When using Biggerpockets Rental Property Calculator?

[Joshua D.]

So when running my numbers on Biggerpockets Rental Calculator.When i Initially buy my properties i use my open lines of credit at 5% interest. Would that be considered using cash or loan? So in the section with loan details would i enter cash purchase or the amount of loan i used? I use all my cash from rent money then the big lump sums i cant come up with i use my lines of credit? How do i plug the numbers in to calculate for correct COC Roi and CASHFLOW? What number am i looking at that is most important? Cashflow or COC roi? Any Suggestions or advice would be great.
