If you have the know-how to do it, then more power to you! Just be aware that at least 80% of people who list FSBO later decide to list the house with a broker. That is, 1 in 5 successfully sell on their own. These are usually people with experience in buying, selling, local law, valuations, and closing processes, etc., if not an actual real estate background.
I've been a landlord and a real estate investor for several years and would still list with an agent if I were selling anything. For me, it's more about time than anything else, but I also think the greater advertising power and negotiating assistance they offer give you a very good chance of getting that 5-6% commission back in the form of a higher sale price and/or more advantageous contract terms.
That's just my $.02. FTR, I do hold a real estate license, paid for by and used primarily for my own investing partnership. I don't consider myself indoctrinated, nor categorically opposed to FSBO. I'm all for people trying it, as long as their expectations are realistic.
