Our EOI was selected in Feb, and we were hoping to leave for NZ end 2008, if all goes well with our application. We put our house on the market in May, thinking it would take at least six months to sell, and then, it sold after a month! The new owner wanted early occupation, so we are now renting. The funny thing is, we are a very cautious family, hate change, and were terrified of the moves involved, and yet, here we are in a rental, and it isn't the end of the world.
I'm starting to think the more you try and control this process and "do it right", the harder it will be for you when the timing goes haywire, as it is sure to do at some stage!
