Which item would not be covered in the TREC promulgated form for buyers leasing a property before closing?

The reason the correct answer is B, where the lending institution is named, is that the TREC promulgated forms primarily focus on the specifics of the transaction between the buyer and the seller, as well as the terms of the lease agreement between the buyer and the landlord, if applicable. The forms are designed to regulate the rental terms in connection with the purchase of a property, which includes elements like the rental amount, the length of the lease, and maintenance responsibilities.

However, details about the lending institution, like which bank or lender is providing the financing for the purchase, typically fall outside the scope of the lease agreement and are documented in other loan-related paperwork. Thus, including the lending institution's name doesn't pertain to the terms directly related to leasing the property before closing.
