If you go it alone, you aren't necessarily saving 5 percent of the home's sales price by not hirng an agent. Most likely, you're only saving 2.5 percent. When a home is sold, the seller ordinarily pays the 5 percent. The seller's agent then splits the commission with thte buyer's agent. If you want to get traffic to your listing, you need to offer that commission to the buyer's agent to incentivize them to show your home. Additionally, few buyers feel comfortable neqotiating directly with an unrepresented seller. Buyers want guidance from their agent and appreciate their feedback. If you don't offer that buyer's side commissison you risk losing eyeballs and therefore market share. If you lose a large chunk of the market, you risk not getting top dollar.
