For example, I usually buy houses directly from sellers, but last week I started to make some creative owner financing offers for some houses through real estate agents. Once I was able to talk to the agents representing me, they immediately saw the benefits of my offer to some sellers. Unfortunately, the agents I talked to would be presenting my offer to another agent that represented the seller.
Finally, there is no such thing as an oral offer! An oral offer is really just a test by the buyer to see what the seller will or will not accept. Make the buyer put the terms of the offer in writing as an intermediate step toward securing a legitimate offer.
