HELOC $ as Down Payment / Analysis Calculations

[Janel Briones]

If I am using $ from a HELOC, as a down payment on a property, how would I include that expense in my analysis?

Should I be conservative and include the P&I, or just the Interest, as in the draw period, payments required are interest only?

Would I consider this down payment monies, from HELOC loan as "cash" , for COC return?

Where should I plug in this HELOC payment in the rental property calculator, or manually add it to?
