I currently live in NW Houston, and while I'll agree that some places could be Mustachian, it REALLY depends on the specific area and your personality. Personally, I have about a 6 mile drive to work (15 minutes), girlfriend has about 10 miles (20-30 minutes). This is coming from Austin where I biked 1/2 mile to work (but my girlfriend still drove ~15 miles then).
There are a few apartments within a couple of miles of my workplace, but they're not ones I'd want to live in, and are about the same price as my current place, not to mention farther from my GF's job. Biking in my area would be risky at best, I've seen people on bikes on the roadways around here maybe twice in the last year and a half I've lived here. No bike lanes, small shoulders, nonexistent sidewalks. It's not at all designed for biking. Almost everyone here commutes 45++ minutes one way every day (8/10 people I asked at my office commute 50-75 minutes one way), so they get pretty pissed off if a person on a bike slows them down. Not something I'm interested in trying to reform myself. Add to that the crazy heat/humidity in the summer and the car exhaust, and biking is not something I'm interested in doing for transport to work in this area. COULD I bike to work? Yeah, if that was my main priority. For me it's not worth it. If I bought a house I could get a nice one closer to work and bike, but right now I'm not interested in doing that. Even then, my girlfriend would still have to drive to her job. Public transportation here is very limited. I'm sure there are some people/locations it's perfect for, but they are definitely the minority.
Cost of living here is relatively low, so I'm told. I've only lived in small town TX, here, and Austin. There is a park and grocery store within walking distance of our apartment, which is nice. The main driving issue is meeting up with people. The average person commutes so far every day, it's going to be hard to convince anyone you get together with that it should be close to your house, so you'll probably have to drive at least a fair bit to get to meet ups. For example, if you live within a half mile of work, make a work friend, and want to go do something with them, there's a decent chance they live 40 miles away. They probably also don't want to go somewhere super close to work, and have some bar or restaurant they really like 20 miles away. Whether that is an issue for you is for you to decide. I frequently have family or friends who are "in Houston visiting" and want to get together, but finding somewhere halfway between us can result in a 45+ minute drive after work during rush hour just to get dinner. It's pretty tough to tell someone you don't want to drive 30 minutes (what google maps says) to see them when they just came in from somewhere 4 hours away and want to see you.
Restaurants here are great, but again very spread out. We don't eat out very much, but do occasionally when people visit. There's a stellar Pho place about 2 miles from us, but again I wouldn't be comfortable biking there. One problem is someone always knows of this "great ____ place" that they want you to go to with them, and it ends up being 25 miles away. We go rarely and have people come over to our place for dinner often, but it's still tough to constantly turn people down, especially when they may be driving farther than us.
To sum up, I'd recommend coming here and checking out the specific area if at all possible before deciding. At least figure out where it is and let us know so we can get a better idea for you. If you can spend a long weekend, and preferably a few weekdays in the area to see what it's like. The culture here is so casual about driving long distances, socializing is difficult without long car trips. If you work a typical 9-5, even worse.
