Go to the property and let the owner call.

General property companies will keep the phone number of the owner, so as to contact the owner to inform related matters, such as community activities, housing facilities failure, arrears and so on. The owner's telephone number belongs to the category of personal privacy, and the property cannot be disclosed to others without authorization. If the owner does not leave a phone number in the property, it is normal for the property to call for the phone number.
