Which of the following is a supporting tab for a commercial model?

• A. Argus outputs
• B. Rent roll
• C. Cash flows
• D. Lease summary

Answer: (A)

In a commercial real estate model, you keep a separate source of external data to feed the main calculations. Argus outputs fit this role because they come from an external, specialized cash-flow tool and provide detailed, lease-level data and financial assumptions that the main model can reference. By storing these results in a dedicated tab, you can update them without reorganizing the core model, and the main projections pull from this trusted source rather than duplicating work.

Rent roll, cash flows, and lease summary are typically part of the core modeling framework themselves—inputs or outputs generated within the model—so they aren’t the external supporting data source. Hence, Argus outputs are the best fit as the supporting tab.
