Wholesalers. I don't understand their mindset

[Mark Spritz]

So here is my dilemma. I think for me in my investing, either going the Multi-Family Rentals or Flipping or BRRR, still trying to decide. But I think in all cases using a Wholesaler might be a great idea, but I can't get over the fact that if they have these great properties.

Why aren't they doing it themselves? 

I mean if you find a property that you get under contract for 100K, and you estimate Repairs at 25K, and that you can then sell it at 200K, why wouldn't the wholesaler do that all themselves? And regarding the property itself, if that was truly that great of a deal, wouldn't the seller also know it, or the seller get a realtor to tell them that, or a retail buyer see the listing and know that. It is just so confusing to me that there can be such deals. I am kind of at the, "sounds too good to be true" stage.

Thanks
