Duplex Purchase - should I?

[Gardi A.]

hello all i need some advice from the professionals here. i have a deal asking price is 129k BUT i don't have the down deposit and the closing cost funds. I have someone willing to lend me the closing and down deposit repayment terms 5 years. 

now when i run my numbers the property cash flows $544 monthly that 544 would go to the person lending me the money meaning first 5 years i would have 0 cashflow. is this a smart move or dangerous. i see it as since everything is fairly new and my current property manager manages this property as well i would add another duplex to my portfolio with 0 cost to me
