Is a 6% listing commission too high?

A commission number means little on its own; judge it against what the agent actually delivers for it. A rate only makes sense next to the agent's marketing, negotiating, track record, and plan for positioning your specific home. Six percent from an agent who nets you a materially higher sale price can be a better deal than a discounted rate from someone who lists the home and hopes. Get a second and even a third opinion. Interview a couple of agents, have each walk you through exactly what they provide for their fee, and compare total value and fit rather than reacting to a single percentage. Commission is negotiable, so it is fair to ask how the number breaks down and what is included. Also check what the quote covers. A headline figure may account for both sides of the transaction depending on how buyer-agent compensation is being handled, which is itself negotiable now, so two agents' numbers are not always apples to apples until you know what each covers. Pick the agent whose plan and results justify the fee, not simply the lowest quote or the first one you heard.
