What is a good BRRRR ROI if CoC would be infinite?

[Gabriel J.]

What is a good ROI for a BRRRR? I know people use CoC which is great but if I am getting 100%of my money back out, how would I calculate a good return? Here is the info on the potential property:

Purchase- 50k

Rehab - 30k

Holding - 8k

ARV - 120k

Rent projection - 950/mnth

I would refinance 90k to get my money out which would make the mortgage around $635 a month PITI.

If I did a normal ROI calc I would only have around a 4% return. But cash flow would be $300 a month.

Any advice would be appreciated.
