MISMO HMDA Implementation Toolkit

MISMO has released a set of products to help companies implement the new CFPB HMDA rules. These tools, collectively referred to as the HMDA Implementation Toolkit offer a comprehensive collection of guidance, mapping documents, and other information about the rule and the use of MISMO in meeting the requirements of the rule. In particular, the tools help companies build upon existing reporting requirements such as the GSE Uniform Mortgage Data Program (UMDP). By building upon already existing reporting requirements, companies should gain efficiencies in developing and maintaining their HMDA solution.The MISMO HMDA Implementation Toolkit is available as a member benefit to MISMO Members and is available to all other industry participants for a small fee. Additional information on the Toolkit is available on the  MISMO HMDA Implementation Toolkit page.

MISMO calls this collection the "Servicing Evidence of Compliance (EOC) Toolkit".  This toolkit will help companies implement the MISMO Standard for communication of a request/response conversation record for evidence of compliance purposes.
