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 lacks legal effect from the outset, often due to illegality or lack of capacity. In this case, the contract between the buyer and seller has not been rendered void simply because the earnest money was not offered. The contract remains valid since all parties have agreed to the terms, regardless of the earnest money.

A unilateral contract involves a promise in exchange for a performance, where only one party is bound to act. In this situation, both the buyer and seller are mutually bound by the acceptance of an offer, making it a bilateral contract rather than unilateral. Therefore, this option does not accurately describe the nature of the contract at hand.

An unenforceable contract is one that, while valid, cannot be enforced in court due to certain legal defenses. In this case, the contract is not unenforceable simply because earnest money was not provided. Such a payment is often considered a good faith gesture rather than a legal requirement for the validity of the contract.
