I seem to recall during the crazy bubble period, people were giving offers without contingencies to buy a house.
If you had contigencies, it was tossed out since the seller didn’t want to deal with you.
It’s probably not as crazy now, but I can see the bay area being very bubbly with near all time high stock valuations for a lot of tech shops (apple, facebook, google, saleforce…) and so much wealth.
