Milwaukee Duplex located 4th and locust

[Danny Stern]

talked to a family friend about a potential duplex purchase from them.  its 3bdr 1 bath each rented at 600 each. fully occupied currently $1200. he wants 45K for the property. I would not want to go more than 40k.  he rehabbed it about 2 years ago.  I would put 25% down.  I know this is a bad area in Milwaukee and this would be my first investment. after everything using the 50% rule I would be around $400 a month cash flow. I want to know basically more about what people think about the area. its located right by a police station.
