How to find the owner's information, for example, if a house is empty and no one lives in it, I want to rent it, how to contact the owner?

You can find a residential property. Generally, residential properties have the contact information of owners, which is convenient for maintenance matters, such as changing water supply and drainage upstairs and maintaining heating.

The second is to contact the community or the street office. With any luck, we may be able to contact the owner.

Ask her neighbor again. Generally, people who have contact will leave their phone numbers, especially when they go out for a long time, and they will ask their neighbors to help them look after the house. Maybe asking them will yield unexpected results.

The last resort is to put a small advertisement on her door, such as: "I want to rent your house, not an intermediary, contact information and so on ..."
