What if the property company hasn't handled the real estate license for the owner so far?

Property ownership certificate has nothing to do with property management company. You should find a developer (who sells your house). When buying a house, the developer should tell you when you can get the real estate license. If the developer fails to perform in place, you can talk with the developer (all owners) to see what the specific situation is. If it is not a mortgage, you should get a certificate within three months of buying a house.
