What are the main off-plan payment plans in Dubai and which is best?

Common structures are 50/50, 60/40 and 80/20 (the share paid during construction versus at handover), plus post-handover plans that let you pay for years after completion, and 1% monthly plans from developers like Danube and Samana. The 60/40 is currently most common. The 'best' depends on your capital, timeline and cash flow; longer plans may carry a price premium.
