Keep in mind this is an average…the smaller the property the higher the price per sq. ft., as you get larger the price per sq. ft. goes down, all your really doing is pointing out the outliers of an “average”. The reality is however the market price is what some one is willing to pay. I can tell you first hand I rented for a short term (6 months, so it was at a premium) in summer of 2015 in the same area (off college and Frazee) and I was paying $2300/mo. for a 2/1, 1000sq ft. with a single car garage and parking spot. The one caveat is that Oceanside is very spotty, if you go north of O.blvd on college there are great schools and it is a really nice area, while south of O. blvd tends to be worse schools and a lot cheaper.
