Sometimes if someone has a good profession and gets hired long distance the new company will move you in order to get you there. I moved to DC and the newspaper I went to work for paid for my move and put me up in a furnished apartment till I found my own place a couple months later.
Personally I have found that there is no perfect time and I have moved across country with 2 children 4 times alone without a job to go to and somehow it always works out....
