In my experience, wholesaling seems to be a pretty cut and dry business where you market to a seller, meet a seller, put a house under contract, transfer that contract to an investor who wants to either flip or rent the property and collect an acquisition fee for your hard work marketing and acquiring the property.There's some wholesalers out there that do some practices unethically but dont let that wear on your ability to act with integrity and do whats right by your seller even if your not the best solution for them at the end of the day.  

I have a game plan, checklist of things to prepare before DM, and scripts to practice for talking to sellers and listening for distress and motivation if you want, just hit me up.That is a rough rule of thumb that is as helpful as the 2% rule lol - very debatable.
