You don't have to befriend them or endorse them, but but being friendly and unfearful while acknowledging their control of the area and showing them a small measure of respect can save you some major headaches.

However, acknowledge your own contribution to these issues though too.

Last December in a meeting with landlords, the program director, Nicholas Calace, publicly acknowledged the lower rent valuations.

Thanks Will for the acknowledgement.

Exactly when do I present the Seller with a copy of the Hud 1 and then have then sign this acknowledgment receipt document?

From their Online Terms and Conditions:"If a Winning Bidder cannot be reached within 2 hours of ADC's acknowledgement of Winning Bidder, or Winning Bidder fails to timely execute the purchase documents, ADC or seller may declare Winning Bidder to be in default."

Generally in my state, the tenants provide all pest control after acknowledging receipt of the property that is "bug/rat free" at the time of move-in. 

I use ron legrand contracts and on it it has a place where the seller can sign to acknowledge they have recived ernest money from me for $10 cash check or any amount.

I fully acknowledge we should not have signed this as a blank document, but is this now obligatory?

I knew I couldn't be the only one that just needs a bit more than a general acknowledgement.
