A down payment and a deposit are different things, although they are both part of the buying process.
A deposit is a sum of money that is paid by the buyer to the seller to secure the purchase of the property. The deposit is paid when the offer is accepted and is kept until the closing of the sale.
On the other hand, a down payment is a portion of the purchase price that the buyer pays upfront in cash or through financing to secure a mortgage loan. The down payment is typically a percentage of the total purchase price of the property and is paid at the time of closing.
