Now that you have the house ownership certificate, it means that the land and houses there are managed in a unified way. The so-called unified management means that the housing management department manages both the house and the land, so that your property certificate will contain information about the house and the land, such as the land number and the four boundaries of a piece of land (that is, where your community is built). Take a closer look at the real estate license yourself.
Another way is to look at the place where the official seal is stamped on the last page. Is the official seal stamped with the words "real estate" management department or "housing management" management department? The former also shows that the real estate license and land certificate are integrated.
4. If it's not the unified management of premises, don't refer to it! But I have never seen a real estate license without a land certificate!
