Specifically if someone acts a certain way online, I have no choice but to assume they conduct business in person that same way.

Do you expect a wholesaler to conduct a Prelim before presenting it to an end buyer? 

Wholesalers try to skirt laws and usually trash standards of ethical  conduct, it's like a back alley drug deal, under  the radar of regulators......and you want to put it on the internet? 

While this guy is held to a higher standard of conduct, wholesalers can easily fit in the same shoes.

Conduct your business the way banks do.

Also, you stand a better chance of learning the "correct" (legal, ethical, respected) way to conduct your transactions as opposed to questionable guru tactics many (but not all) wholesalers seem to employ.

I'd start with attending anything the National Association of Residential Property Managers is conducting.  

We  actually make our vendors sign a code of conduct form of how they are to operate when dealing with our clients properties.

I review their records and conduct a detailed inspection of the rental prior to renewal.

JayMA is one of 3 or 4 states that pretty much require an attorney to conduct the closing.
