What's your pitch to someone when you are a new wholesaler and have no buyers to assign to?

Yes, I can fund their EMD, but I also offer to help them find buyers.

You'd need to put time and effort into finding a buyer, negotiating the deal, putting it together, and keeping it together. 

Earnest money deposits are often required to secure a purchase agreement, signaling a buyer's serious intent to sellers.

Or is it enough to give the buyer/vendee multiple notices, terminating with, "If the defect is not cured by XXXX date, the contract will be considered terminated"?

As an agent if I had an good off market deal I would take it to an end buyer not a wholesaler. 

Lease-to-Own: Could attract buyers who can’t buy outright now but want to.

My partner was on the acquisitions side of things, so he is extremely knowledgable in novations and creative ways to get the property under contract and I still have an extensive list of buyers, I have built very good relationships with from when I was doing dispositions.I am open to any thoughts on the best way to start and I am open to networking with any one to hear how you got started and what you would do differently now that you have more experience under your belt!

The price of the option, paid for by the potential purchaser of the property, is agreed upon and set and is non-refundable.Some sellers MIGHT credit the cost of the option back to the buyer of the property upon closing, but any details of the option may NOT refer to any lease.Why? 

Reverse flipping is basically you find a buyer and then you find a property for them.
