Just because the job's "in Austin" doesn't mean your home will have to be. There are lots of communities around Austin proper that will allow you a more "neighborhood feel". And even though now you are looking at Killeen as mileage away, it really *is* just a hop and skip up I-35 or, even better, through the countryside in Williamson County. Check out Georgetown, Salado on your way north.
The area has fabulous restaurants, scenery, and things to do. Lots of advantages. And next fall, you'll be right there for the Houston International Quilt Festival!
I envy you!
