Did a light rehab on the 3rd unit - fresh coat of paint and new carpeting.

Either you or your contractor can draw them, but I recommend having your contractor do it since they probably have a better understanding of building codes.And yes, if you want it to be considered part of the livable space you will also need HVAC and electrical (lights and receps).

Knowing that I am new to apartment investing , what is something that I could implement into my syndication that would encourage you to invest as a LP ?

I've addressed even the most minor issues like changing light bulbs when I can easily put it on the tenant. 

More than anything, meetups connect me to likeminded people, and give me insight on how various people implement strategies to find success in their own real estate investments.

Other than this, with showings: make sure the lawn is manicured, all lights are on while touring, window shades open, and maybe a handout with a short list of neighborhood amenities could be helpful!

Spiders, no lights, and the smell.

Initially, when I started investing in RE everyone I approached with an intent to form a partnership with to spread/share risk and learn with was a bit timid.I shared how I like to buy properties under market rent with deferred maintenance because I am able to do relatively light rehabs and raise rents to top market rent value. 

If the situation becomes dire, implement a progressive water charge.

To demonstrate my technical competence, for my personal house I built a steam shower, installed radiant barriers with rock wool, and a wood stove insert with bathroom radiant heated floors and re-designed radiant floor heat zones, cutting winter energy consumption to 1/8, installed a whole house fan cutting summer energy to 1/2, extensive localized landscaping leading to a reduction to 1/8 the yard work, plus random quality of life improvements like wifi switches, heated floors and toilet seats, skylight install, exposed structural beams, and master bedroom laundry including electrical and plumbing, cathedral ceilings with skylights, a steam shower with wifi controllable lighting and music, concrete countertops, etc.
