What I have found that works for these buyers that make offers and then don't pay is.....instead of hitting the accept offer , send them a message and tell them you will accept their offer or even make them a counter offer through a message. If they agree and they say they can pay right way, tell them you're going to change the price of the listing to the agreed price and make it a buy it now. If they don't pay in a timely manner, just change the listing back to the original price with the best offer option. This has worked for me many times. I usually ask if they're prepared to pay right away and tell them i'm going to make the change immediately to the price. I know this doesn't answer your question about withdrawing the offer, but hopefully it helps some sellers in the future
