I found a mobile home park in a growing town that is vacant. 5 acres- 16 established sites.

However, if you have the space, I would rent one of those mobile "pods" used for storage.

I've thought of buying a few airstreams to Airbnb, building a tiny home to rent out, storage units, or pouring a few slabs for RV/Mobile homes.

Are you using some kind of reverse look up service to get their mobile #? 

I’ve seen self storage facilities built from shipping containers and I’ve seen RV and mobile home parks bring them in to lease for additional storage.I suspect your greatest hurdle will be not offending your municipal government and neighbors.  

Currently has a red tagged mobile home on it.

But just like a single-family home, mobile homes are the same way.

Unless they are putting a HUGE amount down, this is either a mobile home or lower-end property. 

Hi, new to the community and was interested in opinions about the Rochester, NY/broader upstate market (prices and taxes both seem to eat into return prospects) as well as thoughts from anyone with knowledge of the Venice, FL (and surrounding) as well as Mobile, AL markets.  

I could get a significantly better return if I were to invest that money outside of the Bay Area and continue to rent here.The other factors involved are how mobile you want to be.
