The joys of remodeling, part umpty-dozenth: Got a surprise bill in the mail today for $12K we hadn't counted on. That's more than the last payment due on the whole job, which will still be owing when this is paid. The worst part is that $7K of it is for replacing the swamp cooler; we had understood that climate control was part of what we were paying for in our rent. As far as I'm concerned, the landlord should be paying for that, not us.
