I have decided just to go to his bank where they said they would cash the cashier's check on site. I can deposit the money then and there, sign off the paperwork, and be done that way. The buyer said he would be happy to do that and even asked if I had a ride home (which I do). Seems like a very nice guy. Will report how things went down tomorrow afternoon.
Thanks again for all the advice.
