Sure, for safety reason I'd move out fast, before a catastrophe. However, the problem is that these are mostly multi-million dollar condos which obviously now have zero resale value and are basically worthless.
I don't know the financial position of each tenant but losing multiple millions in real estate might just be financially catastrophic. As in, they would then have to live in regular homes or apartments which they might consider Section 8 type housing.
In all seriousness while these people are facing a serious financial loss, they ought not stay. This Titanic is going down - one way or another.
The residences are pricey; a penthouse unit sold for US$13 million in December 2016
