I just looked up a lot of old places I was looking to buy back in the early 2000s and things have close to tripled. Much faster appreciation than in SD.
I agree that there is no place to build and unless SF falls into the ocean or a nuke goes off, with cash doing what it’s doing, holding bay area real estate seems not the riskiest assuming you can afford it (no crazy loans) and bought at a good time.
Course, a crash can trigger a pull back now that we are definitely at a peak, but assuming the job market doesn’t go to zero (then everyone all over the US will probably be affected in some way), you’re probably ok with holding and waiting there…at least preferably over any other place in the US…
