How to stop people from hanging out on your property

[Eric Var]

Hi all, I own a 4-plex in an area where people like to always hang out in the street and for some reason some of them always hang out in the front of my property even though they don't know anyone that lives there. They just sit out in the front every evening. Has any of you been successful in getting them move along? It's not a good look when Im trying to show the unit to new tenants.
