Since my mother is in intl. real estate, I am somewhat well-informed about the markets. Dubai real estate fell by 40%, the prices of the villas on the artificial "palm tree" fell from 3 million to about 1 million!



Also the Trup Tower was cancelled:

Although I have to admit that this is really impressive, if you do not look behind the scene (more than 70% of capacities in Dubai are EMPTY space):
1991:

2005:


But 1,140m Nakheel Tower is already planned to kick Burj Dubai from it's position:

While Kuwait will rise up it's Silk City Mubarak Tower:

But this was overdue to happen. It was an enormous speculation bubble, that bursted. You cannot build megacity capacities in a 1.3-million-city!
Anyway, the most stable real estate prices in the whole Middle East can be found in Tel Aviv the the Israeli seashore cities as a whole. Actually this is better than having the WTB, which is only a temporary title!
