What makes for an outstanding commercial listing broker?

[Tyler Cauble]

As the title and the description say: What has a commercial real estate broker done on one of your listings - either for lease or for sale - that made them stand out in your opinion?

A few follow up questions:

1. What do you expect your commercial listing agent to do and provide for you throughout the process?
2. Where do you see the landlord's responsibilities drop off and the listing agent's pick up? For example - marketing expenses, pro formas, etc.
3. Anything else?
