How do I actually transfer the purchase money to Dubai?

Most buyers send funds by international SWIFT wire (2-5 business days) to the developer's escrow or their own UAE account. Your name must match across passport, bank account and title deed, and both banks will request source-of-funds evidence. Watch bank FX spreads of 1-3%, which on a $500,000 transfer can quietly cost $5,000-$15,000.
