Mr. Cooper Headquarters Address, Corporate Office Location, and Contact Details

About

Nationstar Mortgage LLC — operating publicly under the brand name Mr. Cooper — is America’s largest non-bank mortgage servicer and originator, headquartered at 8950 Cypress Waters Boulevard, Coppell, Texas 75019 — in the Dallas–Fort Worth Metroplex, approximately 15 miles northwest of downtown Dallas. The parent holding company, Mr. Cooper Group Inc. (NYSE: COOP), is a publicly traded entity; Nationstar Mortgage LLC is its primary operating subsidiary and the legal entity that holds mortgage servicing licenses across all 50 US states.

Nationstar Mortgage was founded in 1994 and grew through the 2000s and 2010s into one of the largest mortgage servicers in the United States — acquiring mortgage servicing rights (MSRs) from major banks that were downsizing their mortgage operations in the wake of the 2008–2009 financial crisis. In 2017, Nationstar Mortgage Holdings rebranded its consumer-facing business to Mr. Cooper — a move designed to emphasize a warmer, more customer-centric brand identity in an industry where consumer trust was low following the mortgage crisis. The corporate parent was subsequently renamed Mr. Cooper Group Inc. in 2018.

As of 2024–2025, Mr. Cooper Group services a mortgage portfolio exceeding $900 billion in unpaid principal balance (UPB) — making it the largest non-bank mortgage servicer in the US, ahead of Pennymac and loanDepot — serving approximately 4 million+ homeowners. CEO Jay Bray has led the company since 2012, making him one of the longest-tenured executives in the mortgage services sector. In 2025, Mr. Cooper Group announced a proposed merger with Rocket Companies (NYSE: RKT) in a $9.4 billion all-stock deal — a transaction that, if completed, would create the largest mortgage company in the United States by combined servicing and origination volume.
