Your revenue in commercial real estate is imaginary. If your building is vacant 100% of the time for the year, your revenue is 12 months x your desired rent.
Then you have an expense of 12 months vacancy.
You can get loans based on your revenue.
Additionally, it's the reason you see concessions of 1-2 months free all the time - but landlords will never reduce the rent.
concessions are expenses. Revenue is 100% of their desired rent.
Perhaps instead of a covenant it could be more implicitly enforced by suggesting if there is a revenue drop they’ll revalue the property and force the landlord to make up the difference which could be financially ruinous for some.
Can't they extend the trick, so that they have one unit that rents at $100B that always has the vacancy expense of $100B? Then they can set the other rents as they like with little impact to their revenue
The commercial landlord financial infrastructure is broken, but gameable.
Also, a land value tax would fix this (and many other real estate market distortions)
