There are many problems with using the relationship of a friend's father as the president of a real estate company to buy a house at the internal employee price. It is not recommended to do so: From a moral perspective, this behavior may involve improper use of relationships for personal gain, which violates the principle of fairness and justice. From the perspective of company regulations, if the real estate company has clear internal employee home purchase qualifications and processes, non-employees obtaining discounts through such relationships are illegal operations, which may lead to chaos in the company's internal management, damage the interests of other employees and the company's normal operating order. Moreover, this behavior may trigger a series of potential risks, such as subsequent disputes, and even bring unnecessary trouble and reputational damage to friends and their father. If you are really interested in the company's real estate, it is recommended to proceed through formal and legal channels, such as participating in public sales activities, negotiating transactions with developers in accordance with market rules, etc.
