Once sellers stop paying their commission buyer's agents are pretty much going to disappear. As I buyer I have no need to pay tens of thousands of dollars to someone for the work I'm anyways doing myself on Redfin and Zillow.
Agree for commodity listings. A good buyer’s agent will create the supply you want. Mine did it by getting the property before it hit the MLS. Others will convince someone who wasn’t going list just yet to sell.
