Like most places in FL, Miami weather is horrible. I would move to LA just for the weather alone. Mind you, I wouldn't go anywhere near downtown LA but look at places like Thousand Oaks, Simi Valley, or Oxnard (you know this area much better than me).
That being said, the rental and housing markets have really become insane over the past 2 years or so, both in the US and Europe. I read somewhere that over 50% of Americans below 30 now live with their parents and have zero hopes of ever affording to buy a home. I also watched a recent documentary about the increasing number of people leaving the US to chase their American Dream abroad.
