I still haven't mastered the advanced quote reply so here..
"When wholesaling, I separate myself from the seller (FSBO) and recommend they use a listing agent. If they choose not to, then I have them sign an acknowledgement stating I otherwise STRONGLY encouraged them to do so. "
From this -- I'm assuming you a licensed? If not, why do you choose to do this? You're there to help the seller and make a profit yourself. Why give them other alternatives, barring you are not licensed?
There are many investors with licenses. It's common. You rep yourself in the buy, and pay half commish when you sell. It's a smart idea.
Sure there are endless scenarios that COULD play out, that's life. I don't necessarily feel we need to expand on the negatives, when the positives are much stronger. You can pick at anything and turn it into a negative.
But like you said, all it takes is one time, so you have be ready for it, and accountable at all times. And when you're in RE school, you're brainwashed that over and over.
Your last line says it best. "Better safe, than sorry."
You better have your ducks in a row if you want to carry a license and flip for a profit! And most of us do, we aren't all that bad! :)
