A national registry designed to centralize information on and licensing for mortgage brokers and lenders has expanded to 14 states, according to the Conference of State Bank Supervisors (CSBS) and the American Association of Residential Mortgage Regulators, who first introduced the registry in January. On Monday, CSBS officials said that six more states — Connecticut, Louisiana. Mississippi, North Carolina, New Hampshire and Vermont — will begin using the Nationwide Mortgage Licensing System beginning July 1.
