Tenant screening a corporation or business

[Bradley Hager]

My question is what is the proper way to screen/credit check a business who will be paying for a residential lease?  

I have a potential renter for a single family property where the company they work for will be paying for their rent.  In West Texas, this is very common because many of the workforce travel from Houston or Dallas on a regular basis and renting a house is cheaper than staying in hotel rooms.  We have this same situation in another rental, however, we had a service do all the screening and listing of the property and they did the background checks.  We are attempting to do it ourselves this time.

I've been told to verify credit by contacting at least 3 of their creditors and seeing their payment history.  Also if they have lines of credit with a bank, get info on how much and their payment history.  Is there anything else to check?  Are there any specific forms/applications for them to fill out to take to their creditors so they provide the information freely?  Am I able to credit check/background check each tenant that will be living there even if they are not the ones paying the lease?

In the end, how do I do this the right way?
