Those numbers are about 3x too low for any areas that will appreciate in Florida for what you are planning to do. Also, Florida is the toughest state on unlicensed contracting in the country because of what happened after Hurricane Andrew. If you aren't licensed in FL as a contractor I wouldn't count on swinging in and doing the work yourself being as easy as it seems. There are places in Florida where you can get closer to your numbers, but it is slow there and deals may be out there, but appreciation is low. You could look at an area like Deland which is more rural, but rents are ok.
A lot of the terms you are using are BP-friendly, but won't get you far investing in out-of-state markets. The BRRR method and house hacking and neighborhood grading systems are not always applicable or understandable across the board for who you will work with in each market. And if you don't have a marketing strategy, counting on owner-financed is not wise. That takes specific marketing and targeting, as will all areas where you will need to send a lot out to get very few leads and then they will want to know you are local and available.
