You are letting your father suck you into a stupid head game. Just make up your mind to refuse to discuss what happens to property that you don't yet own. Who knows what your father will actually do between now and when he dies. (Is he actually terminally ill.) Even if he had a will made, wills can be changed. Do yourself a big favor and refuse to even discuss the matter. Someday, if you actually inherit something from your father, that will be the time to decide what you want to do with it. Don't count any chickens that haven't hatched yet.

Down the line, and not before, I would suggest that, if you actually inherit anything from your father that you don't really want, then sell it and keep the money. Don't even consider selling it to your brother. He would just end up saying that you sold it for more than it is worth and that you gyped him.

It is very uncool to talk about what is going to happen to someone's stuff when they die, especially when this is a person that you don't even talk to. You probably have real good reason not to talk to your father. So just leave it at that and be glad that you are the independent one.
