Yeah, I have casually looked towards San Antonio and even Waco. The problem with the "look where nobody's looking yet" angle is that you're potentially just kicking the can down the road. In 10 years when "the market catches up" it'll be back to square one. Perhaps you'll have equity by that point, but that'll be the only difference.
There's an implicit assumption there that this problem will continue until it consumes most every small city, which I don't think is true. At a certain point, it will either stop at a larger/more popular city level or will spread itself so thin that the original set of cities becomes affordable again full circle. I suspect the first case as the cumulative growth rate of tech slows, but of course that guess is just as good as yours likely.
