I understand the cash and the zelle transfer are not reversible.
So since he’s paid you, I would assume that he means well, just a poor planner buying an asset he’s not really prepared to receive.
It doesn’t sound like a scam to me since neither payment can bounce.
You can charge him storage. Might be hard to collect. Wouldn’t be surprised if he comes back and wants to reverse the transaction. And then that’s up to you. You might keep part of the payment as a “restocking fee”. But I’d make doubly sure that zelle transaction can’t be reversed before I gave him his money back.
Thanks for your advice, I wondered about that, that he might want to back out. He can’t do anything about the bank transfers but he could be plead for his money back, since he hasn’t taken possession. When he spun out the transmission story I thought about that.
I don’t know if it makes any difference legally, but I’m wary of this going past 30 days. It’s like the house guest who won’t leave.
