Desoto (the 130K home bsrsharma mentioned) is a lot different than say Highland Park in Dallas. Would be interesting to look at areas like Highland Park, Irving
The difference between San Diego and many of the major cities in TX, is that there has been quite a bit of business growth in TX – so for instance a lot of the home building done in San Antonio is fueled by a lot of the white collar growth in SA versus the traditional blue collar town that it has been historically. TX also has no state income tax. Other than that, TX is a HUGE state and wildly divergent, so its hard to compare TX as a state, just like its hard to compare SF to SD, or Bakersville to La Jolla. Austin demographics for instance are very different than SA even though they are only 1hr apart.
