I think JVS is a great investment and La Castas pro's for JVS are spot on "Very close to Emirates Hills and very expensive areas. From my experience in real estate, this tends to make prices go up. The prices there are very reasonable as well." JVS prices will shoot up nearer to the levels of the expensive areas in the next year.
I also think Sports City will be superb but you have to buy in the main canal area. I don't think you can go wrong if you buy near the top of the Canal next to the stadiums. Sports City, as a project, will be the next Marina. Sports always brings in visitors - it will probably be the main tourist attraction in Dubai. Also, Sports city is right next to JVS, so we expect a lot of people to live there long term as well because of the location. It will also be used by athletes for months at a time who will use the world class facilities and weather to train in. In terms of events, Dubai has already signed on several events - and we will see the creation of new tournaments to be played annually in Dubai (cricket, football and rugby being the main ones).
I also like City of Arabia but would hold off from investing because of the delays and the price rises. They are still doing the main infrastructure and are well behind on this. I have spoken to some developers and they say they are ready to build but can't as the ground work and infrastructure has not been finished by the master developer.
I can provide further information and and sales options if anyone is interested.
