What information should I ask for someone who owns their own company

[Brandon Hall]

Hello Everyone,

I currently have one of my rentals available and I have a gentleman interested in renting it. 

He owns his own company and it sounds like the company is pretty new although he claims to have a large contract with one of the bigger contractors.  Because of this he won't be able to give me a normal record of employment with salary on it. 

He also just divorced his wife and is looking to rent a place in the city (closer to work). So he won't have proper landlord references.. What kind of information should I be asking, so I can ensure I screen him the best I can.
