Understanding BRRRR calculator report , need help

[Naor Biringer]

Hello to all,

calling all Investors, I am missing some expenses in the BRRRR calculator:

I cannot find where does the calculator takes in consideration the interest paid to the HML in the 6 months period to refinance

In the calculator sample attached I inserted 20% down on the HML for 6 months
both "Total project cost " and "Total Cash Needed At Purchase"  do not include the 6 months interest rate for the lender... 

I am probably missing out something, please enlighten me !

Thank you !!!
