From what I've heard (realtor friend), the Russians prefer LA to SF. Sure, there's a "little Russia" in the Richmond district, but there aren't too many Russians interested in the Bay Area (unless they're working for Tech in the area, of course).
Interesting cultural insight about Chinese money preferring SF while Russian money prefers LA.
Is it really true that Chinese money prefers SF? Chinese money definitely loves LA, perhaps its impact is just more pronounced on a smaller city like SF?
My knowledge on this is purely anecdotal, I'd love to see some data.
