As a former Houstonian (and Montrose denizen), the one problem here is that there is a very good chance your job will not be in Lower Westheimer or Downtown. Which means you could very well be spending an hour on I-10 headed out to the energy corridor to work for one of the Big Oil companies.

Houston is a great 'secret city' that few know about, but the effects of its lack of public transport (insane traffic on the freeways) can be seen daily.

But you are correct, If I was to move back down there I would immediately try to get a place in the Heights or Montrose.
