Agent Commissions too high?

[Jeff Moore]

Selling my SFR, real estate agent put a total of 10% of the purchase price on the fee estimate. 6% for him and 4% for the buyer’s agent. This seems excessive to me. Is it? Every google search yields “average of 6%” split between seller agent and buyer agent. He’s done a great job but I think we’re, AT LEAST, 3-4% too high here. What do you think, real estate agents of Biggerpockets?
