Last minute house fixing items

Everything seems to be falling apart at the last minute. The insurance agent I lined up suddenly came back with a price that’s twice what she originally quoted to me, so I have to scramble to get another insurance agent before next week. Also, the appraiser is asking for the owner to fix part of the floor in the dining room, and the contractor who’s supposed to be fixing the sewer line is suddenly MIA with the job half done (he was supposed to finish yesterday at the latest).
The owner’s willing to do the floor, but thinks he can’t get it done by Wednesday of next week, which means we might have to slide the closing date, which I really can’t do, because then I won’t have time to move before I have to be out of the house I’m renting.
