Yes, I am one of them. I agree, there are no real estate bubbles in NYC, San Francisco, LA, Vancouver or Toronto.
I have been waiting to buy a house on the Peninsula in the Bay Area since I first moved there in 1998. Which was clearly a bubble when it came to real estate. And despite being very familiar with the real estate market there and closely monitoring it now for 20 years! it's still "clearly a bubble" and has never gone down, only leveled out it's rate of increase for short periods of time. So yes, the real estate market there is absurd and clearly unsustainable....except that it's sustainable for an appreciable enough portion of the human lifespan that it's functionally the same and being sustainable for my purposes. Remember, "Markets can remain irrational longer than you can remain solvent."
