thanks @Rong TanLooks like Hurricane Idalia will miss SWFL, with only minor impacts to that area. 

I always discuss investments with others in an investor club because other people might think of things that I might miss.

Don't miss any payments.Your question: "Suggestions on learning more about contract for deed?

And you don’t want to sell after going through all that trouble and miss opportunity.Here’s my take.  

Otherwise, you may be limited to doing deals that are less than or equal to the equity in your home, and miss out on some bigger opportunities.That said, fix-and-flip loans will have higher fees and interest rates than most HELOC's.

What is really missing are the numbers, or spreadsheets that can illustrate the savings. 

I've been searching for threads/experience purchasing via DSCR (using HELOC as down payment + rehab) and then cash out-refi at 6mo & pay off HELOC...am I missing something?  

I would appreciate any insights and additional things I may be missing.

With the limited info, I would say #1 is your smartest option but there are a lot of variables missing.

You are missing the point.
