Investigators are looking into challenges that American Indian tribes face in administering federal housing funds.
Representatives from the U.S. Government Accountability Office are visiting the Navajo Nation this week as part of the study mandated by Congress.
American Indian tribes or their designated housing entities receive some $650 million a year in Indian Housing Block Grant funding under the U.S. Department of Housing and Urban Development.
Officials from the Navajo Nation say challenges in developing homes include a lack of infrastructure, absence of large-scale land use planning and the tribal government's own review process.
The GAO's report won't be limited to the Navajo Nation. It's tentatively set for release before the end of the year and will include recommendations for addressing the challenges.
