- to me this was another way of saying "I am going to have some of my undocumented employees living here (yes they disclosed some undocumented individuals, however, the potential leaseholder is documented)Someone please talk some sense into me LOL this is my only official applicant as of now.

Then, if you want to get into flips in the future, you'll be locked and loaded.I find wholesaling a rather dark practice and of questionable ethics, mainly because most wholesalers don't properly disclose what they are in fact, doing. 

A good wholesaler that never runs out of buyers are the one who always disclose everything and do what they say. 

You need to disclose, disclose, disclose all of it and buyers may have an issue with it or use it to negotiate the price down or just offer less, even if their concerns are unfounded.

@Stuart Udis I was wondering if disclosing this to the broker could have adverse effects on the appraisal itself.

In fact, they should be reported to the authorities for what I consider criminal behavior and at minimum for bait and switch practices and failure to properly disclose.

And or I would be talking to a good RE lawyer to understand what liability you might have if you recommend this or don't disclose all the bad things that can happen and your client ends up in a mess. 

Do I have to disclose to buyers that this was a marijuana grow house in the past even though everything has been cleaned up and there is no mold?

There were no pets disclosed in the booking and I was surprised to see them.

Disclose if and how you benefit when others get into this while you're at it.
