I don't know the details and legality of doing this....Let's assume you want to sell the plane for $100K. How about having a raffle and selling 100 tickets at $1000 each (only the serious shoppers will bite) or 200 tickets at $500 (some half-serious shoppers will bite). Maybe have a non-profit aviation organization (like a large EAA Chapter) run it with $10K from the proceed goes to them for their effort; you probably can write-off that $10K. Just a wild idea from drinking too much coffee.
