Where will the boat be kept? Living aboard in the northeast is something I wouldn't want to do.
The logistics of living on a mooring are not trivial. Having an inboard so you can charge the batteries in a reasonable time would be valuable. A watermaker will need far more power than the typical solar panel will provide. And how will you empty the holding tank? If you find a mooring with access to a public dock with water and pumpout facilities, that might work.
