@Richard McDonald I'm an agent so I know I'm partial to looking for a great agent. As an unbiased person, I think the location/market makes a huge difference. @Account Closed makes a good point about not giving 6% away but some areas the FSBO sit much longer than others. Looks like Ohio vs. Florida.
I love in a smaller market/city but the big advantage to listing a property anywhere is that the other agents see it! The could potentially have a buyer just waiting for your property but if they don't know that it's For Sale than it's irrelevant. I am not sure of your marketing plan but most FSBO will only do a sign in the yard and Facebook.
Basically, you are paying for marketing/exposure plus the convenience of letting someone else handle the paperwork. If you are in a hot market, I say try FSBO for a week or two, if it doesn't sell then you could always list it.
Good luck and hope it sells fast and for good money!
