Bought an investment property in a mixed neighborhood. One of those that one block is very nice and the next street over is so so.

The house has been vacant for a while and now I am taking over and need to do some rehab. For this reason I am not there on nights and only there a couple of times a week.

I noticed on my driveway cig butts, sometimes broken glass bottles.

In talking to a neighbor he told me people are hanging out on my driveway because they know the property is vacant. They are drinking, making loud noises, sometimes 1 or 2 cars parked there sometimes 3. There were occasionally other cars driving by he thinks they are selling drugs.

He also think the guys (16-18 year olds) are "friends" of a guy across the street. That couple have two sons 16 and 18 year old. One of them been arrested a few times, last year had broken into a few homes on the same street. One time tried to sell drugs on his own lot and his mom called the cops on him and later kicked him out of the house, nevertheless he comes back once in a while and his younger brother is on the same path.

Now they see my property being unattended and started to hang there.

Should I call the cops on them? My neighbor says to do so but to call from a public phone as "anonymous" because they might find out who called in and seek revenge.

Any idea how to deal with this situation?
