Oh wow, that is awesome that you have that much time to move out of the house. I don't think you would get that lucky here in the states. If the housing market is that crazy, I am surprised they didn't want immediate occupancy! Good luck with your continued hunt!
At this time it isn't common either. A lot of people have to leave in two or max three months, so we are quiet lukcy indeed :).... Next challenge : A new home sweet home for us ;) Thanks !!
