It's extremely important if you're not in the right position to execute, buy, whatever.That said, if you're short cash, there are investors, hard money lenders, etc. 

All aspects of the rentals are going well and cash flowing good but I feel I am going to hit a ceiling shortly continuing in this manor.

But as i will manage the property i think will be better and easier the long term rent by at least one year contract for family from here, than make shorts rentals for tourists.

Or over a short term for flips? 

I've just been renting it out to long term tenants, but I'm wondering if I can legally do short term rentals (AirBnb) even if it isn't owner-occupied since it's zoned for commercial use?

I generally don’t like investing in RV parks because it’s too short term for me.

In short, we are seeking advice from anyone who has been in a similar situation.

Hi BP members, I'm getting ready to close on 3 family in the Weequahic area in Newark NJ and was wondering if anyone have any of their properties listed on Airbnb as I was thinking of converting 1 of my units into short term rentals. would like to hear any hurdles or successes people have had with Airbnb in any parts of Newark.

You want to look for similar options and see what they charge.If they are charging $1100-$1300 and have no vacancy you're in good shape, otherwise move on to another idea.So, to summarize a bit, this strategy works really well in areas where small apartments are in short supply and fairly high rents.

It's not mandatory that you attend @Wes Short, but if it's your first one, you may want to go so you learn and have more familiarity about the process.
