Our approach has generally been to focus on driving demand rather than pushing supply. Most brokers don't have the combination of registrar, landers, financing and brokerage all under one roof. As a result, we can create value in more ways and generate more organic demand which in turns that the buyer is buying rather than the seller is selling. This makes all the difference especially when selling in 6 figures and higher.
My many external domain listed buy now price, (Also used epik nameserver).
I think better option only make offer listing, if any deals done... Use escrow service or first transfer domain epik account then accept offer etc....
