The heat is turning up on the way homebuyers and homesellers pay commissions to their agents. Stiff competition from discount brokerages, the recent lawsuit and settlement between the U.S. Department of Justice and NAR around commissions and the other pending large class-action antitrust lawsuits related to commission are not only contributing to a downward trend in commission rates consumers pay agents, but could shake up the long-standing tradition of sellers (and their agent) setting and paying buyer’s agent commission.
