Livonia Public Schools officials will use three of its closed schools to rent and take in student overflow from other schools. The closures came as part of the district's cost-cutting program titled Legacy Initiative. Michael Addonizio, Wayne State University professor of education policy, says many school districts are becoming landlords. "For a long time, up until the 1980's, this notion of renting schools didn't occur to school districts. Then, they realized it's a good source of revenue."
