Renters earning less than $50,000 will share in the same property tax relief package homeowners are expected to get in the next year, Gov. Jon Corzine said yesterday. Corzine, speaking at an anti-poverty forum, also said he would support expanding the state rental assistance program and consider limiting how often affluent communities may sell off their legal obligations to build affordable housing in cities strapped for cash. Without rental subsidies and more housing opportunities in suburbs closer to jobs, thousands of people will continue to struggle, he said.
