Here's how I got there:$6800 GSR -$1700 Owner's unit (you'll be living in one unit)-$2890 Expenses (42.5% of GSR - left out CapEx, included management)-$2863 Debt Service ($582k @ 4.25% for 30yrs - that's 3% down on $600k)Total $653 cost to you each monthOnce you move out, you'll see ~$1050/month CF, which isn't bad.
