How are yal finding LLC owners?

[Allison Meggison]

I've been struggling to find LLC owners because when I go to the county site it shows a company name usually. I look up the company on the secretary of state site and sometimes its there but most of the time it's not. I also skip trace the mailing address but it's usually a suite number in a plaza. What is the best way to find out who these owners are? What about unit count and renovation status for these buildings? I'm looking at apartment buildings in Phoenix. (Yes I've searched the forums for answers.)
