Rumor has come. Recently, there have been a number of housing advertisements on the short video platform. The agent who released the housing claimed that he could receive the "housing subsidy" when buying a house in Shanghai, with the amount ranging from 200,000 yuan to 300,000 yuan. An intermediary declared: "Shanghai Songjiang New Town has a total price of 760,000 yuan and a housing subsidy of 250,000 yuan." "After receiving the subsidy, you can buy a 78-square-meter house with a down payment of 50,000 yuan."

Second, the so-called "subsidy" is actually that developers lend money to buyers to pay down payment, and buyers have to pay interest. Third, the commission returned by the intermediary to the buyers is packaged as a "subsidy".
