Is rental arbitrage (subletting for short stays) legal in Dubai?

Rental arbitrage - leasing a unit long-term then re-letting it as short-stay - is only legal with the landlord's written consent and a DET holiday-home permit held by you or a licensed operator. Subletting without permission breaches most tenancy contracts and DET rules, and enforcement is active. Confirm the current framework with DET before attempting it. Not financial advice.
