I discourage clients from planning their estates around specific assets. There may be a compelling reason to do it in rare instances, but in most cases, it can result in unintended consequences.
A Will is supposed to allow you to leave your property efficiently to your loved ones, but it rarely does that. Leaving property through a Will is like pouring a pitcher of water into cupped hands to take a drink. Most of the water spills onto the floor and disappears before you can use it properly.
