Lookey-Loo's can get all basic questions answered, and you can include the disclaimer that "applicants must submit to credit application and criminal background check" to weed out any low-quality renters and keep them from wasting their time (AND YOURS!)

Druggies and criminals don't like to be watched.

You made it sound like people who are doing STR are criminals. 

Criminal background check.  

I have been trying to warn others that what they teach will get you in trouble, either civilly, regulatory or criminally.

@David Dachtera Jeff BeardEven if you have a complicated business entity, if you are found to have been intentionally negligent or involved in some kind of criminal activity, you will still risk being personally liable, right?

If  you want to be a cop don't get a criminal justice degree because being a police officer requires 4 year degree in any major (in my area ate last).  

None of that even begins to start addressing plumbing issues, structural issues, covered up defects, defects created by the flipper and a thousand other things anybody in the construction business continually uncovers on a daily basis dealing with homeowners when that homeowner calls in a professional to do some renovations and exposes all the criminal activity that flippers do in the name of their profits.Now I hate to generalize, and their may be exceptions in other parts of the country, but I have 10 years of personal experience witnessing this over and over again here in Denver.

That is why accountants are selected very carefully on a business, just like selecting an attorney for a criminal defense, if selected wrongly, it will cost you to correct it.

I don't blame you for not wanting a criminal in your property.
