Yes, the market is more difficult now, you have to be wise in your choices. Before anything you bought would double in value in 2 years. A few quick pointers for now:
1. Anything close to the monorail stations or tram service will do well over the next 2-3 years. Would be careful about Dubailand properties as it seems Dubailand attractions are delayed.
2. For off-plan buy something that will complete within 2-3 years max.
3. Stick to 1 or 2 bedrooms. 3 bedrooms are harder to resale.
4. In my opinion stay away from Damac.
5. Check availability or for a distressed resale in the Torch off-plan in Dubai Marina. I bought at AED 980 per sq ft in here. Typical good location, marina price is now around AED 1500 per sq ft Rumour is a Saudi investor has bought the land in front for a new shopping mall and luxury lifestyle arcade will be going infront and running back from the phase 1 of the marina. (aka tallest block on the planet).
6. You may find a few underpriced or launch price distressed resales in MAG 218 tower close to the Torch as develpment has slowed right down due to lack of workers. This has been resolved but means 1.5 year delay.
7. Check around Burj Dubai old town area - although may have missed the boat on that one as prices seems to have rocketed last year.
8. If buying to rent out on short term holiday lets, be careful about property from EMAAR, the lease for those units prohibits short term rentals.
9. JLT office space is a good option.
