卖apt找房地产代理有什么坑要注意的吗

随便在zillow上找了一个当地的代理 排在网页最上面 评价不错 团队很大 给我回复是： I would price this at tbd need to see the place Comish is 4.9%- 2.4% to my office, 2.5% to buyers broker 3.9%- if its my own personal buyer, not anyone in my group, just my buyer (dual agency) 2.4% no buyers agent No start up/back end/hidden fees Cancel anytime for free
请问代理费可以谈吗？大家都是按他说的给吗？ 谢谢
