Some neighborhoods such as Caswell Hill, Mayfair, Buena Vista, Varsity View, Avalon, Queen Elizabeth and a lot more. 

I am using Elizabeth Moira-Sickels for a short-term rental and happy so far...she specializes in AirBNB: www.elizabethmaoraLLC.com

@Vince Padalino I am starting off in the Elizabeth area and probably making a mistake trying to manage this duplex myself but more to the fact I am going to need to replace the heating system (steam boiler), do you have any companies that you can recommend for this work and or HVAC? 

Hey Elizabeth, yep... not really hard to do. 

You said you live in Union county, Elizabeth and Plainfield are good options for rentals.

And lastly, you would be better off checking out all the arbitrage info Michael and Elizabeth Chang provide on their YouTube channel, social media, website, etc.Best of luck on your endeavors!
