Oh, I really feel for you - we had sold our house in the UK and booked flights etc. 10 days before we are due to fly, our buyers buyer pulled out of the chain. OMG what do we do i thought. We thought sod it and came anyway, rented a house here and both got jobs straightaway. Fortunately the house sale finally exchanged in December last year but lots of sleepless nights were involved.
We have now bought our own house and move in 2 weeks today, one thing I will say 'it's a whole lot easier buying and selling houses here'
Good luck with your house selling!
