The property is blooming very fast in Daubai, some of the apartment sold in hours, and it increasing to double just with in few months. Is it? What is the comments on it.

Hello all,
I am looking to buy some realty in Dubai and I wonder what are the best options…I mean where exactly to buy it – Jumeirah, Sports city…what is the best neibourhood?
As well, what type of visa do I need to buy property?
And at the end…could you please suggest some internet site with real pictures of properties…because all the sites I was looking were full of computer generated animations of villas…but not real pics

Thanks alot!
