_____ are for the personal benefit of the buyer only.

The correct answer is implied covenants. Implied covenants are typically terms assumed to exist in a contract or agreement based on the nature of the transaction and the intentions of the parties involved. In real estate, these covenants often pertain to the quality and condition of the property being sold, ensuring that it meets certain standards for the benefit of the buyer. This means that they are designed specifically to protect the buyer’s interests, providing assurances regarding the property that may not be explicitly stated in the contract.

In contrast, express warranties are explicit guarantees provided by the seller about the property's condition or performance, and while they benefit the buyer, they are not solely for the personal benefit of the buyer as implied covenants are. Contingent fees relate to payments that depend on certain conditions being met, such as obtaining financing or completing inspections, and do not directly pertain to the benefit of the buyer alone. Liability waivers are agreements that release one party from liability, and while they can also benefit a buyer, their primary purpose is to limit the seller's exposure to legal claims, not to exclusively enhance the buyer's interests. Hence, implied covenants are best understood as benefits specifically for the buyer in the context of property agreements.
