There is at least one escrow company that would do it. My son used them with a sticky situation buying a jet ski for $12,000. The sticky part was the son co-owned the jetski with his dad whose name was on the title and there was a lien. The dad was in on the deal, wasn't shady or anything and the dad and son both cooperated. So my son used an on-line escrow service to handle it. No money was delivered until the title was released and transferred cleanly, then the money was paid. When I bought my new moho from a private individual, he suggested I look into it. I did and they would have handled the transaction, which was over $100,000. But in the end, my investment account wired the money to the seller's bank. They owned it free and clear with a good title, so that worked best.
