How close to a war zone is TOO close??

[Paul Willis]

Hey everyone!
I thought this might be an interesting discussion, and I wanted to see your thoughts.
The context: I am currently evaluating an out-of-state duplex in Richmond, VA which is in a C class neighborhood with upside. There are nice restaurants 10 minutes away by foot, and a developing scene. One could make an argument that the neighborhood is posed for appreciation. However, if one walks 15 minutes the other way (about 0.5 miles), they would arrive in a war-zone, a public housing project where there are murders reported almost every year.
Would you be interested in this property for the upside potential, or is it too close to the war zone? Another way of asking this would be: how close to a war zone is TOO close?
Appreciate any opinions on this, thanks so much!
