Evaluating small multi-family

[Walter Ciucevich]

I'm now on my 9th property and up until this point they're all single family homes. I know people speak against it, but I use Zillow to search recently sold comps to help me determine an ARV on these homes and have been for the most part spot on, because I am conservative.

I want to move into small multi-family, 2-8 unite. I can't find comps as easily and I'm not sure if that's the way to go anyways. My question is what is your process for determining ARV on multi-family Properties?
