Be competitive and try to offer between 2.5-3%. This will help prevent 90% of buyers working with an agent from being steered away (yes, it’s illegal and unethical, but it absolutely happens).
Think of it as a necessary cost for being able to access a buyer directly. About 5% of our sellers sell directly, without any agent involvement. You could set the commission very low, which would likely cause agents to avoid you, but that’s counterproductive to your goal of selling the home.
Everyone needs to pay the appropriate price for what agents bring to the table, as they may have been working with buyers for months before “finding” your home. It will also add value to the contract preparation and contract-to-closing tasks that need to be completed.
