Do you absolutely need a real estate agent when selling your Property? No. Should you have a real estate agent when selling your Property? Depends. If you are confident that you understand the real estate market, know fair value, like to negotiate, willing to show your home to prospective buyers and answer their questions, then maybe not. If these are tasks you do not want to undertake, then hiring a real estate professional should be considered. You are free to negotiate the length of the listing agreement and commission. The choice is yours to make.
