The assessor for this city is a County Authority, called Cook County.  

If so you probably have a way to evict them as long as you promise the housing authority you will rent to another Section8 tenant and then get the rents with the new tenants closer to market rent.

Generally speaking with probate records, you're usually looking for the estate administrator or executor i.e. the person who has the authority to make the decisions about settling the estate.

I am not an appraiser nor did i get my start in real estate as an analyst so i'm far from an authority on either.

@Melanie Campbell Did you sign anything authorizing them to charge you that amount?

The person renting to this occupant was never legal authorized to rent to them.

The taxing authority will value the entire property as one unit with very few exceptions :Some appraisal districts will parcel out one unit if it have a homestead exemption. 

yes standard practice the operating agreement and state LLC articles of incorporation This shows you have the authority to transfer your property

It sounds like you're going to need to go through probate to get your co-party to have the authority to sell.

They are not going to do so via voicemail/phone -- and hopefully they won't require borrower's authorization from you, but be prepared to address that requirement.
