What type of lease allows negotiation of variables like rent and duration?

A negotiable lease is characterized by its flexibility, allowing both the landlord and tenant to negotiate critical aspects of the lease agreement, such as the rent amount and duration. This type of lease is beneficial for both parties, as it can adapt to the specific needs and circumstances of the tenant while providing the landlord with the opportunity to maximize their rental income and agree to terms that work for their investment strategy.

In contrast, a gross lease typically involves a set rent amount where the landlord covers most or all operating expenses, such as utilities and property taxes, and the terms are generally fixed without room for negotiation. A net lease, while it may allow some flexibility, primarily involves the tenant assuming responsibility for some additional expenses, which limits the room for negotiating core lease terms like rent or duration. A fixed lease defines specific terms that cannot be altered, providing no room for negotiation at all.

Thus, the negotiable lease stands out as the option that explicitly allows for the renegotiation of key lease terms, making it the correct answer.
