“Broker” is a legal term that often requires standardized coursework and a state license. 

Quote from @Adam Macias: Wholesaling as it is today will be a thing of the past.It’ll truly be strange to even hear people and gurus trying to make big money off it.The more people try wholesaling but then end up not having an end buyer or cancelling contracts or trying weird things like novations, the more all of real estate will be regulated and cause requirements like licensing to be able to transact more than just your personal resident purchase.Which I don't know why hasn't happened sooner.Here's all the states (in red or yellow) requiring a license to wholesale or at least have started the process:Credit: REITipsterI think licensing and regulation is a beautiful thing that should happen if you plan to be an wholesaler and do more than one deal... which is going to be the case for anyone taking this business seriously.Or even it being regulated to need a real estate agent to do more than one deal outside of buying a personal residence.I've had plenty of failed attempts with agents in pursuit of wholesale deals and I know exactly why, it's not because the agent couldn't find me deals, it's just not practical to think there's opportunity for the numbers a wholesaler needs to make a profit on top of everyone else needing to these days.Because the only sellers who truly can sell at a deep enough discount are usually those who ran out of time and just didn't do something sooner with their situation.I know many coaches and gurus will disagree with me but there’s no regulations on youtube gurus and what they teach either.If we look at the current state of the market in hot cities, the availability of online resources to the average homeowner, how many deals can you possibly believe are available at 70% of ARV?

Rent control measures, burdensome employment regulations, and excessive administrative requirements exemplify this.

I know lots of installers don't do it, and I personally prefer the unimpeded look, but anything installed outside of the requirements of the material is probably going to be limited, i.e. the insurance company is not going to pay you because the material was not installed according to flooring requirements. 

Its a great idea, but you will need to consult the township in order to understand their requirements for liveable space.

What special purpose equipment do you have for an ADU/Office that required unique wiring for it to function? 

Lenders can have different loan options based on the property type and the amount of rehab (if any) required for the project. 

(larger would require fire sprinklers). 

As Jonathan mentioned it can be done, but they may require an appraisal of the property. 

These are all important considerations, and understanding the requirements can save a lot of headaches down the road.
