ah, lack of planning by the previous owner.
The way to do it is to set up a trust, which owns the property. You make the intended relatives a partner in that trust. That way, when you pop yer clogs, they don't pay a single penny and inherit the property. Make sure a financial advisor is a silent partner, as they can settle any stalemate arguments that might arise later.
