It appears that many people are turning to boats after financial ruin.
I don't know about "many", but there are certainly some. All they did was exchange one set of problems for another, and they are still broke, just in a different location, with a problem they didn't have before- their home might sink.
If you want to live-aboard to expand your life and enjoy living, great! But if you think it is a great way to escape the burden of home ownership, you're wrong.
Living aboard is something you run TO, not a solution to whatever you are running away FROM.
