Click the micro-menu located to the far right of the property listing.
Click on ‘Owners‘ from the drop down list.
Click on an Owner’s name will take you to their profile settings so you can edit information.
Change the setting for ‘Approved For This Property’ from Yes to No (see below in red).
Click the ‘Update Profile‘ button to save changes.
