Negotiating the sale. In Texas, buyers who have signed a Buyer Representative Agreement with a real estate agent, are represented by that agent. That agreement obligates the agent to work and negotiate in the buyer's best interest. When a seller has a signed listing agreement with a real estate agent, that particular agent works and negotiates in the seller's best interest. So if a buyer does not have an agent, the buyer is left to negotiate against the seller's agent, who is highly trained in negotiating skills. Typically, when a buyer is represented by an agent by way of a signed Buyer Representative Agreement, there is no fee to the buyer, unless stipulated differently in the agreement. I do not charge a fee to the buyers that I represent.
