And from the seller's point of view:
Don't come back with a counter offer 25% lower than asking because it needs x, y and z. I know this, that's why I set the price where it was when put up for sale. Start with the price of a new boat and deduct the value if you think fixing x, y and z should be on my tab or you want them corrected as a condition of sale to make a 25 year old boat like new.
But yes - these flaws should all be mentioned if known. Inventory and age of sales, structural integrity, maintenance history, rotted cores, etc.
And this is where I have a problem. Owners getting bent out of shape by what they perceive as a low ball offer.
This is a negotiation. In negotiation the seller starts high and the buyer starts low. it's the opening bid. That's the way the world works! Nothing to get the short and curlies twisted in a knot over. Buyers can't go down price once they've put an offer out there. The offer can go only one way - up.
As you, the seller, has judged what the boat is worth, I the buyer will make that same judgement. And since it's my money making the deal go to closing, my judgement will prevail. That is - we need to agree. And either we will or we won't.
Regardless, the worst thing a seller can do in a negotiation is get PO'd at a buyer over the opening offer. Geez, got an offer? Any offer? let the game begin!!!!
