BRRRR BP Calculator with Hard Money Lender

[Andres Ayala]

I am struggling to input the Hard money lender portion into the BP calculator. I plan on having the HM loan for 3 months. I am getting confused with the following

1.when putting down the down payment option for the purchase loan

2.interest only option

3.amortized over how many years? ( I am guessing one year but only need to hold the loan for 3 months)

Could someone please help me understand how to work this calculator with the HML? Thanks in advance hope that made sense.
