I hope this thread doesn't degenerate into yet another "you really should use an agent to sell" diatribe.
As an investor, sometimes it's easier to sell properties via an agent, and other times it's easier to sell them as FSBOs. In the cases where I opt for FSBO, the commission has absolutely NO influence in my decision making. I've already accounted for the selling-side commission related costs when I purchased the property, so the commissions are a non-issue. The primary reason I'd opt to not use an agent for selling properties is that I didn't find one who was flexible enough to with me. In other words, if I sense that most agents in an area aren't comfortable working on deals with creative financing, then I most likely won't work with them--even for cash-only deals. I'm deeply concerned about the relationship for the long-term. I want to work with someone who's flexible and open-minded.
