last I heard Coronado and La Jolla were areas that went against the trend and saw increases during the last Housing bust. I have never researched this to confirm the validity.
It wouldn’t surprise me and here is why. There are a lot of officers on Coronado so they would not have been inpacted by the bust. And in La Jolla SAIC was going gang busters which in the 80′ so ther was a lot of cash flowing through the area.
