The vast majority of people are on work visas and visas attached to properties are less secure. Indeed one of the major developers (not Damac) already has put all residency visas relating to property purchase on hold, pending the issue of a new set of rules. It could take anything from 2 days to 4 months to sort out visas, although possibly longer as it is doubtful that Damac would see this as any sort of priority.

As for what else you need to know - please read through the site, as these questions have been covered numerous times. And buy yourself a copy of Dubai Explorer.
