Mr. or and Mrs seller, when yo list with an agent and then list it on Craig's list to see by yourself...You not only open yourself up to a whole list of issues, but if you would sell, you most likely will still owe the commission.
When you have a listing contract with an agent, selling it yourself most likely will NOT release you from the contract where in you will still owe the Commission.
I know of a Sale like that. The seller listed his house for one price and then a lower price on craig's list. The seller sold the house and the agent asked for his commission.
Seller said no. Agent told him to take the contract to his atty. In short the atty said he had no leg to stand on.
If you list with an agent, trust that agent to do a good job. But going behind the agents back only undermines the job the agent can do for you.
One other issue is the seller gave NO disclosures and did no water or septic tests...Problems loom in the future.
