I would do a certified check, I bought some land off of a co-worker and we both went to my credit union and they just cut the check out of my savings account and made it out to him. He went to his credit union and deposited it and it was good to go. Maybe give your bank/credit union a call and see what they recommend.
Also that is where we got the notory to sign and do some of that stuff too. But different situation.
