Your Time. Acting as your own Realtor takes time. You will need to arrange showings, learn how to use the contracts and disclosures, deal with a low ball offers, take phone calls from buyers and Realtors who will be asking questions, and spend time on marketing. Is this the best use of your time? One of the biggest lessons I have learned in life, is that you should focus your time and energy on what you know, are good at, and what you enjoy.
