Here is a link to FWC
and Florida Boating
Are you going to keep the boat in Florida?
Regardless, basically you want to write an offer contract
that states the purchase
amount and any conditions that will let you out of the contract
or let you re-negotiate the price. Those conditions are typically survey
and sea trial at a minimum. You also want to put a time frame on the offer that is long enough for you to get the survey and sea trial done, but short enough to compel the seller to action. There is also normally a bunch of other legal
stuff designed to protect all parties from giving their money
to scam artists.
The "tricky" part comes next, most brokers/sellers will want a 10% deposit that gets held in an escrow account (notice how the 10% nicely matches up w/the brokers fee). Brokers have these accounts at the ready. Note that in your discussions with the seller, you might not have to provide a deposit.
This probably comes under the heading of bad advice
since it is just an overview - I ain't no lawyer and all the other disclaimers apply.
