Mr. Cooper

Mr. Cooper Group stands as a major player in the American residential mortgage landscape. Formerly known as WMI Holdings Corporation, the company, now headquartered near Dallas, Texas, focuses on the intricacies of home loans. Their services span from originating new mortgages to handling refinancing for homeowners across the nation. This specialization has positioned them as one of the largest mortgage servicers in the U.S., managing a substantial portfolio that reached roughly $937 billion in 2023, serving over 4.3 million customers. The company's journey saw a significant shift when it was acquired by Rocket Companies in 2025, marking a new chapter for the established mortgage servicer. This move integrated Mr. Cooper Group's extensive servicing operations into a larger, well-known fintech entity, aiming to further streamline the homeownership process for a wider audience. The acquisition signals a consolidation trend within the financial services sector, particularly in the housing market.[edit]
