The doctrine of mitigation of damages creates an obligation on the part of the landlord to use such diligence as would be exercised by a reasonably prudent man under similar circumstances to re-let the premises, if possible, in order to mitigate damages resulting from the tenant's breach of lease. State v. Boyle (1976), 168 Ind. App. 643, 646, 344 N.E.2d 302, 304. The obligation exists even if there is no mandatory re-letting clause in the lease. See Hirsch et al. v. Merchants Nat'l Bk. (1975), 166 Ind. App. 497, 336 N.E.2d 833. Further, courts have recognized and enforced the doctrine of mitigation of damages while at the same time sustaining savings clauses.
