One of which is Transunion's Smartmove, which offers credit/background/criminal type checks.

If so, I’d pay a lawyer $150 to write a strongly worded letter to them, accusing them of slander, pointing out that it’s a crime, and requesting certain actions (such as that they ask VRBO to take down the review or they will face criminal charges).2) I would also write a comment below their review pointing out the truth - keep it brief & keep it professionalGood luck!

Will they provide criminal background checks of their principals? 

@Dashiel C Neimark Washington State is tenant friendly in general, but most of the more onerous regulations you hear of (RRIO registration, no criminal background checks involved, first-come-first-served rental applications) are Seattle city regulations.

Heck, I even heard a guy on the podcast talk about filtering by criminal records, haha.If there's any kind of inspector-client confidentiality rule or law, perhaps you could just ask him about that before moving forward.

Because by doing this the applicant was able to pay the $29 and you got the credit report, back ground check and criminal history check.

Criminal activity is not a protected class and actual values and opinion of values and their trajectory is just data, right?

Be mindful of the criminal activity in specific areas.

As we all know criminal cases take a ton of time.

Of course, if you became aware of your tenants using the electrical or the telephony services to carry out criminal acts, the situation would change similarly.
