Mr. Cooper has a B rating from the Better Business Bureau due to government action against the business. In 2020, the Consumer Financial Protection Bureau filed a complaint against Nationstar, which is what Mr. Cooper used to be known as, alleging that between 2012 and 2016 it unlawfully foreclosed on borrowers who had loan modifications. In 2021, the CFPB announced it was looking into an incident in which Mr. Cooper made duplicate withdrawals from thousands of customers' bank accounts due to an issue with its electronic payments vendor. According to Mr. Cooper, the lender worked with the impacted customers' banks to ensure they wouldn't be responsible for fees related to the error. This lender ranks low on J.D. Power's 2021 Primary Mortgage Origination Satisfaction Study, which measures customer satisfaction. However, it has strong reviews on both Zillow and Trustpilot.
