What are the red flags when buying off-plan?

For off-plan, verify the project's RERA registration and permit on the Dubai REST app, and pay only into the project's DLD-approved escrow account - never a personal or general 'corporate' account. Warning signs: pressure to 'sign now, fix later', no developer NOC, prices well below market, and agents who can't show the escrow details. Verify everything in writing.
