But remember that the WTS does not "own" the KHs. Each KH is held as a non-profit corporation with 3 elders from the congregation in whose territory the building sits acting as trustees (who do not own the building or land either). The WTS would have to dissolve a congregation to take over as the non-profit corporation.
Like that really means anything. They will dissolve whatever congs. they need or want to. Or they will simply tell the locals that they need to sell and give the money to WTS for the worldwide work. There are tighter controls since that one got away in Texas.
