Man, I'm here to tell ya, as soon as you take out the slide rule and calculator, you've lost.
Thre are FAR TOO MANY variables that go into a boats asking price to use any type of percentage figure.
Typically, a broker will try to get the owner of a boat to list at "fair market" value. This works less than half the time because owners (me being one) want the biggest return on their investment that they can get, I don't fault them at all.
The problem rears its ugly head when broker "A" says "Joe, your frogbobber41 is worth 42,500.00. I think thats a fair price."
Joe, being of sound mind (ok, he's a boater, I realize thats an oxymoron) sez, "Lemme think about it" and heads over to Broker "B" who says, "Joe, you gots one bee-uu-teeful Frogbobber41, I think its worth 69,989.99"
Joe, feeling rather taken aback, says to broker "B", ok, list it.
Broker lists it exclusively for the 6 month contract term, or longer.
Joe ain't too pleased when not many people show up to look at his boat.
Who's at fault? See what I mean?
If broker "A" had listed it, the boat would most likely have been sold at very close to the 42k.
if broker "B" accepts offers at 42k, thats better than a 30% discount.
It happens all the time.
The "free" end of BUC is almost worthless, The paid for section has much better data. (and the chicket from BoatUS? she calls brokers and surveyors)
We are not primarily on earth to see through one another, but to see one another through
Some people are like slinkies: not really good for anything... but you can't help laughing when you push them down the stairs
