You know there's a lot of good information in this thread about how it
should be done. But I'll admit to having it done it differently. When I sold my
B2710, the buyer showed up one afternoon, and when I told him I'd have to have cash, he said he'd come back in the morning. Now I didn't ask for a deposit, but he insisted on giving me a $200 deposit to hold the tractor until the next day. I offered to go in the house and make out a receipt but he said that wasn't necessary. So he showed up the next day with the cash. He never asked if the tractor was financed or whether there was a lien on it, so I didn't mention it either. Well, it
was still financed with Kubota Credit. So when he left, I immediately called for the payoff amount, wrote out a check, went to the bank to deposit the cash, and to the post office to mail the payoff.
Yes, he should have asked, and I guess some would say I should have told him without him asking. If I had not immediately paid it off, he and I could have both been in trouble. but actually he (the buyer) was the one running a risk, since I was getting cash and knew I was going to promptly pay off the note. Incidentally, I also offered to make out a bill of sale and he, again, said that wasn't necessary; that he didn't need it.
Certainly not the way I'd recommend things be done if you're the buyer.
