是8月17号开始实行吧

Big changes take effect this month that will mean seismic shifts in how most Americans buy or sell a home and could ultimately drive down residential real estate prices.

Starting on Aug. 17, agents who list homes for sellers on widely used realtor databases won’t be able to offer any payments to buyers' agents.

That means the power to negotiate realtor commissions will shift away from agents in favor of buyers and sellers.
