BRRRR Calcs using HELOC as acquisition funding source

[Nathan Haws]

I understand that using my own equity/cash to make the purchase goes against some of the basic BRRRR principles, but I want to ensure that my numbers are accurate when using HELOC funding for the acquisition. I can still get the competitive advantage of a cash offer with HELOC funds, but I believe I should be treating it like an interest only loan without any down payment for Cash Flow and ROI calcs.

A HELOC just seems more practical for a new investor, with a good amount of equity in their home and good credit, but without a lot of connections to private/hard money lenders. 

Thanks for your help!
