I'd love to learn how to do analysis on small multifamily properties that are owner occupied.  If you yourself are living in one unit,  I would think these "base hit" numbers,  12% CoCroi, $100/ unit rules of thumb would change, but how? With the rental calculator is there a way to compensate for your occupancy as owner?  I'd love to figure out a formula that better incorporates this owner occupied value.  Thoughts? Ideas? 

Evaluate it as if all units were not owner occupied then work backwards.  If it doesn't work when all units are tenant occupied it is likely not a great investment.

Thank you. Aaron K. That's a different way of looking at it.  Appreciate your response. 

If you are looking at this as an investment then listen to @Aaron K. 's comment. However if this is to be your home long run then consider that it is a way of making your housing expense less expensive.
