In addition to setting common goals and increasing communication, policymakers with a stake in housing should think creatively about ways to combine funding streams from different sectors or systems to support housing development. The pool of resources available for housing development should draw upon a blend of funds from all systems with a stake in ensuring that individuals have appropriate housing. Health, mental health, and homeless assistance funds are already being used in some jurisdictions; in recent years, state and local governments have been experimenting with innovative ways to use criminal justice funding to create set-asides within existing supportive or affordable housing projects.

Non-housing agencies may be able to contribute resources other than funding to increase the supply of affordable and supportive housing. Such resources can include unused land or buildings to offset the cost of land acquisition in housing development, political support in legislative proposals, or a convening role, bringing together relevant experts and policymakers to comprehensively identify resources.
