For example, I asked if someone who is unlicensed could show my property.

I would NOT do business with EMRICH Pro, they are expensive, cut corners and their owner spent some time in prison for defrauding a couple million in receipts to the city.Howard Depp is un licensed and is a drunk but poses as a licensed contractor. 

Some investors my allow unlicensed workers to do the work and the Master sign off to get things done cheaper, but I wouldn't feel comfortable with that.

Sounds more respectable than unlicensed broker.

@Jacob Beg This is one of the hazards of dealing with wholesalers, who in reality are just unlicensed real estate brokers operating illegally.Wholesalers in almost every case have bamboozled the property owner into thinking that THEY are going to buy the property (they're not). 

Just save yourself a hassle and make sure to work with only licensed and insured professionals - the accountability helps since there are a slew of virtual unlicensed wholesalers out there that moonlight as real estate investment consultants... it can get a bit precarious once you go down that route.

Anytime you hear the nightmare stories of the fly by night companies that steal the investors money they are almost always non regulated & unlicensed individuals.After that I would make sure you compare a couple and don't just go for the cheapest option.

I have a property where I am considering using experienced unlicensed painters (they work for a painting contractor but also do side jobs).

Maybe he plans to call you an unlicensed contractor at the end - not pay you a dime and report you to the contractor board?

You will be responsible for any code violations that are discovered after the licensing or certification board comes to inspect the property, unless they are planning on running an illegal, unlicensed or uncertified day care.
