Hi Steve,
Have been following your posts with great interest – hope all is well after the flooding.  I've been looking closely at investing in the US at the moment, and am also inclined towards Miami at this point.  Your posts have been extremely useful in this regard – you are obviously well-researched and experienced, and I'm sure everyone following is most grateful for your willingness to share this hard-earned knowledge! 
My aim is to buy at least one property in the near future, but I'm also interested in your views for the next few years re: the Miami, possibly wider Florida, market.  Are you anticipating any form of 'double dip' in real estate prices there, but still consider going in now is worth it anyway?
I've been reading Harry S Dent Jnr's book 'The Great Depression Ahead – How to Prosper in the Debt Crisis of 2010-2012' , which is giving me a deeper understanding of the points you've been making above.  He and his team believe the US is in the 'eye of the storm' and will go through another dip within the next few years (although notes Florida is a great opportunity).
I'm interested to hear your views on this and how it may have factored into your decision to buy now.  I see from above that you're intending to buy at least one property shortly (which is also my intention), so will be interested to hear how you get on when you're over there, and how everything looks 'on the ground'. 
Regards and many thanks,
