Negotiating Commision with Agent Who Is Broker + Dual Agent

[William Coet]

For SFH transactions, when not using a buyers agent and using the listing agent as dual-agent who also happens to be the broker the agent is getting the full commission of the sale. They would be sharing it with a listing agent if there was one, so I am wondering if they are willing to give a portion of their commission back to the seller. If so, how does this happen (i.e., check at closing, check at some other point in time, etc.)?

You have a contract with the seller to purchase the property. 

If there is no dual agency....you are simply not represented. That was your choice not to hire representation. What the listing agent is making is between them and their client the seller. It is of no concern of yours.
