What this means is at the end of the day they can always bulldoze the Facility, sell the scrap metal, and sell off the land so in theory your offer shouldn't necessarily be below the "worth" of the real estate.I type that because at 30% occupancy you're flirting with the value being between Income Valuation vs.
