How do you Manage in bad neighborhoods?

[Samuel Liapis]

I am looking to buy a second multifamily in Chicago, I have been searching far and wide and it seems that I can only afford the higher crime areas of the city. Have you invested in these areas? If so how do you manage them? Do you use a management company? Do you self manage and go there to collect rents?

I need some help to decide how I want to expand my areas. If I see a good deal in a high crime area, how I would go about managing it.

Thanks in advance!
