I would trust your numbers and move on from this potential money drain. 

College campuses almost never drain.

He used actual fixer-uppers as comps and came in at 30-40K below value. 2K for those 3 appraisals down the drain. 

However, I made the argument to listing agent that they should want to spend the money at the very least to simply drain the basement water out since it's still an asset that is slowly deteriorating and losing value every day that the water sits there and investors/buyers will not want to take a risk on a property with a question mark like that.

Once your savings are drained and your credit card is maxed, they leave you cold.

Also make sure to do a drain inspection. ~$200 saved me $10k.. no brainer.

They are a major drain on time and resources. 

If the size if appropriate, then(2) Drain the unit completely. 

I feel like this is fair bc it is when their lease ends, and I'm not responsible for giving them any extra time while they were trying to sort things out with their roommates to sign a new lease with me.Honestly, at this point, I'd rather have them out of my property as they've been difficult to deal with during this process and other items have popped up in the past (e.g. they've clogged our kitchen sink by pouring excessive oil down the drain, broke the garage door within a year of their first lease, etc.)My questions are:-What happens if only 2 of the tenants vacate when the lease ends and stay for an extra week?
