Rhonda did put it well. Either way though...even if you do "sell" and not "list" your home...I would advise you to hire an attorney who specialize in real estate transactions to assist in the paperwork. You will be thankful you did!
Best of luck!.
There's some level of risk involved selling real property. You just have to decide if you're willing to take that risk.
You got bombarded. the overwhelming answer that as the owner of your home, you have the legal right to sell it without help from anyone. One of the best places to get ideas fot marketing it, or to really check out what an agent could do for you, might be to call 3 local agents and ask them to do a comparitive market analysis of your home, and to present how they would list it. Maybe one would be full service, one a "help-U-Sell" agency, and one, a discount realtor. If you still want to sell it yourself after seeing the plans, you'll have some good estimates for pricing it, and some great marketing ideas.
If you just want to "sell" your house, you can do so by putting a For Sale By Owner sign in your yard and contact a title/escrow company to handle the paperwork.
Of course being an agent I would advise you to hire someone as they can help you through the sea of paperwork, answer all your questions and best of all the agent will pay for all the advertising expenses associated with marketing your home. Good luck!
Being a Realtor, I would, however, recommend that you interview a local Realtor to learn more about the services they provide and the benefits for you. In a buyer's market, simply putting the home in the multiple listing service may not be enough. The Realtor can also advise you on pricing, additional marketing, negotiation, etc.
However, the fact that you're asking the question--and it's good to ask questions--suggests that you at least might consider using a Realtor to sell your home...or at least interviewing some Realtors to see if you'd like to go that route.
But people do sell their homes on their own. There are plenty of books out there on the process. You might begin at http://www.amazon.com.
