It is theoretically possible to use your friend's father's relationship as the president of a real estate company to purchase a property at the internal employee price, but the specific situation depends on several factors: 1. **Company policy**: Different real estate companies have different housing purchase policies. Whether employees or relatives of employees are allowed to purchase a property at the internal employee price depends on the company's regulations. 2. **Personal relationship**: Even if the company policy allows it, whether the purchase can be successful is related to the attitude of your friend's father and the management of his company. 3. **Legality**: The method of purchasing a property needs to be legal to avoid any possible conflicts of interest or violations. 4. **Market conditions**: If the demand for the property is high, the housing purchase needs of other internal employees or executives may be given priority. If you consider this option, it is recommended to have a frank communication with your friend and his father, ask if it is possible, and understand the company's relevant policies.
