I will try to do a better job of documenting that one.

In my town, Utility companies get a big deposit on users with bad credit history or with no history at all.

You need to interview and check history on these people.

Know this, even though a tenant comes from another agent, you or your property manager should absolutely do the background checks, credit screening and rental history checking.

You just need a reference to a county where they have done business, then check their recorded documents to verify that their talk has some substance. 

Who drafted the documents that were sent?  

I'm presuming the purchaser would still have to pay for DF compliance documentation?

Since I have no saving or a sufficient credit history I figured wholesaling would be my preferred option.

Ask for references to municipal documentation.

If they had been your tenant for many years with good payment record, you might consider "giving them some slack" for now; if relatively new, you have no history with them to justify cutting them a break.
