STRs don't cause shootings, guns and criminals do.

When I set up my first MTR property I started by creating my listing on Furnished Finder then used their affiliate, Keycheck, both to run the background check on prospective guests (it includes criminal background check, credit score and eviction check) as well as their state-specific lease.

—In all criminal cases, contempt cases, and other cases filed pursuant to this chapter, if a party has sold, leased, or let real estate, the title to which was not in the party when it was offered for sale, lease, or letting, or such party has maintained an office bearing signs that real estate is for sale, lease, or rental thereat, or has advertised real estate for sale, lease, or rental, generally, or describing property, the title to which was not in such party at the time, it shall be a presumption that such party was acting or attempting to act as a real estate broker, and the burden of proof shall be upon him or her to show that he or she was not acting or attempting to act as a broker or sales associate.

Up until last year, we were one of the last states in the country with a criminal eviction statute. 

The screening includes credit reporting, employment status, eviction history, and criminal background check. 

I'm a private lender in NH and personally I won't do any deal unless I can walk through the house, verify that I believe the borrower's rehab budget, do a criminal background check, verify that he has the cash reserves to carry him through, verify his past experience of successful flips, etcetera, etcetera.  

It checks identity, criminal background, national eviction and credit summary.

The District Attorney WILL file criminal charges and you WILL go to jail. 

Tenant screening is very important - not just credit checks, but also criminal background checks and even previous landlord references.

If they don't pay and are staying it's a criminal offense, you call the cops, they haul the deadbeat away.But cities obviously don't want these deadbeats roaming the city home less, so that's why even in landlord friendly areas, it takes a month or two from the time they stop paying to get them out of the home, all while the landlord eats the cost of that.But it get ridiculous in these liberal areas.
