When the tenant breached the lease, the landlord had a duty to mitigate damages. That usually means making reasonable efforts to find a replacement tenant. However, the Nebraska Supreme Court has held that a commerical landlord fulfilled the duty to mitigate damages by seeking to sell the property rather than re-rent it. Hand Cut Steaks Acquisitions, Inc. v. Lone Star Steakhouse & Saloon of Nebraska, Inc., 905 N.W.2d 644 (Neb. 2018). The landlord's rejection of offers to rent the property did not violate his duty to mitigate damages given his reasonable efforts to sell the property. That meant the old tenant was liable for the rents up until the property was sold.
