ROI Goal: Multi-Family vs Single Family ROI Rates

[Eric Baumgarten]

I'm running the numbers on a properties, looking for my next buy and hold rental. I've found that there's a bunch of small multi family houses available - often 2-4 units per house. I've been told that shooting for at least 12% Cash on Cash ROI is good for single family rentals. While it's more difficult to find that kind of rate on a single family property, I do find it a lot easier to find that rate on multi-family properties.

Do investors tend to set higher cash on cash ROIs for small multi family units? If so, what's the reason? 

What cash on cash goals make a good baseline for multifamily properties?
