In general, when a real estate deal is concluded, it is necessary to pay a brokerage fee. The amount of the brokerage fee depends on the contents of the "Brokerage Service Agreement" concluded with the real estate brokerage company which asked to sell off the real estate.
However, in actual dealings, when there is a possibility that a sales contract will be concluded at a greatly discounted price, the seller may not pay a brokerage fee on the premise that the real estate brokerage company consents to it. Instead of not being able to receive a fee from the seller, the real estate brokerage company obtains a brokerage fee from the buyer or the real estate brokerage company on the buyer's side.
