> Could anyone have honestly foreseen the pandemic and its ensuing upheavals?
Absolutely. Previous WHO classification has a "Phase 4: Sustained community-level outbreaks -> Medium to high probability of pandemic" designation, which has a roughly once-a-decade frequency historically. Compared to multi-quarter, multi-year scale of real estate planning, 10 years is not infinite long term. Of course it is so in comparison to quarterly earnings, share prices, average tenure of a fund manager, a CEO and so forth, so it doesn't get priced in or gets bundled with other catastrophes.
This pandemic might not be historically unprecedented, but the scale of the reaction to it (most office workers staying home for several months) certainly is.
Of course, one is free to regret.
Now, it would seem that the best we can do is make the most of the information available to us in the present moment.
