Which of the following is NOT considered a common addenda form?

The answer identifies "Exclusive Right to Sell" as the option that is not considered a common addenda form. An addenda form typically modifies or supplements an existing contract, particularly in real estate transactions.

The other options listed are considered standard addenda because they each address specific legal or environmental concerns that may arise in a property transaction. For example, financing addenda provide terms related to financing arrangements and contingencies. Mineral reservations pertain to the rights over mineral extraction and ownership, which can be a critical legal issue in property sales. Lead-based paint disclosures are required under federal law for residential properties built before 1978, ensuring that buyers are made aware of potential health risks.

In contrast, the "Exclusive Right to Sell" is more of a type of listing agreement rather than an addendum. This agreement grants a specific agent the sole right to sell a property and is generally executed before a sale takes place, rather than modifying terms of an already established contract. Thus, it does not fit the definition of a common addenda form used to adjust existing agreements in real estate transactions.
