Is the statement "I will buy your building for $5 million" considered a valid offer?

The statement "I will buy your building for $5 million" is considered a valid offer because it contains a clear and definite proposal to enter into a contract. A valid offer must express the intent of the offeror to be bound by the terms specified, which in this case is the willingness to purchase a specific item (the building) for a specific amount ($5 million). This clarity in both the subject matter and the price meets the essential elements required for an offer in contract law.

In contract theory, a valid offer does not necessarily need to be documented formally, although a written agreement is typically advisable for clarity and enforceability. The presence of a definite sum also indicates that the offer is not vague or ambiguous, which is a fundamental requirement for enforcing any contractual agreement. Clarity in the terms helps to minimize misunderstandings between the parties involved.

The other options either misunderstand the nature of an offer or incorrectly emphasize requirements that are not central to defining a valid offer. For instance, whether it is "official" or documented is not a requirement for an offer to be valid, and urgency is not a necessary condition for an offer either. Therefore, the clarity and specificity in the amount presented in the statement clearly establish it as a valid offer.
