HELOC and the BRRRR calculator

[Nancy Stark]

If I am using my HELOC at 4.01% interest to purchase a SFH outright, how do I use the BRRRR calculator?

When I use the Rental Property calculator, the numbers make sense, but when I use the same figures in the BRRRR calculator, it shows no cash flow and a low cash-on-cash ROI.

Example:

Purchase Price = $100K

Rehab = $30K

ARV = $200K

Rent = $1250/mth

using a $130K HELOC @ 4%

I am getting a negative cash flow, with a Inf% ROI w/ the BRRRR method. What am I doing wrong?
