Residential Appraisal Data Development Workgroup

MISMO®, the mortgage industry's standards organization, invites the mortgage industry to participate in an effort to enhance its residential appraisal data standards. This effort will evaluate new types of property information that may be useful to the industry.  Importantly, the GSEs Uniform Appraisal Dataset (UAD) and Forms Redesign initiative is expected to utilize the resulting update to the MISMO standards. 

The increasing digitalization of the industry is resulting in the availability of increased amounts of information on properties.  To properly utilize these stores of new information, standards are necessary.  A significant update to the MISMO property standards is a possible result of this effort.

The GSEs UAD and Forms Redesign Initiative includes replacing existing GSE appraisal forms with new forms designed to support a greater range of property information.  It also includes the GSEs' updating the existing UAD to better support current industry needs and provide a more flexible, dynamic structure for appraisal reporting. A new UAD is needed because current GSE appraisal forms only support single family and condominium properties and do not accommodate new types of property information collected by new technologies. Fannie Mae and Freddie Mac are currently working together to update the UAD requirements to support all property types.   Updated appraisal forms and a revised UAD that utilize the updated MISMO standards are expected outputs of the GSE UAD and Forms Redesign Initiative.

MISMO's new Appraisal Data Standardization Development Workgroup will be responsible for creating an enhanced version of MISMO standards. This may include the addition of new data elements and/or structural changes to the MISMO model. 

Appraisers, appraisal management firms, organizations involved in developing appraisal related software and those involved in the collection, exchange or analysis of appraisal data are encouraged to participate in the effort. Mortgage industry participants do not have to be MISMO members to participate, but only MISMO members will be able to vote on the new standards.

If you are interested to participate with this group and are already a MISMO member you may join the collaboration site that has been established on "MISMO Connect".  If you are not a member of MISMO, let us know that you would like to participate by sending an email to .  For information on how to become a MISMO Member, see here.
