We are in a time of great financial chaos. It means you need a cash buyer. There are not a lot of them right now. It might be the worst market since they invented recreational boats. There is no credit any place on the planet right now.
You can sell it quickly at the right price
or take longer and get more. Hiring more brokers eventually might get you there but at least you will then be buying
in the same buyers market. Trading down just might work if you can avoid firing every broker you hire. It takes the right buyer and that takes time. It's not like a broker can make someone buy your boat. If they really could do that then it would be a sellers market.
Everyone selling knows why their broker can't sell their boat, but they never come up with cash or a buyer to pay for it. The answer is simple - lower the price
or wait. After you fire a few more brokers you may be in a better mood to lower the price or wait. That is all the options sellers have.
