Which of the following is NOT required when advertising a lease?

The requirement for advertising a lease involves specific disclosures that inform potential lessees about essential financial terms and conditions associated with the lease. Among the options provided, the cost of leasing compared to purchasing is not mandated for disclosure in lease advertisements.

This is primarily because the focus of lease advertisements is to communicate the costs and terms specific to the lease agreement itself, such as the annual percentage rate of the loan (if applicable to financing the lease), the down payment amount or percentage required upfront, and the terms of repayment. These elements are crucial to understand the financial obligations involved in entering a lease.

In contrast, discussing the cost of leasing versus purchasing does not directly pertain to the lease's terms or obligations. This information may be helpful for consumers comparing leasing to buying but does not fall under the required disclosures that need to be presented in a lease advertisement. Hence, option D stands out as the correct choice since it does not pertain to the essential disclosures required by law when advertising a lease.
