Buying inside of Boulder is a bit insane right now, hell most of Colorado is, and it's just amplified by the lack of supply in Boulder (no new building for 20-30 some years I think).

Check out Gunbarrel, it's about 7 minutes away from Boulder and is still somewhat reasonable. Although my SO bought her 30yr old condo for $165K in the Fall of 2014 and Zillow is now saying 302K, LOL.
