For Sale By Owner is not a bad thing, however it does entail some extra work on your part, that a Realtor can help you with should you decide to list with a Realtor instead of By Owner. For starters be prepared to take a number of calls if you sell By Owner. You will have serious buyers calling but also some curious people or potential sellers in your building calling to see what price you are selling your property for, amenities and other questions they might have. Usually a Realtors office or the Agent will handle these calls for you. You will need to market your property properly, you can start by listing it with a Buy Owner website, place flyers in the local coffee shop and let your friends know. Keep in mind that a Realtor has the tool of the MLS which should you decide to go with a Realtor your property will be listed on.
Please keep one important thing in mind when selling By Owner, SAFETY! Realtors when showing a home are dealing with qualified clients who they may have been working with for some time. As a By Owner you are inviting strangers int your house that you really do not know who they have been qualified and how serious they are.
