people who do best here are those who bring equity with them when they move to town so they can "buy down" their cost of housing. On the upside, we have close to zero issues with foreclosures (according to a mortgage banker friend), but I also think a remarkably high percentage of people probably own their homes outright or -- like us -- aren't heavily leveraged. These are good things, but there is also competition for housing which bids up house prices. Fantastic if you're a seller, horrible if you're a buyer. Especially horrible if you're working poor.
When we FIRE we are moving from here -- seeking some different services and quality of life things that we can't get here. We're quite confident our house will easily sell. Someone else will bring wealth to town, and the cycle will continue... for better and for worse. We're somewhat conflicted about this, but while we have saved a lot of money here we have also paid property taxes for many years, done most of our shopping locally, and contributed to community projects and boards. So in the final analysis, I don't feel as if we've had a free ride....
