Run Forrest, run!
Your less than 100% or more than 0% financial/ownership in this cabin is a surefire recipe for a lot of intractable unhappiness in the future. Sometimes you just have to suck it up and do the unpopular thing because it's the right thing. You seem to be working your way into rationalizing this by distracting yourself with details as opposed to focusing on "the big picture" wherein lies the simple answer to the question you posed
. Are you inclined to be a human doormat?
Apologize for the frankness, but this is really a "no-brainer", as you are hearing repeatedly in the responses to your thread.
appreciate the frankness. It’s,too,bad. This cabin is a really nice place. Lots of history. Sad to see it go. Also trying to manage family dynamics. It’s a very dysfunctional family.
and cabin aside even though Bil is a ******* I want to see him clean up/manup and succeed. I’m human.
just trying to put on a liberal ‘ kuum- by- ya hat here.
also in the back of my mind is I can rent a cabin for 1200 a week, power,ac, drive up, no work, nothing. Just enjoy.
cost of buying 50% of cabin,plus cabin costs = 3-4 weeks of rental for the rest of my life.
wish wife would just let the place go. It’s a building on the water. Who cares? Buy another place.
