I was tracking your boat on FB Marketplace when it was first posted. Ironically I was selling a Lightning at the same time.
Reading some online conversations about the boat, the main issue for potential buyers is the condition of the hull. Given that the hull is cored, repairing damage can be very expensive. Also, people think that water intrusion into the deck spreads well beyond the water intrusion area. This means potentially thousands of dollars of repairs.
I know that it is hard to spend money on a survey for a boat that you are trying to sell for $1000. But it might be worth the effort to get a survey on just the hull, deck, and bulkhead. This would establish some boundaries on what the new owner of the boat can expect to pay to make sure the hull, deck, and bulkhead are sound.
Hopefully you can find someone willing to take on this project. It looks doable to me, with boats in good condition selling for $15-$20k.
