MISMO Calls for Participation in New Initiative to Develop Standard Commitment File to Speed the Exchange of Data

WASHINGTON, D.C. (December 9, 2025) – MISMO®, the real estate finance industry's standards organization, today announced a call for industry professionals to participate in the launch of a new initiative to develop a standard Commitment File.

“The Commitment File is essential to the selling of loans, yet today it is handled differently across the market. Establishing a standard will streamline operations, reduce manual effort, and speed the exchange of information between lenders and capital markets participants,” said Rusty Emory, CSMP, VP of Investor Delivery at PrimeLending. “MISMO invites the industry to come together to create a solution that will drive real modernization in the post-closing space.”

The Commitment File is a critical component in the post-closing phase of the mortgage life cycle, containing key information that is used in the selling of the loan and master servicing rights by the originating lender. The structure and transmission of this file vary widely across the industry despite its importance, which leads to inefficiencies, delays, and data quality challenges.

A standard Commitment File will reduce manual work and reformatting, improve data accuracy, and accelerate the exchange of information between lenders and capital markets participants.

The kickoff meeting will take place at the MISMO Winter Summit on Wednesday, January 14th from 9:00am-10:20am ET in the Secondary Community of Practice. Anyone is welcome to join the Secondary Community of Practice on the third Tuesday of each month from 3-4 pm ET to work towards this goal.

This effort will benefit a wide range of industry participants, including mortgage originators and investors involved in inventory delivery, secondary, and capital markets, as well as point-of-sale solution providers such as product and pricing analysts and integration specialists. Individuals interested in participating in this group who are already MISMO Members may join the Secondary Community of Practice collaboration site on MISMO Connect.
