The Johnson City Development Authority Has Received A Revenue Boost From The John Sevier Center. Rent Income Is Up 65-Percent Or 750-Thousand Dollars Per Year. This Is Due To The U.S. Department Of Housing And Urban Development’s Approval Of A “Mark Up To Market” In Rent At The Center. The Additional Revenue Is Not Coming From The Tenants, Whose Rent Is Income Based. It’s All Coming From HUD Who Now Values The Apartments At More Than A Thousand Dollars Per Month Each.
