This thread has been interesting, and definitely shows the wide variety of ideas of boating and living aboard.
Personally, I'm also of the vein of DIY. I've lived on the hook in an expensive part of the country, (Key West, FL), for about $1200 a month (including food,
dinghy dock, laundry and all) for a family of 4. We had the occasional more expensive repair, (like re-plumbing the head or re-plumbing the propane), we had to occasionally get a new dingy engine and once had a
dinghy and engine stolen... but these costs even including the "big ticket" items, were less expensive then it would have been to live ashore. It was a beautiful experience that I miss. I'm actually looking for another "fixer-upper" now... hoping my kids and I can move back onto a boat this year.
