Leasing Apt Unit to Company: How to Screen and who signs?

[Chase Banta]

We have a 36 unit complex in Lake Tahoe, and have a verbal agreement with a company to pay above market rents for a year lease on one of our units, but our only experience in screening and signing tenants is with normal people.

We're looking for some advice from someone who has gone down this path with a company before. Basically, we want to know what we should be requesting from them for screening (e.g., bank account and statements, contact with the person who has authority to sign checks, looking for whoever it is that guarantees liabilities for the company), and how the lease might differ from the standard lease the California Association of Realtors uses.
