Commercial leasing, whether by landlords or tenants, is not for amateurs. Or sissies. There are provisions that are critical and must be carefully drafted, even if they seem wordy.

The disposition of leasehold improvements at the end of the term is of significance to both lessor and lessee. Landlords may require that all leasehold upgrades remain, or require that they all be removed. Either could be costly.
Negotiation skills can be as important as legal talent.
