The joy as a consumer is there is no set commission rate anywhere in America. It’s a private negotiation between the seller and the agent. Your best bet is going to be to interview as many REALTORS as you’d like, then see whose service and price meet your expectations and budget.
If you’re looking in Hendersonville, I’d suggest Kathy Hannah (Century 21), Cheryl Bretz (Keller Williams) and Cindy Sample (Coldwell Banker Lakeside). They are all amazing agents who will be honest and knowledgeable. Let me know if you need me to connect you with them.
