Thanks so much! I actually talked to my realtor today, who was very unfazed by the possibility that things might be pushed back a day or two, and really -- the sellers have moved out, they already had a previous buyer flake out on them, they really NEED this closing to happen, even if slightly delayed. So I'm thinking everything will work out OK.

(And I got into the house for a half-hour to measure and plan, and I'm so so so happy with it!)
