Good luck if you follow the advice of the previous members - you might be able to decipher that they all work for DAMAC.
If you do decide to buy, the friendly helpful staff suddenly disappear, and you will most likely have a prolonged nightmare, with contractual errors (always to the advantage of DAMAC),project delays, sudden discounts off the property you just bought for everyone else, loads of 'extras' that you hadn't bargained for in your final bill.
DAMAC have been selling hard, building slow and having to sell even harder because they don't get much repeat business.
Since one of the nice people to respond earlier will no doubt come back and defend DAMAC, I suggest you hunt deeper for information. There are plenty of disgruntled investors out there and a lot recorded on the web. However DAMAC are also skillful at manipulating Google searches so you may have to go deeper than the first few pages.
