YES. YOU CAN BE THE ONLY ONE ADDING NEW PROPERTIES.
You would still need to submit properties in front end, but you can make the front end submission to work just for an account you own, and the rest of users will register just to send private messages / send booking requests / save favorites properties.
How to control who submits properties:
1. Go in Theme options GENERAL SETTINGS and setup no to option “Separate users on registration”
2. Register your own subscriber account in front end:
3. Go in Theme options GENERAL SETTINGS and in “Only these users can publish (separate SUBCRIBERS usernames with ,).” type the username of the new registered user.
To limit submit to more users, you must set the users with ,(comma) and no space.
If you added properties as admin you can edit them and assigned them to your new owner account.
Edit from Admin -Listings – Edit Listing – Owner responsible
What will happen after this setting is done:
Subscribers usernames listed in theme options – general settings will have the user dashboard with all pages (including submit)
All the other subscribers registered on the website will have limited pages in the dashboard (no pages for submit)
If you wish to supervise these “subscribers” accounts as admin, you can install the plugin called – User Switching – https://wordpress.org/plugins/user-switching/
