Get your taxes done using TurboTax

Report it as a sale of home even if there was no profit ... especially if you got a 1099-S at closing.  Failure to report the sale will guarantee you an IRS audit in a couple of years ... make sure to check the 1099-S box.  Don't get hung up on the address entry ... enter whatever address the boat was registered to at the time even if it is the marina ... the address is not important.
