My parents and I relocated to Texas about 10 years ago and I've enjoyed my time here so far. If you live near the larger cities (Dallas/Fort Worth, Houston, Austin, San Antonio), there's plenty to do. If you're more comfortable with smaller cities/towns, there are several communities along I-35, I-45, and I-10 that are nice and allow you to easily access the big cities. The cost of living here is very low and there's no state income tax
The only downside about Texas (in my mind) is the weather. It takes some time, but you get used to it.
