text: No you do not NEED an agent but it might be in your best interest to have one. You are buying a new home. The development most likely has their own selling agent. If you go in without an agent you are only a customer to them. The other agent is not looking out for your interests but his sellers.  It is up to you on whether you want one or not but I would recommend it if you have never purchased a new home so you have someone looking out for your interests.
