With regard to single family (detached) homes, we do not typically require vehicle info, BUT, if I see an unlicensed vehicle or a wrecked or major project, I might issue a notice of violation to the Tenant, or at least discuss it with them.

Going with an unlicensed and illegal Property Manager would be in my mind pure lunacy.Some in this thread have implied or out right stated that a larger Property Management Company equates to a lower quality product.

Lots of unlicensed PMs running around town.

many reit's here in town own hundreds of rentals and hire unlicensed folks to manage their homes for them as employees.

Sure beats the heck out of the unlicensed brokers and their "subject to partners approval" and other BS escape clauses!

If they are unlicensed, the recommended action would be to sue them in Small Claims Court.

So when a property owner is approached by an unlicensed individual there is the added layer of apprehension and fear of risk involved.
