If you own a one million dollar property that appreciates 10% unencumbered and loses 7% of value encumbered then you need to get a lot on your lease to make it make sense. What you gain from leaving the building empty is that you can sell to a big guy who wants the whole space. He won't do that if you give him six out of ten units and say "The other guys move out in five years" especially since the other guys will fleece you on buyout.
