The answer is no you do not have to have a Realtor to purchase a home, but it really is a good idea to have a professional looking out for your best interests. Realtors are trained professionals that can help you through the process and save you money. How many homes does one person buy in a lifetime? How many homes sales does a Realtor deal with in just one year? Are you aware that using a Buyer's Agent does not normally cost you anything because the Selling Agent will share the commission with the Agent that brings their Seller a ready, willing and able Buyer? A Realtor can even help you buy that FSBO you saw. This is wonderful because you can take advantage of the knowledge a Realtor brings to the table to help you find what you want and negotiate on your behalf to get you the best deal possible!
