Help customers and owners talk about housing prices. The client said to help me talk as little as possible. How should I reply to the customer?

As a buyer, of course, I want to buy my favorite items at a more favorable price, but if the seller wants to sell at a good price, the intermediary company also hopes that the buyer and the seller can complete the transaction as soon as possible. You can properly tell the seller that the buyer is sincere, see if you can lower it a little, and ask the buyer what the acceptable price is.
