BRRRR Calculator Please Help

[James Rodgers]

Hey all, I have been tinkering in the calculators for a while, but I do not think I am running the BRRRR calculators correctly.

My biggest question has to do with the rehab cost and the loan amount. 

For example: when I input a purchase price for a home at $100,000,Rehab for $20,000, and a 20% DP - the calculator is basing the DP on the $100k cost of the home. Is this how I should be working the calculator? Or should the rehab costs be factored into that DP amount?

I have no personal experience with a HM lender, but from listening and reading I believe most will do LTV anywhere from 70-90% and a lot of times consider the rehab costs into the loan. If so, shouldn't the DP on my calculation in this example be based on $120K ($100k purchase + $20K rehab). If this is in fact correct, how to I make sure the calculator is taking this into consideration?

Any help on how to work the numbers on the acquisition loan in the BRRRR calculator would be greatly appreciated.

Thanks!
