March 31, 2026 — Cornerstone Servicing, a leading residential loan subservicer and division of Cornerstone Capital Bank, SSB, announced today that Fitch Ratings has upgraded its U.S. RMBS servicer ratings to RPS3+, reflecting Cornerstone’s continued operational strength, scalability, and consistent performance amid significant portfolio growth.
The upgrades include Cornerstone Servicing’s prime, home equity, and specialty second lien servicer ratings. In its rating action commentary, Fitch highlights the company’s highly experienced and tenured leadership team, strong operational execution, and robust controls across all aspects of loan administration and default management. In addition, the commentary notes that enhanced onboarding processes and proactive borrower communications have further supported growth while keeping complaint and error rates well below industry standards.
Cornerstone Servicing’s contact center performance meaningfully outperformed industry benchmarks, Fitch notes. Increased call volumes were handled efficiently, with minimal wait times and virtually no call abandonment. The agency cites the company’s continued investment in professional development and rigorous training programs as key drivers of operational quality and compliance adherence.
“Being upgraded by Fitch validates the strength of our people, the scalability of our platform, and our consistent focus on the homeowner experience,” said Toby Wells, President of Cornerstone Servicing. “As we continue to grow and evolve, we’re proud to be a subservicing partner that lenders and investors can trust and depend on—whether they’re looking to launch a unique loan product, grow and diversify their portfolio, boost customer retention, or keep pace with regulatory changes. We will continue investing in our people and platform to add value for people we serve in any market cycle.”
Cornerstone’s subservicing offer includes robust private label servicing options designed to deepen customer relationships and boost brand loyalty. Fitch’s commentary made note of the unique hybrid customer service offer the company launched in 2025, which gives banks, credit unions and IMBs the option to directly handle frontline customer service operations while Cornerstone Servicing provides contact center infrastructure, back-office servicing operations, and overflow customer service support.
Cornerstone Servicing supports a wide range of residential loan products, including first and second lien mortgages, home equity products including closed-end second liens, HELOC and HEI, non-QM (residential and business-purpose), construction and bridge loans, and other loan types. The company is licensed nationwide and remains in good standing with Fannie Mae, Freddie Mac, Ginnie Mae, FHA, VA, and USDA. Alongside Fitch Ratings, the company is rated by Moody’s Ratings and S&P Global Ratings, approved to service into securitizations by DBRS Morningstar and KBRA, and holds a Tier 1 FHA Servicer Rating from the U.S. Department of Housing and Urban Development (HUD).
