My point was that "better than OK with $400k" will get you a mansion in Dallas' northern suburbs or a very nice rambler with a pool inside Dallas itself, not a condo with an $800/mo maintenance fee. I'm not bagging on condos, either, but not everyone wants to live in one, plus the better ones in Seattle are getting picky about who can buy. It floored me to see an ad for a condo saying "no dogs." (Who bans dogs in Seattle? That has to be a recipe for disaster.)
You're 100% right that you can find cheaper housing in Auburn, Federal Way (mind the gunshots), Everett, or even Spokane. The problem is that living in none of those places gets you the walkable, diverse lifestyle of being in Seattle.
Also, thanks for painting all Texas schools with such a broad brush. I graduated from a north Texas (public, non-charter) high school that is well-ranked, in addition to graduating from a state college for my CSCI degree. My siblings came after me through the same school, one as recently as 5 years ago, and none of us are drooling founts of stupidity who can barely sign our own names. It's almost as though different areas have different levels of achievement in their schools.
