I requested them file a police report, and I would look into my options.  

And some neighborhood groups organize volunteers to remove them.And the police can track you down and issue a ticket, but I don't know how zealous they are about that.

Downtown and Midtown are definitely improved, but there are neighborhoods that need police, fire, and lights.

I considered the vultures descending but felt accurate answers to my question were more important.

You can probably expect more drinking, drugging and fighting also, and accompanying police calls and damage.

I sent them a letter saying that the police department had informed me that my property was under surveillance for suspicious activities.They were out within the week.:)

With 1-4 units I talk to neighbors, get rent estimates from my property manager, check for police reports.

I am surprised the non-recourse loan police haven't jumped all over that comment Rob!

Tenant, and surrounding neighbors report seeing a blue flame glow from a butane torch outside the window, pellet gun, and even him cutting a hole into the screen.After an incident of opening his blinds and having what appeared to my tenant as a pellet gun pointed at him through his window by the neighbor, the tenant called the police.

You might have to deal with the police if the renters are throwing a loud party or someone overdoses in the house.
