Title Reports And 2nds

I have tried 3-4 different online property report sites but none of them seem to list the 2nds or other liens against the properties. Is this something that I should be able to find through these services, or do I have to go down to the courthouse for this data? I don't mind going down to the courthouse once I determine that I really want to pursue a property, but when just doing preliminary research, the courthouse is more time than I can afford. Thanks, Robert [addsig]
