A realtor assists a client in the purchase, sale, or rental of property, such as commercial buildings, homes, or land. As a realtor, you have a number of duties and responsibilities. Most realtors work on commission, so your primary concern is to attract new clients who want to sell, rent, or buy property and are willing to pay for your assistance in doing so. You perform market research and analysis to determine competitive prices for each listing. You also take your clients to visit properties and assess how their needs can be met within their budget. Realtors also negotiate sales on behalf of their clients and draw up the legal paperwork needed to complete sales.
