MITS Data Models

NMHC launched the Multifamily Information Transaction Standards (MITS) initiative to improve operating efficiencies for rental housing by developing data models and leveraging data exchange technologies. Through MITS, data transmission among software systems, both within and between organizations, is facilitated through Application Programming Interfaces (APIs) and Extensible Markup Language (XML) to allow systems to communicate in key operational areas.

RETTC is now working to modernize and update MITS by bringing together rental housing providers and suppliers to collaboratively identify opportunities for operational efficiency and transparency that benefit renters and housing affordability.

MITS is freely available for download and its use is completely voluntary.

Property-Marketing/ILS 5.0 Mapping Implementation Tool Released

April 2, 2025

The Real Estate Technology and Transformation Center (RETTC) today announced the release of a MITS Mapping Implementation Tool, aimed at helping housing providers and technology partners adopt and implement the new charge classifications in the MITS 5.0 data model to enhance fee transparency.

The revised data model includes updated fee classifications that support transparency in communicating the total cost of renting a home—including fees—to prospective and current residents. The data model updates were developed in collaboration with leading technology partners and housing providers as part of RETTC’s MITS Working Group to simplify operations, reduce errors, and improve resident experiences. For housing providers, this means greater efficiency and alignment across platforms. For renters, it means increased clarity and confidence when choosing their next home.

The updates to MITS are well-placed to serve as a notable example of the ways housing providers and technology partners are working to streamline operations, lower costs, improve transparency and ultimately benefit renters.

MITS is freely available for download and its use is completely voluntary.

If you have any questions, please email MITS@rettc.org.
