Somewhere in this chain are parties who are able to claim assets or collateral with values far in excess of actual market worth. To me that smells like the creditors are defrauding their counterparties.

The defrauded parties might include secondary lenders (to the property mortgage holders), regulators to whom financial instruments and solvency are being misrepresented, tenants who are paying higher-than-market rents, potential tenants who are denied market-rate rents on existing space, and arguably communities in which business and commercial opportunities are depressed due to the denial of access to real estate at market terms.

The operator of the building isn't the key point to fraud, as their interest (reducing rent to attract tenants) is actively thwarted by their creditors. The element of fraud is misrepresentation of true market value / income potential by projecting partial tenancy at elevated rates as if it were full tenancy, rather than the actual income stream at full occupancy (allowing for a nominal vacancy rate) at actually-supportable lease rates.
