Do this for a year or two and build up more cash, and then do it again. 

I am licensed in NY and CT so I was going to go to CT and buy a number of single families or a multifamily building but I am indecisive on whether I should go to CT or Jersey...or both.

On paper build your empire.  

Both are older homes, the 3/3 was renovated in the 80s.2/1 home is prime candidate for a tandem house out back or teardown and convert to Rowhome zoning, (properties were recently rezoned just across the alley tandem homes, ADU already zoned ok) 3/3 is newer, on a double lot, but my thinking is that I could hold these for a while, go through the rezoning process and sell both if/when the neighborhood continues to get hot enough for more density building, possibly work with a contractor friend of mine to get going in this direction, or try to do construction of tandem home behind 2/2 and then adu behind 3/3 home.Are there any resources for spreadsheets or analysis specifically in this realm/that I could show my financiers to calculate the projections on this?

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

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.

It is important to build a team that understands the unique dynamics of this market.Given your experience and substantial equity, sounds like you're in a prime position to capitalize on new opportunities. 

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.

I have a vacant rental that I am trying to use a property manager for the first time in Sonoma County (Windsor).
