1. View the information in the auction announcement. Some auction announcements will indicate whether anyone is there.
2. Contact the auction company or intermediary and ask them if the landlord has vacated the house.
3. Go to the court to check the relevant case materials. When consulting relevant information, you can know whether the landlord has a record of being enforced.
4. Check the historical information of the property online, including whether anyone has used it.
Through the above channels, we can know whether the landlord vacates the house to a certain extent, but it is best to do as much investigation and understanding as possible in advance to reduce the risk of buying a house.
