Any person can search for commercial real estate space on their own. However, a broker can do much more than just find a space. A broker uses their expertise and market knowledge in the leasing process. Brokers also have access to various search and marketing analysis tools that are not available to the public. A broker starts with a good understanding of your business and gives you advice as to the best space suited for you, based on location, demographics, traffic counts, rental rates, etc.
