Yes, I was also around in 2006. That seems irrelevant as there is adequate data available regardless of when you were born.
> It’s just not the same market as homes.
No, it is, at least when people have to make hard choices. There is no law that says each family gets a SFH to themselves. Sure, they may want that, but when SFH becomes unobtainable people make those hard choices.
If you have more homes than you have willing and able buyers, you have too many homes. Family formation can be delayed(i.e. live with relatives longer) or families can choose multifamily. I don't recall a mass epidemic of homelessness after 2008 left homes empty, so it seems to me that we have enough places to live, even if those places are not the dwelling of their dreams. I understand there are statistics that say otherwise, and similar statistics were around in 2006 and proved to be wrong, so I have to question the recent statistics.
> That’s not going to repeat.
I didn't say that. We may see a 2008 style financial crash driven by commercial real estate, but I doubt even that will happen. What will likely happen is that the folks who think prices only go up will be surprised as the pool of buyers opts out of the SFH market while attrition slowly lowers prices. This process may even snowball in some markets as people "race for the exits" when they realize home prices are losing support.
