I would disagree that it hasnt always been expensive here. Well maybe back in the 70’s but that was before this palce was even on the map to most Americans.
I bought a townhouse in Encinitas in 1997 within 10% of the bottom value in the last cycle when people say prices were reasonable around here. I came from a bigger city on the east coast, lived in a higher income area with better schools than we have here and wages were higher there. I found prices to be about double here for comparable properties.
