The concern is perhaps less one’s ability to “market” a house better than a realtor than it is whether the realtor’s services, both individually and as a combined effort between buyer and seller agents, is worth anything remotely like the fees charged. The answer is clearly no to the latter.

With prices where they are today and the combination of effort and skill demonstrated by the realtors I have worked with—each of whom was highly regarded—I would give them perhaps a 1% commission split between them. In all but the most unusual cases, even that would be an overpayment at a reasonable hourly rate for their education and skill level.
