Analyze BRRRRs? The numbers always look stellar!

[Michael Koch]

Hey folks, I'm looking for some help on metrics for analyzing BRRRRs. Using my standard CoCs, Debt Service, ROIs, etc, I'm struggling with how to not have the numbers look amazing. With no money in or very little, ROI goes to infinite soooo, what am I missing? Do others have better methods? Or should I purely look at cash flow and call it a day?
