Why is the price of second-hand houses in SouFun.com generally lower than that of Anjuke and Sina? (Shanghai second-hand house)

This is because the competition among real estate agents is fierce. They attract people who really want to buy a house to take the initiative to contact them by bidding at a low price, so as to prevent this valuable customer resource from falling into the hands of other intermediaries. In case the buyer resents the low bid of the intermediary, then other salesmen of the company will contact the customer. Anyway, as long as you have the will to buy a house and the budget is enough, then they will definitely earn an agency fee.
