Commercial real-estate leases are often much longer than residential, so, they won't be as affected as fast.

As a result, there's also a whole bunch of subleasing going on in commercial RE, hence, it may end up being a whole chain of random third-parties taking the loss for the owners of the buildings (e.g., companies that need to move out of their office after outgrowing it, etc). Surprisingly, this might make an even better argument for the come-back of WeWork -- their whole model from the start was to makeover the buildings abandoned by the tenants.

Likewise, it may not affect the sale price at all, because noone would want to tank their own REITs, even if the market itself is stale -- the owners have a vested interest in keeping the bubble afloat.
