First Deal, am i being to optimistic?

[Lacy Tilley]

First deal working on negotiation.  This deal would be a duplex side by sides. rents are currently low, very low. My plan would be to go in and raise rents close to market units are in decent shape just need minor updating 5k max each unit. My concern is where i would go in.  It is  bad idea to go in with little cash flow per unit? 

These are my numbers going in each unit 525 (seeing rent in area go for 730)

Any input would be great! (Properties would definitely apprises for 100K) 

I have done one live in Flip which worked out very nicely, would be using profits to fund this deal

Would you do this deal?
