A new rental index for Dubai to be published next week will show a 30% fall in rents since March for Palm Jumeirah villas.

Arabian Business has obtained details of the Landmark Advisory index, a rival to the official rental guide of the emirate's property watchdog, before its release early next week.

Other residential hotspots in Dubai such as apartments in Jumeirah Beach Residence (JBR) and townhouses in the Springs will show rental falls of eight percent compared to Landmark’s last index.
