My question is if I made the HELOC go away from my cash reserves, could we then agree to seller finance the remainder and then use the cashflow from the STR to pay her plus give her a percentage to manage the property? 

I also don’t have a percentage, but in general - I have found Facebook Marketplace to have the “coldest” leads.

percentages are worthless.

A percentage of them may not be able to afford the new construction homes, so may instead buy in your neighborhood.
