I just read an awsome little article in the local nieghboorhood news letter. An Apartment owner bought him self a 30 unit apartment complex and they day he show up to it for the first time the cops are crawling all over it arresting a guy. So he investigates and finds out this is normal there. The seller didn't bother to disclose that info to him.
So he moves in for a time, starts harrassing anyone who shows up and he doesn't recognise, ejects some bad tennents, remodels the place and gets in contact with the local police. he then turns an apartment into a local police substation. The cops now have a place to hang out and do paper work, and he gets the added presence.
If you plan to move I'll get the info to you. I drove by the place yesterday. Looks much nicer then it has in the past.
