The vast majority of home buyers begin their search on-line. Websites like Zillow and Trulia attract 88% of active buyers. Despite that statistic, some people still attempt to sell without the help of a professional realtor. They pay for a newspaper advertisement. MAYBE someone from the other 12% will see it. They tack a sign to a tree in their yard and hope for the best.
Seriously? Realtors have access to the Multiple Listing Service (MLS), which shares information with over 30 additional websites. Now THAT'S visibility. Which strategy makes more sense to you? I thought so.
