HomeLight says the top 5% of buyer's agents save clients 2.5% more. Should I believe that?

A marketing statistic like that should be treated with some skepticism until its methodology is understood, since Joel Boss has not independently verified how that specific figure was calculated or whether it applies broadly. What matters more in practice is whether a specific agent can point to actual recent negotiated outcomes on comparable properties, which is a concrete measure rather than an aggregated ranking claim. Asking any agent, including Joel Boss, for real examples is a more reliable way to judge their negotiating value.
