It's NONE of what's posted above.
It's the location.
The pricks that live in 99% of those houses are not native Colorado pricks. They're pricks from California that were poor, Looney Toons pricks living in some 600 sq. Ft. California shitpile that they bought in the '80's for $100k that the pricks sold ten or fifteen years ago for $1.5M, and moved to Colorado to become instant rich pricks and basically rinse, lather, and repeat.
