Texas Expansion: Which city?

[Jason Timmerman]

So it appears that Texas has had a robust real estate market for some time now.  We are looking to set up a virtual wholesaling market in a Texas city.  Obviously Houston is going to be a real estate mecca in a few months, but we're not comfortable attempting to benefit from such profound loss.  So Houston is out. 

We have it narrowed down to Austin, Galveston, Dallas/Ft Worth, and San Antonio.  Some of the suburbs of Dallas are also in play.  What markets in Texas are most ripe for a large scale wholesaling endeavor at this time?
