In the last 2~3 years, the sale price of real estate has plummeted, and the news about the crime of rental fraud continues day after day. In this situation, the contents of the government’s recent measures about rental scam can be broadly summarized as prevention, support, crackdown, and strengthening of punishment. Among them, preventive measures include reducing the pre-tax rate subject to tax return guarantee from 100% to 90%, and preventing senior mortgage loans after the contract by providing information on each stage of the contract. If the landlord enters into a contract for the sale of the leased object with a third party during the rental(or lease) period, preventive measures such as requiring the tenant to notify the tenant in advance must be written in the standard contract and provided by the Association of Certified Realtors. On the other hand, it seems necessary to reconsider measures such as providing the credit information of the landlord to individuals such as authorized brokers or lowering the rental price rate in connection with the purchase of rental guarantee insurance. In addition, it is necessary to regulate certified brokers and real estate consulting firms that lead real estate transactions in close contact with the general public, and it is necessary to create institutional conditions for the general public to conduct real estate transactions transparently.
