A lease agreement that designates the lessee (the tenant) as being solely responsible for all of the costs relating to the asset being leased in addition to the rent fee applied under the lease. The structure of this type of lease requires the lessee to pay for net real estate taxes on the leased asset, net building insurance and net common area maintenance. The lessee has to pay the net amount of three types of costs, which how this term got its name.
This type of lease can also be referred to as a “net-net-net lease” or a “hell or high water lease”.
