What does the group purchase fee generated by buying a house through an intermediary mean?

Group buying fees push up house prices in disguise. Let me give you an example. Assuming that the house price is 500,000 yuan and the price rises by 300,000 yuan, the group purchase fee is set at 6,543.8+million, and the preferential condition is to pay 6,543.8+million yuan. So how much will the last buyer pay? The answer is 700,000. At this time, there was deceptive behavior. The intermediary will say that the house is worth 800,000 yuan, but the transaction is 700,000 yuan, because the group purchase fee is 654.38+ 10,000 yuan. The management method is very simple, that is, when buying clothes, the price is raised first and then discounted, and the space with difficult supervision is used to avoid responsibility.
