As such you can not go to the lender on behalf of the owner without written authorization.

Closing agents, title companies and attorneys are not the authority on anything.

The decision making authority.

Is there a specific form that should be used for termination and authorization to disperse funds (earnest money) or is just a typed up word document signed sufficient?

There was an event btw your offer and this closing which could be argued as relevant.Going back to the seller broker, that potentially could be taken to the authorities.

Only ONE property manager was willing to provide ANY information to me, even with a signed form from each tenant authorizing the release information to us.

Hello @Cameron Amateis,Although I am not from Detroit, I can tell you that two most common complaints in this industry are 1) my manager is non-responsive, and 2) my manager is doing work that they are not authorized to do.

The first day I received the complaint I authorized the repair.

You have to prove that there was a valid contract (many wholesaler's contracts will not bear scrutiny), that the defendent was aware of the contract, that he acted improperly, and that you were damaged.You also have to do this all in a way that doesn't bring down the authorities on your head for brokering without a license.And without specific performance, all you get is your actual damages.  

Then that job would would let you use it's authority to extort money from others to make money for yourself.
