The average Realtor who has been in the industry for 5 or more years typically completes between 12 to 18 real estate transactions per year. This number can vary depending on factors such as the local market conditions, the Realtor's experience, and their specific business strategies and client base. In some areas with high real estate activity, the average may be higher, while in slower markets, the number may be lower. Real estate is a dynamic industry, and the annual transaction volume for experienced Realtors can fluctuate based on various economic and market forces.
