We sold the house and moved to Australia with nowhere to live and no jobs to go to. It took us a long time to find work and in the meantime we had to live off the money from the sale of our house. We did eventually get sorted out but having to start all over again means we will probably still be paying off the mortgage after we retire.
Living somewhere else is not like going on holiday, you still have to work, pay the bills, deal with bureaucracy etc.
We have very little time or money for holidays and I now feel that if we had stayed in the UK, saved up and taken six months off work to visit Australia, we would have seen more of the country than we've in the seven years that we have lived here.
