Finding Owners of Distressed/Vacant Properties when nothing appears on the County Auditor's Website

[Stephanie H.]

I drove for dollars and I have a list of of addresses.  I went to the county auditors/tax assessor's website to find the owners.  I've ran into a couple of properties that are not listed on the county auditors website or google for that matter.  I was able look on google maps to find the property, but no other information was listed.  My question, how do i find the owners for these properties if their is no data trail on the county auditors website?  one property is a single family and the other is an apartment.  any insight is greatly appreciated.
