Which of the following is NOT an implied promise in a land sale contract?

In the context of land sale contracts, an implied promise that a property has been inspected by professionals does not typically exist. Implied promises are generally understood assurances that are automatically included in a contract, even if not explicitly stated. In most jurisdictions, the law implies certain obligations on the part of the seller regarding the quality and ownership of the property being sold.

One of these implied promises is that the seller will provide marketable title, meaning the title is free from significant defects that would hinder the buyer's ability to sell the property in the future. Another implied promise is that the seller will not make false statements about material facts related to the property. Additionally, it is understood that the seller has the right to convey title, confirming that they are legally entitled to transfer ownership of the property to the buyer.

However, an implied promise that the property has been inspected by professionals is not a standard expectation in a land sale contract. Buyers are typically encouraged to perform their own inspections, and the responsibility for conducting such inspections lies with the buyer rather than the seller. Therefore, this lack of implication regarding inspections makes it the correct answer to the question.
