Sounds ridiculous I know, but the Pinellas County Contractor Licensing Board has full time people driving around looking for unlicensed handymen doing work such as what I mentioned above.

That someone would be working with an unlicensed agent?

How about "unlicensed real estate transaction coordinator" ?

The problem is folks have no intent on closing the deals they tie up in contract...so it equates to unlicensed activity...advertising is another issue...99% of wholesalers here are not doing this correctly, but some are.

I have to dig on this as I know certain states do not allow a brokerage to pay referral fees to unlicensed individuals (might be different in a deal happening solely between investors).

., there are probably many unlicensed people who manage other people’s properties in RI every day of the week.

Recently I learned from multiple neighbors in the community that the police got involved many times because this tenant plays loud music at nights and rides his unlicensed motorcycle up and down the road.

Arbitrage is basically managing an Airbnb at the end of the day, although if you're unlicensed it's wise to be careful about not handling money, leasing paperwork, accounting, negotiating rent amounts, or crossing over into what could be considered regulated activity requiring a license (in most states). 

Sometimes cheap labor could be costlier on the long run, i.e. vacant unit for longer time frames, accidents, liability for hiring unlicensed contractor.

For example, under most circumstances, if an individual is involved in unlicensed activity for one month, a civil penalty of $30,000 may be issued.You may ask, “I’m a licensed real estate broker (or salesperson), why are you telling me this?”
