I had to first evict the investor to gain possession from him, and then evict the tenant who was living in the property.  

I see you’re an accountant yourself and in New York, would like to gain your insight

Let's assuming that after backing out commissions from a sale at $520k, I use that since price since that would make it a 6.4% cap, then I net a gain of $155k, then I'd need to target a cash on cash return of 6.1% or higher (my current return on equity). 

What's the benefits of each.

Im a single person...I have never 1031 exchanged anything before, so not sure if id have to do this to buy another without owing a ton of taxes or could i sell it and just be safe of paying capital gains with the sale being under the 250k for single limit?

In addition, you're focusing too much on YOUR benefits (great tenant, eliminate vacancy), and ignoring the TENANT benefits (great landlord, quality unit, fully furnished). 

Those are valid and great, but there is a lack of social education on the economic benefits of real estate outside of BP. 

My partner will be more in charge of the labor work, doing what contractors aren’t needed to do while I help to save some money on expenses and rehab; and also just to learn and gain knowledge.

I was a Realtor for a short while but needed to get a steady income and health benefits back when my wife and I both started realizing our health issues were very unstable.

Not sure about Utah law you may want to read about it for your benefit.
