In real estate transactions, there are indeed some unethical means that may cause buyers or tenants to misjudge the true condition of the property. These means include but are not limited to: 1. **False advertising**: exaggerating the advantages and features of the property, using embellished language in advertising or display, and hiding defect information. 2. **Concealing defects**: deliberately not disclosing to buyers or tenants the defects of the property, such as leaking pipes, mold, insects, etc. 3. **Not providing a true house history**: concealing the past record of the house, such as past repair history, accidents, etc. 4. **Falsifying documents**: providing forged property documents, inspection reports or permits to conceal the true condition of the property. 5. **Careful arrangement**: temporarily decorating or arranging the house to cover up problem areas during display to give people a good impression. 6. **Selective display**: only showing the highlight areas of the house, while deliberately ignoring or covering up problem areas, causing misunderstandings by buyers or tenants. 7. **Exaggerating the surrounding environment**: falsely promoting the facilities and services of the surrounding environment, and may claim that there are schools, supermarkets, etc. nearby, when in fact they are far away. 8. **Use of industry jargon**: Using professional jargon to mislead non-professional buyers, such as using "open space" to describe a less practical layout. 9. **Deceptive pricing tactics**: Setting prices too low to attract buyers' attention and then leading them to pay extra. 10. **Fabricated competition**: Exaggerating other buyers' interest in the property to create a sense of urgency and make buyers rush to make a decision, thereby ignoring a detailed inspection of the property. In all cases, buyers and tenants should be vigilant, conduct comprehensive due diligence, and seek professional advice to avoid being deceived.
