Wholeselling Seller Representation

[Ikenna Okoye]

I wanted to get some input and clarification on some wholeselling practices. I was talking to a potential off market seller, who happened to be a RE broker, and he brought to my attention illegal activity in wholselling in the Houston area and that wholesellers where being arrested. im not sure if he was just full of it and trying to scare me, but I figured I would check anyway. He informed me that I,

1. needed sellers written permission to market a wholesale deal

2. Needed to represent the seller through the process

I cant find anything specific, but could anyone verify or dispel whether these things need to be done. If so, maybe point me to what i would need to do to go through a legit transaction.
