Adding unit names/numbers to the property would help organise your list of properties in a better way. 

To add a unit to a property-

  • Go to Properties, by clicking on the Properties icon on the left hand-side menu
  • Click on the 'Details' tab of the property for which you would like to add a unit
  • Click on Add unit in the top right corner, add unit details as given in the screenshot below
  • Click Save

Please Note: This 'Add unit' option is shown only in case you chose the property type as multi-unit property while creating the property itself.
