Like all options contracts, the land lease option allows its holder to act on favorable future market conditions. The lessee may want an option for many reasons. If the future market value of the land is uncertain, an option will allow the lessee to extend a relatively cheap lease in a rising price environment. For corporations, lease options allow them to reevaluate operations based on leased land in the future, before locking themselves into very long-term contracts.
