It is simply far too tenant friendly. 

That's why I think investors are not your friend, you want retail buyers.Have you talked to the neighbors on all sides of you? 

Cabins are a different beast, I have 10 at another campground I built- Broad River Campground located in Mooresboro, NC (Has Cabins/Domes/RV Sites, Tent Sites)Cabins are sexy to talk about for sure, but you are now entering the hotel business my friend.

Please suggest if you think any other budget friendly ideas.

Abandon the Peurto Rico dream for now and look at more realistic/beginner friendly areas that still sport a large latin influence and strong rentals, like Florida (I've looked a little bit outside Miami..Boca Raton, Tampa, West Palm Beach, etc). 

Has anyone heard of a bank that is friendly to Self Directed IRAs and offers interest.I had Titan (have checkbook control as well) and switched as like you said, they don’t pay interest.

California is certainly not landlord friendly, as you have already eluded to.

I have a friend who runs a meetup over in Springfield, OH which is about 30 min away.

Then, narrow down from there and reach out to an investor-friendly agent you can find on the BP agent finder.
