I provide listing services in the DC metro area. I charge a fee of 4.5% for any sales price over $100,000. The going rate nationally is 5.2%. Most realtors will discount if asked but I believe in treating my sellers equally. Home listing is great for a realtor. There’s no better advertisement for buyers than having a home listing. Open houses rarely sell a home except in an extreme seller’s market like a few years ago, but they can definitely bring in buyers for other properties.
