Potential tenant setting up his own business and no job history

[Kunal Pathak]

A young potential tenant (college dropout I believe in early 20s) has applied and has excellent credit score and credit check but the credit history is just a year long or so. Trying to setup the business so no W2/Tax documents to show as a proof for income. One month bank account has been shared but that I don't feel comfortable renting to him/her just on the basis of that. They are staying in their current place from past 8 months and their current landlord gave good reference of paying rent on time,  but I don't see a reliable source of income to make my decision.

Any thoughts?
