The second generation want new construction so you see them moving further and further out into the new suburbs now days (but want to be close to UC schools if possible)
The Rich from China(etc..) buy Quality locals (need someplace to stuff cash) (but also want to be close to UC schools if possible). Will not hesitate to buy old tear down in good area and build new 700sqf home much to the chagrin of some of the locals LOL.
Close to Beach is not such a big thing but is nice if it happens to be near a UC school as well.
