Ethics of Wholesaling

[Reilly Brown]

I recently came across an interesting youtube video laying out an strategy for wholesaling, where the wholesaler basically low-balls as many properties as possible, hoping to find just one or two highly motivated sellers who bite or at least counter close to the low ball offer.  The offer is formed by taking half of the zillow estimate.  If there is a listing agent already involved, you try to get their help by offering for them to double-dip on the commission.

My question for this community is if its frowned upon, or considered very obnoxious to take such a bulk approach to finding deals?  On one hand, I see how this can be an effective way to weed out unmotivated sellers, especially for rookie wholesalers like myself.  On the other hand, I imagine this could be a way to make a not-so-great name for yourself.

Also, is the double-dipping for listing agents considered a dodgy practice?  Given that you hire an agent with the expectation that they will protect your interests, how can we expect them to do so if they are representing both parties in the deal?
