A large chunk of the midwest is like that. Housing is very cheap in the small-medium cities (and the big cities are still a lot cheaper than the coasts) and you'll usually find a few local software companies + satellite offices of bigger ones that pay in that range.

There are a few different rankings that sort of assess this.

There's a CompTIA "Tech Towns" report[1] from last year that does a good breakdown of salary + job opportunities vs CoL by city.

Anecdotally, I think it was right to rank Charlotte NC at the top. It's easy to find 100k+ salary jobs there if you have experience (avg is a bit lower though) - and median housing prices are like 230k. But the big downside is that you pretty much have to be cool with working for a bank.

Dallas, TX is one - but as resident, I up and moved to Denver because .... ugh.

There are numerous cost of living calculators[0] online, but they basically just tell you how much more or less you need to earn to maintain your standards if you move to another city (not neighborhood level). Still, they're interesting.
