NationStar Mortgage LLC — Registered Agent at 2710 Gateway Oaks Dr, Sacramento
Serve NationStar Mortgage LLC (Mr. Cooper) via CSC at their Sacramento registered agent office — fast, flat-rate pricing.
NationStar Mortgage LLC is the legal entity behind the Mr. Cooper brand — one of the largest non-bank mortgage servicers in the United States. California litigation against NationStar is concentrated in wrongful foreclosure, RESPA violations, and loan modification fraud: servicer errors during the modification review process, dual-tracking claims, and failure to provide required disclosures account for a substantial share of filings. Predatory servicing claims — particularly around force-placed insurance and improper escrow accounting — have also generated class action exposure in California federal and state courts. The operating entity in California complaints is NationStar Mortgage LLC, not the Mr. Cooper brand.
