Does the property have the right to detain the real estate license?

The property has no right to detain the real estate license. If he doesn't give it, he will go to the Housing Authority to report the loss and reissue it. As for the property fee, no matter whether you have moved in or not, as long as the house is yours, you have to pay the property fee, not to mention that you have moved in. You said that the patio on the second floor was closed, and the source of the problem was the developer, not the property. You can complain to the local street or the administrative law enforcement department by telephone. As long as there is no patio on his property right, it is an illegal building. If you refuse to pay the property fee, if you sue for the property, you 100% will pay.
