What should be considered alongside the rental fee per car to estimate gross revenue?

To estimate gross revenue effectively, it is essential to consider the number of rounds played per car. This metric directly influences how often each car is used, which correlates with income generated. Higher rounds per car indicate greater utilization, leading to increased revenue from the cars. This relationship underscores the importance of understanding not just the rental fee, but also how frequently that asset is generating income through actual use during rounds.

The other options, while potentially relevant to a broader strategy or operational considerations, do not provide the same direct connection to estimating revenue per car. The type of lease agreement relates more to costs than revenue, the total fleet size impacts capacity rather than revenue directly, and the location of the facility can affect business potential but doesn't quantify utilization per car directly. Understanding the usage frequency gives a clearer picture of projected earnings.
