Ideal Agent pre-negotiates the commission at 2% for the seller’s agent, so if a buyer comes without an agent, that’s all you pay—which does happen, especially in a hot market. If a buyer’s agent is involved, they offer 2.5%, so the most you’ll ever pay is 4.5% total.
My parents just went through them and saved a solid amount compared to the traditional 6–6.5% they would have otherwise paid.
