On October 27, the CFPB issued warning letters to 44 mortgage lenders and mortgage brokers informing them that they may not be in compliance with certain provisions of the Home Mortgage Disclosure Act (HMDA) and Regulation C. The warning letters state that the recipients may be required to collect, record, and report housing-related lending data, and that they may be violating those requirements. Under HMDA, financial institutions that meet certain criteria are required to collect and report data related to their housing-related activity, including home purchase loans, home improvement loans, and refinancings they originate or purchase, or for which the institutions receive applications. The letters recite HMDA’s coverage criteria for lenders who are not banks, credit unions, or savings associations, suggesting that the CFPB is particularly concerned about HMDA compliance for non-depository mortgage lenders. While the letters state that the CFPB has not made any determinations that the recipients are in violation of HMDA filing requirements, the letters urge recipients to review their practices to ensure compliance with the relevant laws, and encourage recipients to advise the CFPB if the institution has taken steps or will take steps to ensure compliance. The letters advise recipients of the CFPB’s authority to impose civil money penalties for noncompliance with HMDA. In October 2013, the CFPB fined a bank and a nonbank mortgage lender for filing inaccurate HMDA data. In October 2015, the CFPB finalized a rule amending the HMDA reporting requirements under Regulation C, with the majority of the provisions taking effect on January 1, 2018.
