He finally contacted me and asked for a payment extension, and I told him no, that I had already given him a great price and plenty of time, but he ghosted me. I offered him the option to pay in full today or I would put it up for sale. He was actually very nice about it and said that he was sorry and he didn’t have a problem with me selling it. I told him that he’s a nice guy and I like him, but that I was stressed out because I thought he might be dead or in jail and that all of this could have been avoided with one simple call or text… Many thanks to everyone who offered me great advice in my first post. I will ALWAYS get a 50% deposit and have a written agreement that includes expected time frame of payment, storage fees after a certain amount of time, and what happens if I’m not paid in a timely manner… I’m good at working on old shotguns. I’m not a very good businessman.
