I find Dual Agency (or transactional agency, or whatever your state calls it when an individual agent handles the transaction for both the buyer and the seller)... a lawsuit waiting to happen.
Dual Agency calls for the agent to be fair, neutral and even-handed to both parties, and that's not what your seller hired you for. They hired you, in part, for your ability to be a bull-dog in representing their interests. They hired you to assist with the negotiations and get them the highest price and the best terms possible. They also expected you to represent them in the negotiation for the inspection, if any credits or repairs are required.
Your buyer hired you, in part, to get the the lowest price and best terms possible, and represent them in the inspection. These two things are mutually incompatible.
And, in my opinion, it's being disingenuous, to suddenly in the middle of the transaction to tell them that I can no longer truly represent you...(even though that's what you hired me for) all I can do now is to represent the transaction... but don't worry... I'll treat you fairly.
"Fairly" is not what you were hired for, and now that you can't really aggressively represent either party, you're being rewarded with both sides of the commission.
Not what either side hired you for, in my opinion.
