If you are the selling agent for a Building presale, you may want to mark your Building as Sold Out or similar remarks. Follow these steps to add these remarks to any of your buildings:
Go to your backend and then go to "Manage Listings", then to "Buildings". This will take you to your buildings' page.
Find the building you wish to change the remark on, and click on the Status dropdown menu that currently appears as "Active"
Select the Remark you want to put in this building. Once you click on it, it will autosave.
Another way to do this is to go to "Edit" on the building you are modifying and change the Status/Remark from there.
