Now I don't take everything there as gospel but you need to be careful on how you describe media sources unless your willing to take your colored glasses off. 

They have color televisions. 

The house seems to show well but your pictures are dark and they don't pop with color. 

Same colors throughout the house?

We like happy colors in Arizona 

What paint color and finishes are you all using for interiors? 

If you can make it look inviting, not cluttered and use color without it being distracting, a little furniture, not too much, it gives buyers a perspective on whether their things will fit.

I would imagine most of us don’t use the word “colored” or “negro” anymore….. we don’t call a motorcycle a bike or a car a buggy.

What "Goodies" were in it.Apparently you survived the encounter--you might not have with everyone.Maybe your potential renters are seeing something in/about these men that you are missing.Maybe it's as simple as a gang hand sign, or a gang method of dress, hairstyle or color of clothing.Maybe it's some particular 'Body Language" of the "Street" that you are totally unaware of.Maybe it's the pronunciation of a certain word that clues them in.People from the area also may know one or more of these men and know their past history and present "Activities" but not say anything to you about it.Some of these areas in Los Angeles are extremely well kept up--but still have bars over the windows--for a reason.Good Luck!

What I would do to soften the look a bit would be to add colorful, woodsy decor.
