My two cents:
I knew a guy who was semi-retired and kept his 30 footer on Lake Erie. He worked (if at all) between Thanksgiving and Memorial Day. He lived aboard all summer. His wife stayed at their condo in PA, she no interest in sailing. Winters he moved back with his wife.
Another couple I know plan to live aboard in the summer on the Chesapeake on their 30+ foot pilothouse. In the winter they store it and head to their condo in FLA and sail an 18 foot weekender. Works for them, too expensive I think for my budget.
This guy's life is my goal for retiring...if I ever get the chance.
The point is: Maybe try living next summer on board. This will at least give you a feel for it. You won't HAVE TO sell, rent, etc the house because it's only two months.
Hell 3-4 months? How bad could it hurt? Nothing ventured, nothing gained. He who hesitates is lost. Whether you think you can or you think you can't...either way you're right. And all those other appropriate saying...LOL
