It would be helpful if the deletion dialog window indicated the property name(s) so the user will make sure that only the expected property(ies) will be deleted upon confirmation. This is helpful for the accounts with high number of properties where accidentally more than one checkbox may be selected.
Ideally, the deletion workflow should be improved to avoid situation when somebody deletes a property another team member did not want to lose. The deletion workflow may look as:
1) the deletion marks the property Archived (like in AT). The archived properties may not be shown by default (like hidden report suites in AA).
2) the next action may be the actual deletion from the account (the user has to again check the box and delete)
