A Chinese Phrase for Asking about the deposit: "请问押金是多少？"

"请问押金是多少？" means "How much is the deposit?" and it's the basic Chinese expression used for asking about the deposit. It's very handy when moving or looking for a place to live. To answer, you can say something like "押金是一个月的房租。" (The deposit is one month's rent). You can keep the conversation going by reacting with something like "好的，我明白了。" (Okay, I understand).
