Is this a deal?

[TJ Woolum]

Hello,

I am new to the multifamily arena and need help analyzing this deal.  Any thoughts?

Quadraplex

3 units recently renovated and rented at $1,200/mo

1 unit unrenovated and rented at $750/mo

NOI: $35,000

Listed Price:  $449,000

15% down on a 5 year balloon, amortized over 30 years:  $2,475/mo

With these numbers, I project the monthly cashflow to be $173/mo.  And that is if I manage the property myself.  What do you guys think my asking price should be?  How do you evaluate your deals?
