Do commercial properties in Dubai yield more than residential?

Usually yes on gross yield. Residential averages roughly 6-8% gross, while commercial ranges 6-12% by type - offices 6-10%, retail 7-12%, warehouses 8-12%. But commercial carries narrower buyer pools, slower resale (3-9 months on market), higher service charges and 5% VAT, so net returns land below the headline gross figures.
