At some point if you're doing well, maybe turn the first one into STR or LTR, and do it again.   

The property had a first mortgage, as well as a second mortgage, both from the same purchase money lender.After receiving the trustee’s deed and recording it, I discovered two “Independent Solar Energy Producer Contracts” recorded against the home.

So this is some kind of communal organization - there is a "mentor" at the top, and a bunch of "mentees" who do work for each other/for the mentor.Hopefully the asset is all in your name and your name only. 

If we do a Self Storage development we expect a 400% COC return.  

Well, for what?

You sound very organized for a first-time flipper so it looks like finding that mentor is paying off.

RTR has treated me so well I haven’t felt the need to try anyone else.

Feel free to inquire about their staff qualifications if it's a larger organization.2.

I lived well below my means, worked a full time job for years while doing this on the side, persisted when others did not... and now I am enjoying the fruits of my labor.  

If you are backing out of Florida because the properties aren't doing as well you like, why would you look for more units in a similar area and think the numbers will work there?
