I was also involved in the development of a small (20K SF) self storage facility where I own a minority stake.

Nothing stops your father from renting out his house if he goes into a facility, there's no need to run it thru an LLC.

Cooking meth in the back of the property, stealing his mother's disability checks, etc.

A church builds a new facility and the old church sits there empty.Often a church just "doesn't make it" and they close the doors and it sits there empty.What would you do with it?

The home is in Cook County, IL--our tax assessor's website doesn't list home owner's and the software I've been looking to look up data hasn't turned up much either.Besides the CAD, what other places can I go to find a home owner's information?

I'll mostly be working in the Cook County area of IL, and any help would be greatly appreciated!

So far having a problem finding a facility that does not require them to be "empty." 

Multi-family, self storage, healthcare facilities, etc.

We have a Chicago, Cook County, and IL (IHDA) program. 

County records, look up the address of facility then they often show owners name/mailing address.
