So I typically decide to work with them to come to a win-win situation for both. 

Carson demanded I send in money WITHOUT providing a PSA (Purchase Sales Agreement), then refused to supply a blank AOM (Assignment of Mortgage) or Allonge for the 2 crappy notes I did end up winning the bid on.

Negotiate with her for a win-win.

Tortious interference would only possibly apply if you got them to cancel/default on their contract, and even if you did, you'd probably win in court, assuming a wholesaler would take it that far, as in Ohio and Fl most of these wholesaler transactions would be violating state licensing laws anyway.  

The small win that I achieved was being able to successfully trace an owner of a property from a post card that was sent back to me as "return to sender".

A good Realtor will work with you on preparing an offer that will win the sellers over.

Lets assume you win in small claims court and they pay court fees.

If there's anything that would back up my point is Dale Carnegie's book "How to win friends and influence people." 

I want nothing to do with leaky faucets while Mickelson is on the 18th hole at the US Open on Fathers Day with a chance to finally win!  

Heads you win big, tails you lose small, but the house always wins, and you're the house.
