When examining property value factors created by leasing, which of the following is not included?

When assessing property value factors that arise from leasing, go-green clauses are typically not included as a direct leasing factor influencing property value. Go-green clauses primarily relate to sustainability and environmental practices within a lease agreement, which, while important, do not directly affect the immediate financial or operational aspects of a lease that directly influence property value.

On the other hand, co-tenancy clauses play a pivotal role in retail properties, where the presence of certain tenants can significantly impact foot traffic and sales, thus influencing property value. Ownership objectives relate to the owner's goals and expectations in a property, including aspects like return on investment and asset appreciation, which are intertwined with how leasing affects property value. The creditworthiness of tenants is crucial as it provides insight into the likelihood of timely rent payments, impacting cash flow and risk assessment, both of which directly relate to property valuation.

In contrast, while eco-friendly initiatives can enhance property desirability and potentially attract certain tenants, they are not typically a foundational element used in calculating leasing factors that determine property value in the same way that co-tenancy clauses, ownership objectives, and tenant creditworthiness are.
