Isn't that crazy? My lawyer said years ago you could file at 8am and be D by 5pm!! He said they had to change it to 30 days for a "cooling off" period because people were coming in from different states just to get D!
The 1 year requirement really buys you some time. A lot can happen in a year. I would say don't rush anything on the house unless you just get a really good deal.
Too bad about the trip, but maybe things will work out.
