Deposit explained
When you make an offer on a home, you typically include a deposit, a sum paid shortly after the offer is accepted. It signals that you are serious and gives the seller some security that you intend to complete the deal. The deposit is normally held in trust, often by the listing brokerage or a lawyer, until closing.
The deposit is part of your down payment, not an extra cost. At closing it is applied toward the amount you owe, so the balance of your down payment and the mortgage make up the rest of the purchase price. If you back out without a valid condition, you may forfeit the deposit; if a genuine condition fails, it is generally returned.
