Milwaukee Duplex Analysis

[Jesse Curtis]

Hi, First time buyer of a rental property and this is my first run at the numbers for a duplex. 

Property is a 2/2 Duplex (1 bath) with a 2 car garage. Currently occupied. Rents and taxes are actual. Asking price is 145,000.

I know a 100%/mo. per unit cash flow is a common goal I see, is that number calculated before taxes?

Any advice or things that look out of the ordinary would be appreciated.
