I am a bit more reserved in my opinion. I have seen brisk activity in the investor stock condos in the central area as well as sub 400k stock in places like Mira Mesa and Clairemont. Ditto for 500k stock in PQ and 600k stock in Encinitas and Carlsbad. I have a buyer who has been scorched on 4 listings in that range in Carlsbad and Encinitas in the past 3 weeks. The home on El Rastro went quite quick and he wanted to save 10k on his asking price and thus lost out because of that.
Good odds that the 600-800k stuff will move in places like CV and 4S but above that I am skeptical. Also we really have to see if/when the tech layoffs will begin. If that starts to happen in earnest things may not be so robust.
It seems like the recession/depression effects will hit San Diego employers in the next year but whether that it sooner or later is the real question.
