Rookie Looking for Creative Financing Receptiveness in Market

I am interested in getting a beach house that is short term rented. My goal is to do some form of creative financing whether it be seller financed with a DSCR loan, or try to do a lease to own with an eventual mortgage assignment, or some other form of creative manuvre that avoids the steep down payment while also offering a fair compensation to the seller.

I am about 10 hours away from the area as well, for what it's worth and how that impacts this analysis  

How feasible are these ideas? How do people finance short term rentals like a beach house? Am I on the right track? 

Follow up, if I am on the right track, where are good starting points for building a team? I realize being in town and networking will be the most productive moves.
