official website
An internet page controlled or sanctioned by the owner of the object whose information it provides.
An official website is an internet page controlled or sanctioned by the owner of the object to which the data pertains. Because the owner is presumed to have good access to data about a property, this source is generally accepted over professional or user-generated websites.
Owner authorization is the distinction. A professionally produced page can discuss the same property without being controlled or sanctioned by its owner.
An official page can contain announcements as well as statements about existing conditions. Its authorized origin does not make a proposed future condition an accomplished fact.
