Int he mid-2010s, Nationstar Mortgage, known today as Mr. Cooper, emerged as one of the fastest growing nonbank mortgage servicers and lenders in the United States. Founded in 1994 and headquartered in Texas, the company built its business by acquiring servicing portfolios from distressed banks and expanding its lending capabilities through a network of call centers and correspondent relationships.
### Growth and expansion
– **Servicing acquisitions:** Nationstar purchased billions of dollars in servicing rights from large banks, giving it a rapidly growing portfolio of mortgage customers.
– **Lending division:** The company built a call‑center‑based origination platform that targeted refinance customers and expanded into purchase mortgages through correspondent partnerships.
– **Brand evolution:** In 2017, Nationstar rebranded its consumer division as Mr. Cooper to modernize its image and emphasize customer care.
### Why it matters
Nationstar’s rise illustrates how specialized nonbank servicers filled a gap in the post‑crisis mortgage market by offering flexible products and responsive customer service. Its expansion also created jobs in servicing operations, call centers and compliance roles at a time when many banks were contracting.
