After reading this thread, I looked into real estate in Mexico. I may just not know where to look to find the cheap houses since I can't read Spanish, but all I'm finding is stuff over $100K. The apartments on craigslist are also not any cheaper than the one I'm already living in. If that's the reality of real estate there, I could do better in the midwest or south in the US.
I am drawn to the idea of living there just because there would be less pressure to have "stuff." And so many cities, like Oaxaco, would be a lot a easier to get around without using a car than most of the cities in the US.
Having family in the midwest, and a mother that I'll probably need to take care of as she ages, moving to Mexico would probably not be the best financial choice for me. If family wasn't a consideration, it would be very tempting, especially if I could earn US wages online/telecommuting for my income.
