List and corresponding sale transaction information
Have recently begun the process of looking for a used boat. Between the reading I've been doing (Vigor, Calder, Roth, and others) identified a boat in Europe I decided to get more information on. Contacted broker, asked for, and he sent, information on transactions of used boats involving that model over the past ten years: production year; list date and price; sale date and price. With that I estimated the average ratio between the list and sale prices (0.92, sale over list). Please note these caveats: I have no way of verifying that the data provided to me are accurate; these boats for which the data were provided are expensive (average list price of 268,000 USD; average sale price of 246,000 USD) so that the results may not apply to boats in other price categories; the ratio between the list and sale price (sale over list) on the 48 boat sample was from 0.67 to 1.10 (one boat sold for more than listed. Not sure how to interpret that, but list to sale date time lag on that boat was two years. For every other boat in the sample, the sale price was below the listed price); the data cover the ten year period from 2001 to 2010, and market conditions, currency exchange effects, and ?, will certainly have affected the data over that time frame.
What do I conclude? The data imply an average differential, on boats of this type, between list and sale price of approximately 10 percent. The more important conclusion is that there are data, available from brokers, which can help a prospective buyer get a sense of the current market differential between list and sale price. That is, do not consider my result, on this sample for a particular boat type, a reliable rule for use in determining an offer, but rather an exercise in trying to extract market information from historical market pricing, which other prospective buyers can also do.
