In the duplexes we give one of the tenants a $50/month reduction in rent to cut grass, shovel snow and police the common areas.

I am also contacting the police and local animal control and seeing what can be done to get the animal put down. 

Get the police report.

if you start calling police.

Neighbors call the police. 

You can call the police department to see if the property owner has been the victim of a homicide and therefore the property will not be able to get clear title.

I am a single dad and will be an owner occupant, so my daughter and I only need a 2 bedroom, from day one the seller agreed to evict the tenant from the 2 bedroom unit as part of the deal, as this tenant had already been violating the lease by subletting to heroin addicts, multiple domestic violence police calls, late rent payments etc, and the other two tenants have been there for a very long time one for 12 years and the other for 20 years.

You might call me a slumlord, but the police certainly don't.

Many stores now run cash through counterfeit detection machines and call the police when they find any.Many stock brokerages stopped taking or giving cash in the 1980s when Congress passed the "know thy customer" laws to crack down on money laundering.

I got tired of being picked up by the police.
