A seller can post a listing on Zillow/trulia for free and get massive exposure. What is the advantage here? Is this somehow complementary to those marketing efforts?
Ironically, most states have standardized real estate forms, so really it's just Realtors® that are clogging up the works and demanding 6% commissions. (Actually, it's just NAR; most realtor agencies get 3%, for working their half of the sale, and then the actual realtor only gets half of that, or 1.5%. All of the rest goes to the middlemen, because historically buying and selling homes was highly labor intensive.)
