By comparison to SF and LA its high. If you're not white you'll feel it and every now and then if you like the bar/ club scene when you try to get in the bouncer will say "Your pants are too low" which in my opinion is code for "your skin color is too dark"

Houses sell really quick too. If the current trend continues for another few years in Austin, it will be at Boulder, CO levels for housing (which isn't that far off from Bay Area housing prices).
Now compare Austin to Houston or San Antonio. (Besides, $100/SF is low unless you are talking about the East side.)
You can get quite a large house in Buda for $150K
