Residential sales agent with comercial buyer's lead

[Tim Mensch]

i am a new agent who just started picking up clients for residential sales outside of Philadelphia, PA. I recently received a buyer lead for a small commercial property.  My broker says it is small enough to take on with his assistance but i am a little skeptical about taking it on. If it was to sell a commercial property i would definitely pass up on it, but working with a buyer sounds doable.  Does anyone have experience with working with a buyer for commercial property?  What are the major differences aside from knowing the local zoning classes?  I have a meeting this week with the client so i wanted to be prepared, even if it is to turn it down.
