Some obvious advantages would be access to the MLS and not having to pay someone else fees for listing a property (if you were to). Or what if you simple ARE and agent, and want to wholesale as well?
Regardless of all that, however, we're ultimately not taking a listing contract or representing a buyer as an agent, essentially eliminating fiduciary duties.
Moreover, you have it all backwards. Disclosing that you have a license is not to make you seem more legitimate or so that "the Seller is ENCOURAGED TO BELIEVE that their interests will be looked after"; on the contrary, disclosing can negative for the wholesaler since the seller might become distrusting of them since they are seen to have more real estate knowledge.
As long as you disclose that you are licensed, are not working for them, and they understand you are buying at a discount for business reasons, there is no slippery slope.
However, always keep in mind that working ethically and morally should always supersede any legal obligations! But when it comes to wholesaling with a license, there is no issue as long as you go about it properly.
Good discussion, appreciate the dialogue!
