Whether the Dalian self-service terminal needs the property stamp depends on the specific situation. If the inquirer can provide valid identity certificate and authorization certificate of real estate inquiry, then there is no need to stamp it. However, if the inquirer can't provide these certificates, he needs to fill in the application form on the self-service terminal and affix his official seal or signature.

When filling in the application form, you need to provide the identity certificate of the inquirer and the authorization certificate of the real estate inquiry. If the inquirer can't provide these certificates, he can also choose to go to the window of Dalian Real Estate Registration Center for inquiry.

To sum up:

Whether Dalian self-service terminal needs to stamp when inquiring about real estate depends on whether the inquirer can provide valid identity certificate and authorization certificate for real estate inquiry. If you can provide these documents, you don't need to stamp them. However, if you can't provide these certificates, you need to fill in the application form on the self-service terminal and affix your official seal or signature. If you still can't complete the inquiry, you can go to the window of Dalian Real Estate Registration Center to make an inquiry.
