BTW - if your plan is to buy a boat and take off immediately, well, that would be difficult. There is so much that has to be done just to get yourself and boat ready to be relatively self sufficient. Honestly, I would say it takes the better part of a year once you have a boat until you can comfortably leave. Just takes time to figure out what type of work is needed and get it done. It's not like house construction or flipping where you walk through with a clipboard and make a list, throw some time and labor at it, then put it on the market in 12 weeks.
I'll add some emphasis to this. We will have taken two years to get this current boat squared away... assuming I ever DO get the punch list down to manageable length.
This is starting with a 2006 boat, seemingly in decent shape... with lots (!!!) of little things the marine surveyor just might have missed along the way.
To be fair, some of that is also because this boat just began reaching time when many systems are reaching end of life... and the previous owner, at least (possibly previous ownerS), didn't do that whole maintenance things. Freshwater pump, microwave/convection, two ACs (three still to go), about half of the remaining original electronics, TVs, freshwater pressure regulator, cockpit shower, hydraulic lift platform controls, windlass, batteries, etc.
Plus some optional improvement. Add Inverter. Add some nav redundancy, etc.
Replacing stuff is actually sometimes the line of least resistance, but it's also often the case that it takes time to learn the system that needs attention, work out what the best fix might be, work out how to get access to the bits and pieces, work out what tools will be necessary, etc...
Buy the boat, spend a year (at least) learning it and getting it ready for the mission... or at least get it to the point where further repairs can be done on the move.
