Here are recommendations for a more effective tribal-housing program from the Assessment of American Indian Housing Needs and Program, a study commissioned by HUD from the Urban Institute:
Attach fewer strings but rigorously enforce the rules.
Require that funding goes mainly to low-income households that need it most.
Impose constraints that will discourage tribes from spending large amounts of money on a small number of families.
Phase in deregulation, so tribes with small or inexperienced staffs aren't overwhelmed.
Bolster training and technical assistance to improve the competency of tribal-housing staffs.
