Nope, you don't. However, you might want to interview a couple to see what they can offer you. A good one can guide you through the process, negotiate on your behalf, and smooth the way for you to get to closing. Usually the seller pays the commission and you get someone to represent YOU at no extra cost. Why wouldn't you want one?
