Just wanted to share what I know about Zillow and how they're also making money the old way while trying to change the way things are done.
Zillow only makes a deal with about 2% of people who ask zillow to buy their home (currently). The other 98% of the sellers end up going to Zillow "preferred agents". Those agents try to get the sellers to go the traditional route and list their homes with them.
Once the home sells, Zillow gets 35% of the commission check. By doing this, they're starting to become one of the largest real estate brokerages in the world. They have their brokerage license in every state in the U.S. and are doing similar things for buyers as well with their new "flex" program.
