There are conflicting numbers on how many homeowners are selling their homes themselves, and some of the information reported is interesting. The National Association of Realtors, or NAR (not exactly an unbiased source), reported in a 2006 study that 13 percent of sellers conducted a transaction without the assistance of a real estate professional in 2005. According to REAL Trends, in 2006, 20 percent of sellers sold their homes themselves.
