Tennessee Code Title 45. Banks and Financial Institutions § 45-13-207

(a) All books and records required to be preserved by any regulation of the commissioner or required by any federal statute, regulation or regulatory guideline, as applicable to each licensed mortgage lender, mortgage loan broker and mortgage loan servicer, shall be preserved and made available to the commissioner, as provided in this chapter, for the time that the commissioner may by rule or regulation require, not to exceed twenty-five (25) months on all rejected applications and not to exceed twenty-four (24) months on loans paid in full. The licensee may cause any or all records at any time in its custody to be reproduced or preserved by itself or by any other person who agrees in writing to submit its operations to the examination of the commissioner to the extent that the operations directly affect the recordkeeping, by any microphotographic process, electronic or mechanical data storage technique or any other means. Any record reproduced or preserved by those processes, techniques or means shall have the same force and effect as the original record and be admitted into evidence equally with the original.

(b) Any licensee, after receiving the prior written approval of the commissioner, may maintain records at any location within or outside of the state.
