I think you underestimate the COL difference because you are settling for inferior housing. Do you at least have a low-end house, such as 2000 square feet on a 0.25 acre lot that is all your own? Around here in the Space Coast area, that goes for $150,000. It can be done with a 5-minute commute.
Software developers get paid better than typical, so they can get fancier housing if they don't have expensive hobbies. See if you can afford the things my coworkers have gotten:
1. a house with canal access to a lake
2. a new McMansion (looked like 3000 to 6000 square feet)
3. 11 acres, building the house as desired (he got sheep and chickens for fun)
4. beach condo
5. a house with a boat dock on a large waterway leading to the ocean
I'm going to guess that at least 4 of those are impossible for you. The cost of 11 acres is particularly entertaining. I went for something a bit more modest, about 3500 square feet on 0.39 acres, but it is just 0.9 mile from work and I'm supporting a family of 14 on a single income.
