Sure, Natalie, if all you want is to be on the MLS. This is what is called a limited representation listing and basically means that you get no representation whatsoever. Furthermore, you will still be paying the buyer's agent (most ofter) and therefore will have a pro representing the other side.
I love this:
A man sees a doctor and is told, "Your appendix has ruptured. I will need to remove it immediately and it will cost $4,000."
The man replies, "Will you take $1,700?"
My point is that if you are comfortable enough with the details of a transaction that you feel you can hold your own against someone that does this day in and day out then this may work for you. Please understand that when I say that there are many non-agents who have enough experience to pull this off. In that case a limited representation listing may be appropriate. But remember, when you are represented your overall liability is significantly reduced and the headaches are minimized.
Best of luck with your sale,
