I am considering living in one of the units myself.

5 units make a huge difference in NJ. 

Hi,Wanted to check what cash on cash return/cashflow I should expect for units in University City area (West Powelton, Powelton Village).

Run the numbers you may do better long term or renting as a whole unit.

I have one asst. manager doing book keeping weekly on over 400 units. 

Your first move at 18-21 should be house hacking (buying a small multi-family and renting out units).

We profit about $1200 a month from both units.

You could look for properties that are already getting solid rents in one of the units. 

Asking price is $998,0002 duplex units on 1 acre in good location.It's been on the market for a while, so I believe we could offer slightly above $900,000 and be considered.I would increase the rent after updating each unit.

If you are trying to raise a few hundred thousand to buy another 4-6 unit property, while I would not invest in someone with less than a year experience, I am guessing some of your pilot friends, other friends, or family members may be willing to chip in.Now, if you want to jump from a triplex to 80 units, raising 4-5mm of equity and another 4-5mm in debt, than I would just manage your expectations.
