Property prices in Colorado (Denver) and L.A. (California)

L.A. is pretty expensive, from what I have seen it is as expensive as London with prices around 400.000 for 1 bed flat in Santa Monica, Denver in Colorado on another hand is quite cheap, you can buy 1 bedroom flat for 120.000 american dollars. It makes me think that Poland is pretty expensive nowadays with prices around 100.000 american dollars for 1 bedroom flat in Szczecin!
