Mortgage Compliance Dataset (MCD)
MISMO® published the MISMO® Mortgage Compliance Dataset (MCD) Version 2.0 as Candidate Recommendation status on December 11, 2025.
The MCD specification replaces the fixed format Loan Examination File (LEF) with an XML schema-based version tied to version 3.6.0 of the MISMO Reference Model. As a companion to the MCD specification, MISMO also published a schema file to assist with implementation efforts.
Utilizing MISMO data terms and structures allows users to leverage the same data terms used in other agency reporting and data exchange across the mortgage industry and the mortgage lifecycle. This enhances data accuracy, creates processing efficiencies, and allows the file to be updated more easily as needed over time.
The enhanced dataset, developed in partnership with the Conference of State Bank Supervisors (CSBS), represents a major step forward in modernizing and automating mortgage compliance examinations. By allowing regulators to leverage technology and lenders to identify and remediate issues before examinations, the MCD significantly reduces friction in the exam process and streamlines oversight across the system.
