^And assuming one or both parties don’t bank with a popular national bank chain I assume?
(Hand raised) pick me! Easy answer.
USE YOUR BANKS. Done this more than once. You each share banking contacts and buyer approves a wire to the sellers account. And the seller verifies receipt of funds from their banker before handing over the keys.
Piece of cake. Just requires both parties to not be idgits.
And never lived in a state where the dmv had anything to do with the actual transaction. That’s the buyers problem after the sale. And why the buyer gets a signed title and bill of sale.
In the case of a lien on the title, refer to the previous answer. Use the banks.
