So why would you be wanting him, what would his purpose on your property be?
I don't see why you would want to just keep him without a purpose. Animals are work even at the best times, and boars will grow tusks and can develop attitudes later on in life, even pet ones.
Our lap-dog of a boar, raised with every farm animal possible, is sweet as pie to us . . . . but we've had to finally eliminate the other animals that shared a large area with him. We never saw anything, but I'm guessing the food dominance took on a new twist once his tusks got longer. Gash on the cows utter, on the calf's leg, sheep's leg and now he's living alone. None of this happened until he reached 2.5 yrs. So plan on de-tusking along with the neuter.
I might keep a farm-pet for the fun of it, haven't yet but I might, but not a boar (or most any good size male) fixed or not.
Just my view on things
all the best.
