Then you get the tenant's credit check, criminal, eviction reports.  

@Craig HormesI have had several Section 8 tenants over the years and have learned a few things.My properties are always really nice so I expect them to be taken care of.I always pull a background check, including criminal and evictions and call all references, just as I would with any tenant.

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.
