There is one thing to be careful of here, and that is the use of the word "standard". There is no standard, or there isn't supposed to be. All commissions are negotiable, always. The last agent was right on when she mentioned the multiple listing services. If you are a buyer and the property is listed, you don't really have a say in what the buyer or listing agents are going to get paid. If you are working with an agent and you are wanting to make an offer on an unlisted property or a â€œFor Sale By Ownerâ€ you will need to negotiate with your agent as to what they get paid. If this is done in writing then this is a buyer's agent contract. The buyerâ€™s agent will try to work it out that the seller pays the commission. What might be happening here is that two agents are trying to get paid for the work of one agent, i.e. one agent had an unlisted property in his or her pocket and told another agent and the agent had you as a buyer. The seller may not have agreed to pay a commission, so they put it on your side of the balance sheet. I can only speculate because I don't know all the circumstances. If I knew all the details, I could probably be of more assistance to your exact situation. Feel free to email me with more detail. I am intrigued. Do you have a buyerâ€™s agent? If not you should have one to look after you and be able to answer these questions for you..... The real question is; Do you feel you are getting a "good deal" that you can be happy with, regardless of the commissions etc.? And, Do you want to continue with the sale?
