Commercial Due Diligence - Professional Thoughts

[Mike Higgins]

I am an agent in Wisconsin and am in the process of trying to gather information for a buyer of mine to buy a 36 unit complex for $1.2mil. The listing agent (in my opinion) is terrible with follow up and doesnt seem to have what we are looking for. She does have the rent rolls and "expenses" (according to the seller), but there is no P&L or CAP information or anything else.

I am very persistent with my questions and follow up and it seems to take a while for her and she is starting to think im a pest!  

What are some common things that you seasoned investors look for when dealing with a property this large?  Am I out of my bounds for asking for all of this stuff?
