You should join the West Suburban Land Lord Association in Berwyn.

If you haven't already, look into:Weekly webinars:https://www.biggerpockets.com/webinarOr the forums, or great guides and books:https://www.biggerpockets.com/real-estate-investin...https://www.biggerpockets.com/renewsblog/2015/01/3...https://www.biggerpockets.com/renewsblog/2014/01/0...http://get.biggerpockets.com/flippingbook/Or you can analyze deals to start getting practice before you actually jump in:https://www.biggerpockets.com/flip-analysisI would also suggest you look for local Real Estate Investing Associations or clubs meetings to begin networking with people in the industry.

I later viewed the property and realized it was not something I wanted to be associated with.

The Minnesota multi housing association has a meeting on November 10 which might be a good thing to bring to that group and discuss it.

My LLC is a standalone (not associated to my SDIRA) and my CPA filed my last returns under a Schedule C; if I associate a Solo 401k to an LLC, does this now make it a partnership (subject to Form 1065)?

You should definitely have reserves to cover your own living expenses(x 6 months) and the reserves for the rental property will be determined by the monthly costs associated with operation (x 3-6 months).  

I would recommend Illinois Association of Realtors 

So you may need these deposit cover the costs associated with this lease termination.

Also consider joining one of the local real estate investor associations.

Some condominium associations prohibit or restrict rentals.
