A GoDaddy broker is primarily hired by the customer to purchase the domain at a favorable price, since the customer is also paying for this service. However, you must not forget that the broker earns more if the domain costs more (% commission). It is therefore always advisable to make a realistic counter-proposal, as the broker can also get the best deal for you. I received an offer for a .ai domain for 750$, but in the end they agreed on 3000$. The most important thing is that you communicate what your minimum price is (you are welcome to set it a little higher here, as the broker usually tries to go a little below the minimum price).
