Commercial Appraisal Data Standards

MISMO announces a 30-day public comment period ending on March 26, 2021 for recent enhancements to the Commercial Appraisal Dataset.  The commend period is intended to enable the public time to review and comment on recent dataset updates completed in response to feedback received during the initial comment period.   

This new dataset will facilitate the efficient exchange of commercial appraisal information, critical for underwriting and loss mitigation, between multiple industry participants. The new dataset was developed from a collaborative effort of the commercial real estate and technology professionals. Following the initial comment period the dataset was updated to include new building level data points; additions for non-multifamily property types and parties; as well as refinements to various definitions and enumerations.

The Commercial MISMO workgroup brought together stakeholders to create a better experience for conducting and exchanging appraisal information for multifamily and commercial properties. The workgroup released the stand-alone Commercial Appraisal Dataset specification along with several additional resources to facilitate ease of use and adoption including an implementation guide; logical reference structure; logical data dictionary (LDD); documented use cases in Excel; as well as sample XML files for each use case. Note that legacy MISMO commercial specifications will be updated to include new and modified data points, enumerations and structures associated with the new Commercial Appraisal Dataset at a future date.   

The public comment period is intended to afford workgroup participants who participated on the proposal notice prior to final release, at least 30-days notice in order to review the exchange and disclose any applicable Patent Rights (as defined by MISMO's 2018 Intellectual Property Rights Policy).  

At this time, MISMO also requests that any non-participant organization that may have any patent or patent applications, or other intellectual property rights that might be infringed upon by an organization that uses or is compliant with these proposed MISMO products, disclose at this time in writing.
