He's paying a fraction of market rate rent and has saved a lot of money.

He's eating food out of the communal pool and it's a running gag at local restaurants that he eats two entrees. I think it's fair that he contributes something, like he is working, except for this summer when he said "take this job and shove it" because he was working for a crew where the foreman was twice his age but didn't have any sense for construction. Instead, he's doing a lot of work around the farm to fix things up, some of which is stuff we need and some of which is stuff he wants.

He expects to inherit the farm, will probably move to our other house if and when he is ready to co-habitate as opposed to getting on the housing ladder in the conventional way.

Thanks for the perspective. I have intuitively thought adults live at their parents' mostly out of need and much less often out of choice. The dynamics change in the latter case as two independent adults can make an agreement on how they see their relationship.
