@Brett Elia I'm a little late to the party, but I skimmed through and think I have a good idea of whats been said and what hasn't.
Wholesaling the MLS is not about tying up some property at list or slightly below and trying to off-load it to someone else (although it happens often).
Wholesaling the MLS is very similar to sending postcards, you send 1000 postcards to owners and hope a motivated seller that needs to get out of their house responds. Wholesaling MLS you send out 30-60 offers a week and hope that 2 find motivated sellers that need to sell their house that maybe their realtor has fallen asleep on and hasn't lowered their price.
Buying investments off MLS in a competitive market is about finding the soft spot in the market, the houses that are willing to take much less than the list price, the only way to find that is to make a ton of offers.
I've never "Wholesaled" anything on MLS, I've made a ton of offers and connected on some directly for investors or bought it myself. As a realtor, negotiate a full priced back end listing in exchange for writing all of those offers, and it should start to make sense.
