Let's say you're interested in a sailboat and to put some ranges on the numbers let's say27'-40', $40k-100k, cruiser/racer, racer/cruiser, 5-25yrs old, nothing extravagent but not a project boat (at least on first glance).Ok, now let's say that you offer something less than the asking price, say 5-10% less, and get an acceptance contingent on survey.Now to the question, what is normal/customary (I know, many variations, no real normal) use of the survey results with respect to accepting a boat1) Every boat has some defects, the survey will show these but shouldn't be used to further adjust the price. The agreed price is with the understanding that the survey will find some problems not already obvious to the casual buyer.OR 2) Every boat has defects, the survey will show these and it is expected that the agreed priced will be negotiated down further after the survey.OR3) The survey results should only cause a price renegotiation if major structural/safety issues are discovered that could not be found by casual inspection, for instance if the boat was inspected on the hard by launched for survey.OR4) ??By casual buyer I mean anything beyond raw newbie but well short of professional surveyor with years of experience. I know that every boat is different, every deal is different. I was just wondering what people here think is the best practice when going through the purchase process.
