Hydra was an outright scam. I had a 2 bedroom villa for which I had paid a deposit of Dh110,000... however the continuous delays and then a change to the original house plans as well as an increase in the price forced me to rethink my position.
Then in early 2009 (I think), I was sent a threatening letter that stated if I didn't sign up to the increases stated above, I would lose my deposit... so I bit the bullet took the latter option, saying goodbye to my hard earned dirhams.
Although it was a lot of money gone, I certainly feel better about it, gaining experience can be an expensive commodity, lesson learned !!
The Real Estate market in the UAE was and still is a very big minefield... be careful where you step.
