Value is key
As a REALTOR, I can tell you that the similarities to buying a boat or house are virtually identical. I offered initially, 35% below asking and settled on 24% below asking. I knew the recent comparable sales prices. Asking price has little to do with actual value. Some people seem to want to win the lotto on sales prices of their property, boat or home. All you need is the knowledge of actual sales price that can support the offered price. For example if you made an offer of 70k on a boat that has a true value of 130k, that would be insulting. How could you support it if virtually identical boats in model and condition sold within the last 60 days for 130k? As someone else replied, if you offer close to actual value, it won't be an insult and you would likely get a counter offer or acceptance. Brokers have the information on recent sales that can support your offer. You must have an appraisal/ survey to get insurance, and want to make sure in the offer that the offer is contingent upon the survey at offered value or more. Remember, a contingency can be removed only by the party that is bennefited by the contingency. Don't make it subject to. I've come across brokers both good and bad. Check with others about the reputation of the one you choose. Ask for past clients feedback.
