There seem to be a lot of people on here who haven't been able to sell their house in the UK and have rented it out, with a view to selling it when house prices pick up. I was in a similar situation myself when I moved to Adelaide in 1994.
May sound like a silly question but how are people planning to actually sell their homes when the time comes ? In the end I went back to England to sell my flat as I knew it would need a coat of paint and a bit of work done to make it look good for selling. Can agents in the UK do it all for you now without you even being here?? Obviously the internet and emails and electronic banking have made things so much easier than when I was facing this problem, and I would be interested to hear what ideas people have. May be of interest to people who haven't emigrated yet who are weighing up the options.
