You should be able to get all of the information you need through the local housing authority.

Public Policy and judicial bias are very real and scary.Distinction between Legal Authority and Practical Authority need to be understood also.

Who is the authority that inspects to determine if the house meets rental regulations for safety? 

Authorizes the eviction of a tenant from the property other than by the judicial eviction process set forth in the Wisconsin Statutes.Essentially this means that you cannot put any language in your rental agreement that states that if the tenant refuses to vacate at the end of a lease or after committing a breach, that the landlord is able to engage in self-help eviction.

My instinct tells me to name the seller as the Corporation on the contract and have the trustee sign as authorized party.

Are you speaking with a person with no lending authority, or are you speaking with the person who can approve the loan personally.  

Buy a rental, find a S8 tenant, sign a lease, submit paper work to the housing authority, wait for inspection, fail inspection, fix issues and schedule next inspection, pass inspection, move tenant in, done.There, I just taught you how to do it :-) 

Every day they should call their case manager, an inspector and a supervisor to advise them how important is that the unit is approved so they can be authorized to move in.

That makes them an agent selling something they have no legal authority to sell.

Due to prolific drug activity at his rentals, the authorities threaten to seize his property if he doesn't take action to stop it.
