That is what I am saying. When you submit an offer unrepresented, I think it is already implicitely assumed there is no CBB. Thus you should assume 100% that there is no CBB coming your way so you simply build it into the offer by a lower price or by a credit.
You are absolutely right, commissions or lack thereof are never part of a purchase contract whether it is the initial offer or any counter offers.
Besides the documents I talked about above the only other time commissions are discussed in a contract would be in the formal Buyers Representation Agreement.
Recall, commissions are for representation. Representation is performed by a licensee under the employ of a broker right? Even when you bring a client to a new development, technically you get a referral fee for bringing them in. Yet the contracts signed are all between the buyer and developer and you as the agent don’t sign a single thing, only the broker referral. Now on the HUD for a new home, I don’t know if the referral fee is listed or not.
Anyways, I am agreeing with you in a roundabout way, as a buyer representing yourself, commissions are not part of the equation. Assume you get none, but price your purchase according to that assumption.
