You could potentially have luck selling it on your own, it just depends how you are marketing the property and if your market is "hot". If you are looking to save money the best case scenerio a buyer comes directly to you with an acceptable offer price and no agent involved. On the flip side you could be potentially losing money because an agent could potentially bring a higher offer in than you could procure on your own.
The two biggest advantages of using an agent is that they will place the property on the local MLS for all other agents to see and a great agent will protect you from potential liabilities which is priceless. When agents are involved you are typically giving 3% commission to the listing agent and 2% to the buyers agent
Many people do not have " the vision " so creating one can be beneficial. Staging a property isn't necessary cheap and could cost a few grand depending on the size of the property and the amounts of rooms you stage. If the house is fully remodeled and you stage it, it often brings the house to life. Once again it just depends on the market and the desirability of the property, if you can create a little bidding war between buyers it could be a beneficial spot for a seller to be in.
If you list the property low enough it will sell itself. If you want to attempt to further protect yourself from potential liabilities, do less work, and have a shot at getting more potential buyers, I'd recommend an agent.
