Loitering around property...What can be done?

[Tiffany S.]

How do you all deal with loitering? There is a foreclosed home for sale next door to my rental property (Houses are very close). Every once in a while I ride by and see people standing around on the sidewalk, sitting on cars, etc. I also see people enter/exit the shed of the foreclosed home. (not the same people I see standing around). I suspect they will run off potential renters as there are many of them at times, and they can get pretty loud. The neighborhood is a D+/C- I would say. I never see people on the surrounding streets. Just this particular block.

Has anyone ever dealt with this before? It's not on my property but right next to it ( to the point that it made it difficult to get out of my driveway because there was a car with about 10 people surrounding it.
