Money is lost, yes, but if it’s not their money, why should they care? credit score hurts, unless they did a short sale, which would then not affect their credit score as much. Time, I guess that’s worth something. Taxes, what taxes? Upgrades, you’re assume they did upgrades. Like I said, if they didn’t have to pay closing cost w/ their own money, they wouldn’t lose anything. What if they stop paying for 6 months while living in it rent free? That’s worth something.
