I'd send a link but the BP police keep knocking me down when I do that :-)

Call your lawyer first, but you should probably go straight to the police.

Do your homework on the specific areas, check the school districts, check to see crime, call the local police or building department and ask about that specific street (they shouldn't tell you anything but sometimes they do!). 

In the case of a bin being out front early, unless there is a police report showing someone broke into their unit and removed the bin I think you're claim would be well founded.

The tenants also ignore my letters, emails, phone calls and texts when I try to reach out to them. in one occasion I went to do a home inspection and they refused to give me access to the property and even threatened me to the point where I had to call the police. 

You should also have a posted notice about quiet hours and instruct renters to try and work it out with the neighbor or report noise complaints to the police.

I'm currently a police officer here in Houston, however my goal is to become a FULL TIME INVESTOR in real estate.

In addition to that, we like to check with the police, fire, insurance, sex offender status, and anything that might affect the operations of the park.

Some custodians do have internal polices that where they choose not to process certain transactions that can lead to greater complexity in account management such as foreign real estate or UBIT creating trade or business activities, but that is a business model decision, not a legal restriction they are confined by.This lack of oversight is a factor of the regulatory environment, not their service attitude, by the way. 

You could also try the local coroner’s office or non-emergency police number to see if any deaths were reported?
