We added duplicate property function. It is on themeforest update queue. It will be available in a few hours, you will get an email when it will be ready for download.
I already have that plugin but it is not duplicating the property as it duplicate posts only ! but how to duplicate property
You can use this plugin: https://wordpress.org/plugins/duplicate-post/
It does exactly what you need, duplicates posts with all the meta data.
I have building with many apartments that share same description, features, rent.. etc so can I make one and duplicate/copy rather that creating new property for each?
If not then please consider adding this important feature in your update
