I noticed your link was actually to the previous Chicago Building Code "13B". 

At the time of construction the town sewer hadn't been extended to the neighborhood the property is found but now has one right in front of it.

You can build relationships with wholesalers who know your market and can provide you with leads on "Off-market" deals or you can use an agent to find something on MLS for you.

I have acquired my experience from working on my personal live-in-flips and building ADUs, as an owner builder and self-performing most of the work.

Lol, all jokes aside, that is a crazy request...I would tell them that I have no information on any drug use in the building.

I work with investors from all over the world investing in these neighborhoods, doing BRRRR and long term rentals, so Medina isn't that far at all and is a great advantage to be able to be in the area to make house hacking more possible. 

The property is rented by DCFS ( department of child and family services) a government tenant and are occupying the building for last 30 years and have no plans of relocating.

With commercial insurance, there are many ways to value a building, structure coverage and set deductibles. 

Look for the worst house in a great neighborhood with good school system or near major attraction.5.  

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620, many blemishes, but should have no evictions in last 2 years.
