According to the information provided, the average number of houses that realtors sell annually can vary significantly. While the National Association of Realtors (NAR) reports that the median gross income of realtors was $56,400 in 2022, the number of homes sold can depend on factors such as the realtor's experience, the local market, and the time invested. The data suggests that the average realtor sells around 12 houses per year, but this number can range from around 300,000 in home sales for an experienced realtor to 1 million in home sales for a high-performing one. Ultimately, the number of homes sold annually by realtors is not a one-size-fits-all statistic and can fluctuate based on various market and individual factors.
