Excuse me, what information is needed for building (auction) to apply for real estate license and transfer, before it can apply for certificate? !

Your concept of expression is not clear, and there is no concept of construction back. An auction house is a house to be built or under construction. If it's soon, you won't get the room card. You may be talking about the demolition and replacement of houses. If yes, the following information is required to handle the real estate license: 1 property right replacement agreement; 2. Housing registration form; 3. Identity card; 4. Tax payment certificate, etc. The same area does not need to be taxed, and the excess part needs to pay relevant taxes. If the demolished person transfers it to the outside world, it will be taxed according to the second-hand house, and it will be fully taxed in less than 5 years.
