Should I also assume that if a listing over 6 months is still active it is priced too high?
I think it's too broad a statement - if one drops the price low enough, any reasonably maintained boat will be bought. So we could extend the statement to say that any boat on the market longer than a week is priced too high. On the other hand, it could just mean that the right buyer hasn't found it yet for a variety of reasons not related to price. If a house is on the market for more than 6 months, is it priced too high? Not necessarily and there are a lot more home buyers than sailboat buyers.
As with home values, recent
comp sales are the most reliable judge of current
