The top U.S. watchdog agency for consumer finance Monday accused Rocket Homes, a unit of Rocket Companies, and a group of real estate brokerages of an illegal kickback scheme to steer mortgage applications to Rocket Mortgage.

"Rocket engaged in a kickback scheme that discouraged homebuyers from comparison shopping and getting the best deal," said CFPB Director Rohit Chopra. "At a time when homeownership feels out of reach for so many, companies should not illegally block competition in ways that drive up the cost of housing."
