If you can sell your property yourself, you should.
The owner selling without professional representation sells to someone they know 5% of the time, to someone they don't know 5% of the time, and lists with a Realtor 86% of the time (NAR survey).
I would make a PDF flyer of my property, email it to all my friends, put is on craigslist.org, forsaleforowner.com, and owners.com.
Interview three Realtors, ask them for an Estimate of Seller's Net Proceeds. Run the numbers. Then if you end up wanting to list you'll already have a REaltor to hire.
