Cashflow vs. Cash on Cash Return

[Chris Wenchell]

I have been using the rental calculator for a few weeks now, and I know it's best to have at least a $200/unit cashflow on 2-3-4plexes, with at least a 12% return on investment...but when I changed the down payment from 20% to 3.5% my cash flow went down to just above $500 and my return went way up to above 34%. Would this be considered a good deal?
