A career in real estate does require a financial commitment. Licensing course fees, Board of Realtors membership dues, continuing education and other business expenses (phone, computer, office supplies, personal marketing, etc.) are just a few of the expenses you need to consider when getting started. On average, the start up costs associated with this range from $1000 to $1500. For the Keller Williams agent fees, they vary from office to office. Expect to see monthly agent fees between $50-$85.
