Zack's actions of putting down a $12,000 deposit instead of $10,000 illustrate what concept?

Zack's decision to put down a $12,000 deposit instead of a $10,000 deposit demonstrates the concept of performance of the contract. In real estate transactions, when one party performs their obligations as specified in the contract, it reflects their intent to fulfill the terms agreed upon. In this case, by exceeding the required deposit amount, Zack is actively participating in the transaction and showing seriousness in his offer, which is an example of demonstrating performance.

In the context of a real estate purchase, performance is about completing the obligations outlined in the contract, and monetary deposits often signify that a party is committed to following through with their agreement. This action can strengthen Zack's position in the negotiation and indicate his genuine interest in finalizing the deal.

Understanding this concept is vital, as it highlights how actions like deposits can influence the dynamics of real estate contracts and transactions.
