The average cost for a realtor to sell a house in the current market is around 5-6% of the sale price. This commission is typically split between the listing agent and the buyer's agent, with the seller paying the majority of the fee. According to recent data, the average cost for a realtor to sell a house is around $15,000 for a $250,000 home sale. However, this cost can vary depending on the location, type of property, and the specific real estate agent or brokerage used. Additionally, there may be other costs associated with selling a house, such as marketing expenses, closing costs, and title insurance fees. It's important to note that while the cost of using a realtor can seem high, they can also provide valuable services and expertise to help sellers navigate the home selling process and potentially sell their home for a higher price.
