Not email.

Any benefit from sending an email copy so they get it faster ?

Here are the top things to do: 1) have really nice photos and lots of info about the property 2) have very competitive rates and even better is just below your competition 3) answer your phone and emails all day every day--people want an answer quickly.

A legal document would be written absolving me from any obligations.

I've already got 2 mortgages sitting on my credit record, and gotta show tons of documentation proving that those are rented out.

I tried to list and email blast my available properties on loopnet, propertyblast.com and www.buzztarget.com.

You will probably see multiple documents all recorded upon the recording of the sale to you.

I just emailed the listing agent on zillow and asked for some comps.

The Assessors Office can help, or... they can call the "title plant" of a title company there (Chicago Title) and ask if they will email the parcel map to them.

You can see an attorney to draw up LLC documents.
