I am a real estate investor (with a concentration in buy-and-hold properties) as well as a Police Officer for the city and I will warn you that crime is an issue.

My septic inspector regularly tells me there’s generally no septic police for these matters once the property is built.

They don't police these.Now, that being said, consult with an attorney in the state you're looking. 

They should call you instead of calling police or Airbnb. 

If the tenants are truly that loud, the other tenant could call the police for disturbing the peace if they wanted to.  

Yes, this theft is recorded with the police.

Police were called a hundred times, management was notified, nothing was done.

It is very very rare for a DSCR Loan to have a prepayment penalty duration more than 5 years2) Generally this will range from 5% for the entire period, to a "descending penalty" structure which is very common - such as "5/4/3/2/1" where its 5% first year, 4% second year, 3% third year etc. 

Police and fire all live out West (Piper) because it's nice there, and homes are $300k+.

Police would do nothing.
