A buyer makes an offer on property and the seller accepts the buyer's offer. The buyer does not offer an earnest money payment in the offer. The contract is:

A void contract is one that is not legally enforceable from the moment it is created, typically due to a lack of essential elements such as capacity or legality. In this scenario, both the offer and acceptance exist, meaning the contract is not void simply because no earnest money was provided.

A unilateral contract involves a promise in exchange for an act, where only one party is obligated to fulfill their promise. This situation reflects a bilateral contract, as both the buyer and seller have obligations once the offer is accepted, making the unilateral classification inappropriate.

An unenforceable contract is one that, while valid, cannot be enforced in a court of law due to certain legal defenses, such as lack of written form when required. Here, the contract is valid and enforceable because it meets the basic requirements of offer and acceptance, even without earnest money.
