I took a deposit on a motorcycle I have for sale, I also signed a contract stating the balance would be paid when I delivered thr bike to the owners residence. We had a verbal agreement to deliver the motorcycle the following Monday or Tuesday when the buyer got back in town. The buyer is one pushing the date back by a week, I am concerned that he doesn't have the rest of the money. There is a 21 day clause written in the sales agreement. I have a back up offer on the motorcycle, can I legally give the first buyer 48 hours to perform on the contract or return his deposit and sell the motorcycle to the other guy?
