Texas definitely has lower housing costs, and no state income tax, which is a big plus. However, salaries are generally adjusted to reflect the lower cost of living, so don't expect to make the same as you would in the Bay Area. While Austin is a tech hub, the sheer concentration of tech companies in the Bay Area still makes it a strong contender for career advancement if you are hyper ambitious. For your wife, marketing jobs are pretty plentiful in both regions. Culturally, Austin leans more liberal than other parts of Texas, but it's still not as progressive as the Bay Area. Think about what truly matters to you both in the long term.
