I think this is trading off too much for cost of living vs income. As I said in a sibling thread, our family is on one (software engineer) income in central Austin. We walk to most things, we own a big home and a yard, but I don't optimize for cost of living, I guess. Austin pays well enough, and we live with all the amenities on a single income.
In reply to your comment, we also have a super fast internet connection, unlimited cell phone plans, and go out to eat often. None of these things add up to even close to the difference in salary we get in Austin vs being in the middle of nowhere. I am all for reducing the time you spend working so you can be around family, but if you are working ~40 hours for a low salary and making up for it by cutting corners -- I'd much rather work my 40 in Austin and have it all.
If you're working 15-20 hours in the middle of nowhere and cutting corners, then that's another thing altogether.

You probably don't really need the fastest Internet connection at home, cable/satellite TV, an unlimited cell phone plan, a new(er) car, to eat out more than once a month, to buy local/organic all the time, the newer technology things, or pretty much any monthly subscription services.
Go play outside and run around with your kids. Go to the library (they probably have lots of books, movies, music, and even video games to borrow for free!). Cook all your own food. Fix your own car/bike. Borrow things from friends/neighbors when you need a special tool. You can do it!
