Multi-Family Cash Flow Seeking Advice

[Matthew Haase]

I am currently looking at a 4 unit MultiFamily that will be upwards of 900K. How much cash flow should i reasonably want (after accounting for vacancy, repairs, capex) that makes a deal like this worth it? I see Brandon in the BP vids looking for 100/unit and think that is good for his area but would be fairly low for a mortgage this high. I am using a VA loan so I will have no money down into the property so my cash on cash ROI is odd to conceptualize for me in a way that makes sense. Any advice from some of you more seasoned investors would be greatly appreciated! Thanks!
